Device for precise drilling of holes in wood. Overview of drill bits: for cutting, grinding, polishing, precision drilling. Drum or cylindrical

One of the most popular power tools, which is used with equal success in production and at home, is an electric drill.

Among other things:

• removal of traces of corrosion from the metal surface;
• removal of old paintwork;
• cleaning of welded seams, deburring;
• milling soft material;
• polishing of metal products, including those with complex geometry;
• grinding the inner surface of the holes;
• grinding the surface of wood;
• polishing products coated with varnish;
• glass polishing and polishing of their edges;
• grinding and polishing various small parts.

The industry offers a wide range of ready-made accessories, so for any type of work you can find the right tool. Some types of attachments can be used together, which allows you to turn the drill into a small portable machine.

When choosing a nozzle, in addition to its purpose, you should pay attention to the manufacturer and country of production. Too often you will find a cheap low-quality tool, the use of which will not give the desired effect, and in some cases can cause serious injury.

Drill bits, is it worth buying?

Most often, an electric drill with nozzles is used in the absence of a special tool, and its purchase is unjustified. For example, you should not buy a grinder if you need to clean one single workpiece. It is much more practical to buy a drill with a set of nozzles and use it as a universal tool.

It should be noted that the choice of devices for a drill is very wide. They are not limited to simple grinding and polishing tools. If necessary, a drill can take on the role of a milling cutter, screwdriver, electric jigsaw, construction mixer and even metal shears.

Note! Plus, a drill with a nozzle is a great option for processing workpieces in hard-to-reach places.

Among the shortcomings of this tool, one can only mention the low efficiency of an electric drill when working with some types of nozzles, for example, it is much easier to grind a large area with a full-fledged grinder. Nevertheless, given the affordable price of even the highest quality nozzles, a set of basic ones should be in every home workshop.

Nozzle types

There are a huge number of devices for a drill. Some of them are designed for easy drilling, others allow you to create large diameter holes, and others help in grinding and polishing. There are also highly specialized devices, for example, a cutter for a mini wood drill, which turns a hand tool into a mini milling machine.

A strictly vertical hole passing through the entire workpiece is not always required. There are times when it is necessary to drill at exactly the right angle, moreover, several parallel holes. Here the drilling angle limiter will come to the aid of the master. Basically, these are lightweight structures that are put on the drill and ensure its precise positioning.

Another useful accessory for an electric drill is a depth gauge. The limiter is included in the basic delivery of almost any drill. The device is extremely simple - it is a metal rod that does not allow drilling deeper than the specified value.

For grinding and polishing

One of the most popular nozzles are devices for grinding and polishing the surfaces of metal and wood products. They differ markedly from each other in execution and purpose.

Cymbal

They are almost a complete analogue of the grinding plates that are used in electric grinders. The only difference is that instead of a connecting thread, they have a pin that is clamped into the cartridge. Actually, if necessary, you can use the working part of the grinder for a drill, after screwing a regular bolt into it.

The material from which this nozzle is made can be any. There are metal models, plastic, often rubber. The latter accurately follow the contours of the workpiece, creating a perfectly flat surface. The cutting part of this nozzle is sandpaper. It is sold in the form of finished discs with a special coating that prevents slippage.

Cup

Cup-type nozzles are used for roughing the workpiece. With their help, remove the old paintwork from wood, remove scale from metal, and remove rust. Structurally, this is a bowl-shaped body, inside of which a stiff bristle of springy wire is laid. At the bottom of the cup there is a pin for fixing in the drill chuck.

Disc and fan

Disc nozzles have a device similar to cup nozzles. The only difference is that the brush is not limited by the size of the body, but, on the contrary, comes out of it, forming a kind of prickly "sun". The nozzle is convenient for processing large surfaces, but requires caution during operation - one ill-conceived movement is enough to ruin the product, and possibly get injured.

Fan nozzles have a similar design. Their working part is petals made of emery material on a cloth basis. This nozzle is convenient to work with aluminum parts, clean cast billets from slag.

Drum or cylindrical

Nozzles having the shape of a cylinder, outside of which an abrasive material (sandpaper) is fixed, are designed for processing the inner surfaces of cylindrical holes. Most often they are made of metal or rubber. By selecting the grit of the skin with this device, you can process a wide variety of materials, from wood to metal and glass.

Polishing tips

The final phase of product processing is its polishing. Polished parts that have been milled and varnished. This procedure is performed using special pastes that are applied to a soft moving surface. As such, felt, leather, foam rubber or fabric can be used. Structurally, this nozzle is a disk made of soft material, in the center of which there is a pin for fastening in the cartridge.

For curved cutting

There is an interesting device that allows you to turn a drill into a jigsaw. The device is fixed in the chuck and makes it possible to cut wood-based sheet material, plastic and even thin sheet metal. The cutting tool is a movable nail file.

This device is a useful thing in the household, but the nozzle has a rather high price. If you often need to make curved cuts, you should consider buying an inexpensive electric jigsaw.

There are other similar devices. Drill bits for drilling round holes in wood are very popular. They help to overcome the limitation on the size of the drill, which is typical for most models and drill a hole of any diameter.

For driving screws

Perhaps this is the simplest and most popular nozzle of all that exists, in fact it is a hardened bit with a cross for different sizes of screws. It is enough to clamp it into the chuck, and the electric drill will easily replace the screwdriver. The only condition for using the nozzle is that the drill must have a speed controller.

More complex devices are also on sale that allow you to tighten screws at different angles. Separately, flexible devices with a sheathed cable can be noted. With their help, you can work in the most inaccessible places.

Homemade tools for a drill

Despite the fact that the industry offers a wide range of nozzles, both in sets and individually, home craftsmen often make various attachments for a drill with their own hands. Such a desire can be caused by a number of reasons. Someone does not have a suitable nozzle at the right time, someone is not satisfied with the quality of those that go on sale.

Drill angle limiter

A very useful and very simple device is the angle limiter. Separately, it is worth noting that this nozzle performs two functions at once. It provides an accurate angle of travel of the drill and limits the depth of the hole.

The main part of the nozzle is a clamp with a thickening in the upper part. The clamp is attached to the body of the drill. Two holes with a diameter of 6 mm are made in the thickening. From a wire of the same diameter, a thrust bracket is bent with the required angle. A stop is attached to the bracket, which allows you to adjust the depth of the hole. It would be useful to make several interchangeable staples with the most popular parameters.

For cutting round workpieces

The basis of many homemade products is a circle made of plywood or other sheet material. Most often it is cut with a jigsaw, but the same can be done with a drill. To do this, you just need to make a simple holder that works on the principle of a compass.

The device is a pin that is attached to the body of the drill on a clamp. A vertical stop moves along the pin, it is fixed in the required position. The stop with a pointed end is held on the workpiece, a rotating drill cuts out a circle. Instead of a drill, it is better to use a cylindrical cutter, with its help it is easy to make a high-quality cut without much effort.

Adapter for miniature drills

The chuck of a conventional drill has a limit on the maximum and minimum diameter of the drill, and it is often necessary to make a hole with a mini-drill with a diameter of up to 0.1 mm. A standard chuck cannot crimp a small shank, but if you first clamp the drill into a collet chuck for an electric motor, and then fix it in a drill chuck, the problem will disappear.

Milling attachment

Not everyone has a milling machine; a milling nozzle for a wood drill can partially replace it. By supplementing the electric drill with a simple latch, you can make grooves of the required configuration. If necessary, such a device will help to make a groove and a tenon for connecting parts or a shaped rail of a small section.

An electric drill is the best assistant for a home master. Anyone who has this versatile tool in the workshop should purchase a set of attachments. This will make it possible to significantly expand the capabilities of the workshop, and besides, it will save money, because a drill with nozzles is obviously cheaper than all the tools that it can replace.

The use of special devices clamped in the chuck of this power tool makes it truly multifunctional. For example, they can even cut sheet iron. Given the variety of nozzles for a woodworking drill, it is unrealistic to dwell on each of them in one article. We will deal only with nozzles that allow using a drill to quickly and efficiently perform surface machining of wood.

What is it? Preliminary cleaning of the surface (rough), deburring, grinding and bringing to a mirror finish (polishing). All other technological operations with wood - milling, drilling, screwing fasteners, cutting - do not belong to the concept of "processing". This is what the author comes from. The difference in the listed types of work in relation to nozzles is in the speed of rotation of the drill chuck and the type of fixture. And which one to choose is decided mainly based on the required degree of processing of the tree and its species (that is, the density of the structure).

Indicative prices, in relation to the Moscow region, in Russian rubles

By type of abrasive

• Rigid fabric.
• Foam rubber.
• Plastic.
• Sandpaper of different grain sizes.
• Rubber.
• Cord brush.

According to the degree of wood processing

• Abrasive (rough).
• Grinding.
• Polishing (soft and super soft nozzles).

By execution

Depending on the configuration, the attachments are used for more than just surface treatment of wood. With their help, you can grind (polish) holes (as a replacement). This is easy to do with cylindrical (thin) or conical devices.

Poppet nozzles

Available in several modifications. The difference is in the form of abrasive material. If wood sanding is required, then it is rubber (the preferred option) or plastic. For polishing, it is advisable to purchase nozzles, on the working part of which fine-grained sandpaper is fixed. They can achieve better (fine) processing of wood.

Recommendation - effective processing of wood with a nozzle on a plate-type drill is difficult because it is difficult to keep the drill in a strictly vertical position. To achieve a good result, it is desirable to fix the tool, and move the workpiece relative to the working part. The machine for fastening the drill is easy to assemble yourself.

Price - from 162

There are nozzles on sale that provide for adjusting the angle of the abrasive attachment pin. But they are quite expensive, and not every store can buy them. Therefore, a machine with the ability to change the position of the drill is a more acceptable solution.

Drum nozzles

Mainly used for processing the end parts of wooden blanks and holes. They have a cylindrical shape and differ in the way the emery tape is attached - using a bolt or special inflatable blocks. Some types of nozzles of this type are also used in everyday life for plucking (at low speed) birds when it comes to a large amount of work.

Price - from 178

cup nozzles

The range is significant. Differences and in the sizes, and in an abrasive material. It can be either metal "villi" (hard wire), or dense fabric, leather, felt, and even foam rubber. The choice of fixture is determined by the desired degree of wood processing. If you want to achieve a sharper selection of the texture of the material, then the wood pulp is sampled with just such nozzles.

Price – from 189

A variety of devices in this group are disc nozzles. What is the difference, it is clear from the figure (the villi are located diametrically).

Price – from 398

Fan devices can also be attributed to this type of nozzles. They are also called petal.

The main purpose is to polish the wood at the final stage of processing.

What to consider when choosing nozzles for a drill

• With the help of nozzles, for example, the same grinding ones, it is possible to process not only wood, but also other materials - metal, glass, ceramics, and so on. You just need to select the appropriate modification of the device.
• According to the reviews of master practitioners, identical nozzles from different manufacturers can differ greatly in efficiency and duration of use. Therefore, you should not save on the purchase of products of a little-known brand. It is not a fact that such a device after a short-term use will not become unusable.
• Even an expensive nozzle will cost much less than a special power tool. For example, a grinding machine, for which you still have to additionally purchase the appropriate accessories (cloth, wheel, etc.), depending on the type of product.
• When choosing any nozzle, you should focus on such features of your electric drill: power, cartridge size, the ability to control speed. Otherwise, the convenience of using the device and the high quality of wood processing are not guaranteed.

The article discusses the main types of nozzles for a drill. Each group is available in several modifications; in addition, manufacturers regularly supply some new products to the market. Therefore, the choice in terms of size, configuration, abrasive must be made for a specific technological operation, especially since it is, and quite large. This allows you to achieve the highest quality result in wood processing. Considering that it is impossible to foresee everything, especially without having a lot of practical experience with nozzles, it is better to purchase them in specialized stores. Focusing on the characteristics of the buyer's drill, the seller will help you make the best choice.

It turns out that the drill is allowed not only to create holes, but also to perform many other operations. Let us consider in more detail what are the devices for a drill and what they are intended for.

All nozzles operated together with a drill are conditionally divided according to the type of shank:

1. Cylindrical - fits a standard three-jaw chuck;
2. Threaded - fixed to the spindles with a thread;
3. Adapters - allow you to use nozzles from a grinder (angle grinder) with a drill.

The next classification feature is the actions for which the devices are intended:

• Surface cleaning;
• Grinding details;
• Polishing products;
• Cutting materials;
• Mixing solutions;
• Twisting and twisting.

Racks, parallel stops and guides stand out as a separate group, allowing precise drilling of parts of various configurations at any angle.

Flexible Shaft - Expanding the Functionality of the Drill

Video about the functions of the flexible shaft in a mini drill

A good addition to the drill is a flexible shaft, which simplifies the performance of such work as drilling, grinding, engraving and others. The device is easily fixed in the cartridge at one end, and on the other side there is a handle with a clutch designed to fix various nozzles. The use of a shaft allows you to process products where it is impossible to get close due to the large body of the electric drill. When using the nozzle, the hand does not get tired, which means that you can work longer and more accurately.

Popular models of flexible shafts:

A flexible shaft is purchased separately or several nozzles are included with it - by purchasing such a set, you can save money, try different nozzles in operation, and then buy only the necessary consumables.

Grinding and polishing surfaces with a drill

Video instruction on how to make a roller on a drill with your own hands

For a drill, there are special nozzles for grinding - support plates with a pin in the center. Available in diameters up to 125 mm and come in various designs:

• Rigid with Velcro, on which sandpaper is attached;
• Soft rubber with a clamping screw, using a simple abrasive paper and capable of processing wavy surfaces;
• Combined with a shank that has two positions: a rigid lock and the ability to change the inclination depending on the position of the tool.

Paired with a drill for grinding plastic, wood or metal, nozzles in the form of a petal disk can be used. Toolings are radially placed abrasive sheets with different grit sizes – for final or roughing passes.

The nozzle on the drill for removing plaque, rust or polishing is made of a similar design. The difference lies in the working surfaces - it can be felt or a steel brush.

The drill can be called a universal tool, although initially it was intended only for drilling. Various accessories for the drill significantly expand the scope of its application.

Milling cutter for drill - for wood, metal, plastic, concrete, video

The main functional part of the drill is the motor, which drives the electric shaft. In the future, the load is transferred to the actuators, one of them may be a cutter for a drill. The cutter represents a tool like a screwdriver or a drill. Depending on the configuration and width of the cutting part, recesses of various profiles, selections and grooves can be created in the body of the material being processed.

Features of working with a drill with a cutter

Milling involves the processing of material with a cutter installed in a fixed body of a power device. In this case, it is assumed that the speed is regulated on the tool, the depth of entry into the material being processed. But the array on which the action is performed must move. Such machines are called milling machines.

It is possible to use a drill as a milling cutter only in some cases. The reason is the special accuracy of work, a large effort on the drive. The cutters for the drill are specially designed, taking into account the power and methods of regulating the device. Of great importance for work is the shape of the drill and its center of gravity.

Features of using a cutter for a drill:

• a change in the load vector can damage the gearbox if additional pressure is applied to the workpiece;
• the motor overheats, frequent rest is required;
• load on the plastic case can lead to armature skew and deformation;
• fastening in a cartridge with a horizontal axis of work is unreliable.

All this suggests that the drill as a milling cutter works in an unusual position for it and with uncharacteristic directions of resistance forces. Work with a milling nozzle for a drill, you need to slowly, with caution.

Woodwork

The tool is a shank for fixing in a chuck and a cutter, which is made of special steel. Initially, the cutter is sharpened for a specific operation. The tooling is made with strict precision to eliminate backlash. Sharpening and steel in hardness are selected according to the characteristics of the material being processed.

It is better to select the profile and depth of cut on a sample of material of similar hardness. In this case, the drill is installed in the clamps at the desired distance and the speed is selected corresponding to the work performed.

For attachment to a drill, only end mills with a shank are used. For long work without sharpening, it is better to choose cutters for plywood. They cannot be sharpened on their own.

A wood cutter for a drill differs in the type of processing:

• mugs - round the corners;
• V-shaped - make a sample in the body of the workpiece;
• disk and fold - create grooves;
• fillet - an internal groove on the edge;
• dovetail - connecting nodes for spike-groove;
• edging - process the edges of the planes.

Cutters for wood are distinguished by their soft effect on the material in order to prevent chipping and hardening of the edge to brittleness.

Features of milling cutters with shanks for metal processing

Metal is a solid material with a uniform crystal lattice. It is processed rigidly, the main indicator is the speed of work.

Depending on the desired result, cutters for metal of various configurations are used for drilling:

• end;
• corner;
• cylindrical;
• disk;
• terminal.

End cutters are used for vertical processing of metal. More often they process a plane.

If the teeth are located on the end and side edge of the flat disk, it is possible to drill a recessed profile on the plane. This is how grooves and grooves are made. If you use not a disk, a cylinder with smoothly curved grooves, you can process a horizontal surface, remove a layer, smooth out irregularities. For each operation, a special cutter for metal for a drill is selected. In this case, you should be aware of the load on the motor and bearings, avoiding overheating of the tool.

The requirement for the manufacture of the cutter is stringent. The tool must work efficiently, keeping the sharpness of the cutting surface for a long time. Often, in order to save expensive carbide steel, the cutters are made prefabricated, the body is made of ordinary steel, and the teeth are made of alloys.

Cutters should be purchased only from reputable manufacturers. At the same time, check the quality of sharpening, the uniformity of the structure, pay attention to the material of the cutting edge. Particularly check the tightness of the prefabricated milling cutters.

The cutter, like any cutting tool, requires careful handling. The cutting edge does not tolerate heat, vibration, or misuse.

We process plastic with a drill with a cutter

A feature of plastic processing is its viscosity. When exposed to a cutter at high speed, the plastic first begins to wrap around the cutter, and then liquefies. Therefore, the selection of drills and the processing speed of each polymer causes certain difficulties. A plastic cutter for a drill is selected depending on the type of material:

• thermoplastics;
• thermoplastics.

From the name it is clear that thermoplastics become fluid under the influence of temperature, the chips of such materials are drained, with melted edges. Thermoplastics are not subject to softening when heated. Often this material is produced with reinforcement. Based on the properties of the polymer, cutters and processing mode are selected.

Thermosetting plastics are machined with multiple cutters while maintaining smooth processing. The depth of one cut should not exceed 2.5 mm. Otherwise, you can get the destruction of the treated surface. Taking into account the artificiality of the material, it is necessary to organize the suction of microparticles so that dust does not enter the respiratory organs of the worker.

Soft material should be cut with double-thread cutters at low speed so that the material does not “flow”. For sheet plastic, it is better to use compression cutters for edge processing.

Drilling concrete

If there is a need to process the structure with a concrete cutter for a drill, diamond crowns with external cutters are used. The cutter is unscrewed from the base, shank. The victorious layer cleans the hole well, provided that a powerful drill works in shockless mode. Such crowns are used to remove ceramic tiles from the wall, for fine cleaning.

The use of pobedite crowns for drilling is fraught with danger. The drill must be held strongly, expecting a jerk, as the density of the material in the wall can change, and the force of impact will create a blow.

Why do you need a drill on a magnetic bed

When developing a drill on a magnetic bed, they were guided by the problem of creating holes in multi-ton metal structures that cannot be moved. Such farms, like a large magnet, attract a pair with an opposite charge. The creation of a charged bed for a drill solved the problem of fixing a tool for drilling holes with high accuracy.

Drilling large holes in metal is performed with different nozzles, including the use of a drill bit for a drill on a magnetic bed. Typically, such a nozzle is used in the form of a hollow crown. Drilling with a drill on a magnet according to the marking is guaranteed to be accurate. As long as voltage is applied to the frame, the drill is held on the plane with a force of several tons per square centimeter. After turning off the current, the installation is moved to a new place easily, its weight does not exceed 25 kg.

A hole cutter can drill a hole in a structure up to 130 mm in diameter.

Cutter for metal for a drill - the ability to expand the scope of the tool

The same tool can do different jobs. Using different attachments, the drill can become a mixer or grinder. The choice of various nozzles for power tools allows in some cases to get by with one basic module. In fact, the main component of any power tool is an electric motor in a housing. The rest is a matter of technique, more precisely, the question of choosing the right nozzle.

By installing the cutter in a home drill, you get a manual router. Although it is not as convenient as the original, it is possible to perform elementary work. In this case, you do not spend money on another power tool.

A good example of how you can attach a tool to a wooden block

Metal processing with a drill

The use of a drill as a primitive router has long been practiced by amateur locksmiths. Ever since Soviet times, cones and countersinks have been sold in hardware stores for boring holes and primary processing of metals.

Cone mounted on the tool, you can bore holes

A cone cutter is actually a peeling cutter, in essence a mechanized file. But the countersink has all the signs of a real cutter.

Valve seats are restored with a special countersink

Countersinks (or countersinks) allow you to perform not only rough processing of holes, but also form a recess of a given shape. You can use drills and standard cutters, but consider some features:

1. The drill has a lower speed compared to the router, so the quality of the cut is much worse.
2. Shaft bearings are designed for a different load vector - longitudinal.

Transverse forces during metal milling can quickly damage the gearbox. Therefore, the pressure on the workpiece must be moderate, and this increases the processing time.

3. The electric motor of the drill is not designed for continuous operation, after several passes of the cutter, it is necessary to rest the power tool.
4. Most modern power tools have a plastic gearbox housing.

With increased lateral loads, it deforms. In addition to the fact that the housing can simply break, the skew of the armature in the stator leads to increased mechanical wear of the engine.

5. The collet chuck of an electric drill, with lateral loads on the cutter, can give up the mount, and then you can either spoil the workpiece, or the falling milling nozzle will cause injury.
6. And most importantly, safety.

The absence of the so-called “shoe”, or thrust plate, as on a regular router, makes the job dangerous. When working with end or face mills, it is still possible to control the tool with the force of the hands. But disc cutters will simply pull the drill out of your hands.

Hence the conclusion: It is possible to work with a drill as a metal router, but subject to a number of rules and precautions.

The best solution is to make a router from a drill with your own hands

In fact, it will be necessary to make a fixing bracket and a primitive milling plate.

If the tool is fixed on the base, then you can make some kind of milling cutter out of it.

Aesthetics in such a homemade product is in last place, the main thing is to ensure the reliable fastening of the tool and the rigidity of the structure. For convenience, you can equip the device with comfortable handles for moving around the workpiece. And also take out the switch, since the trigger trigger of the drill is not the most convenient solution for the router.

You can adjust the immersion depth by simply moving the drill body along the fixing clamps. With due diligence, a more advanced design is made. With a microlift, like on a real manual router. With such a device, it is already possible to take on serious work, not forgetting about the features of a power tool.

Homemade design of a milling cutter from a drill with a microlift

IMPORTANT! The body of the electric drill is elongated along the axis of the shaft, which increases the center of gravity and makes the structure unstable.

This danger should not be forgotten during intensive work. If you have made an unequivocal decision to make a milling cutter from a hand drill, pay attention to the stationary solution to the issue. You can build a drill into a homemade milling machine.

Milling machine from plywood and an electric drill

This option is relatively safe and allows you to perform more accurate work. If the drill mount is easily removable, you can quickly change the purpose of the tool. That is, both the drill itself and the stationary milling cutter remain in the arsenal. At the same time, typical shortcomings will not go anywhere - as before, you work at low speeds, and the drill wears out with side loads.

Homemade cutters

As soon as you can make a homemade router - why not start creating cutters. It is quite possible to make cutters and nozzles from improvised materials, the quality of which is superior to Chinese counterparts J. At the same time, the cost of these devices tends to zero.

From a plywood cylinder and glued sandpaper petals, a convenient grinding drum is obtained.

By combining a suitable axle and a wheel from a flint lighter, we get an excellent micro-cutter. The quality of the material is at the highest level, such a nozzle works for a long time. When critical wear is reached, simply change the working ring.

The original decision to make a micro-mill for small parts

Having properly turned the dowel, you can make an end or cut-off cutter. Such a nozzle will work not only on plastic and wood, but also on non-ferrous metals.

Homemade dowel cutter

There are no limits to initiative. Each DIY homemade tool makes a tool that allows you to perform personal tasks, as opposed to standard factory fixtures.

Working with wood and plastic blanks using a homemade router

If working on metal with a milling cutter and a hand drill is quite difficult, processing wood with such a kit is a real pleasure. Using the developments described in the previous paragraphs, it is possible to perform milling of any complexity on wooden blanks. Wood cutters for drills are available in a sufficient range.

We put a wood cutter on a power tool

In addition, with a certain skill, any cutter for a manual router can be securely fixed in the collet chuck of an electric drill. The main thing is that the shank is cylindrical, not tapered. And if you fundamentally do not want to buy a separate manual router, you can use a ready-made industrial solution.

Drill mount imitating the work of a manual milling cutter

Such a device is safe, functional, but at the same time quite expensive financially. Although compared to the new milling cutter, it looks attractive.

Drill accessories: for milling, sharpening drills, perpendicular drilling, metal cutting and others

Few of the users know that an ordinary drill can perform very unusual functions besides drilling. For these purposes, there are very original devices for a drill that can expand its scope. Consider the varieties of nozzles and attachments that turn the drill into a completely different unit, capable of performing functions unusual for it at the household level.

Stops

This type of device is the most widely represented and has many interpretations.

To help the carpenter

The milling attachment turns an ordinary drill into a small home machine, which is used in furniture repair. By turning on low speeds and holding the device in a special mount, you can make a selection in the right place or machine a side groove.

Great precision in surface treatment is not expected, but this is not necessary, for example, when installing piano hinges - nothing is visible under them anyway.

Original nozzles

Sometimes it is necessary to drill holes in a very hard-to-reach place where a standard product does not fit due to dimensions, then original nozzles are used for drilling at different angles. The angle drive is ideal for use with any electric or cordless tool because it has its own chuck where the drills are clamped and the torque is transmitted through a gearbox and shank that is fixed in the main drill.

Such a device can be used not only for drilling, but also for tightening fasteners (screws, self-tapping screws and screws), cleaning and polishing hard-to-reach places - we clamp the desired bit or nozzle and perform the intended amount of work.

There are very unusual applications for devices that are used for electric drills - pumps. They cannot work for a long time - they can be used to quickly pump out viscous paint residues from a barrel or groundwater that has leaked into the cellar. Their performance is not very large, but you have nowhere to rush. The body of the nozzles is made of durable plastic, the service life is short, but the price is low.

Racks

To accurately drill the necessary holes in various materials, special racks or guide attachments are used, which can be purchased in stores - they provide vertical movement of the drill clamped in a special basket. Their compactness, smooth running and accurate metric scale make them attractive for small workshop equipment, where the DIYer can accurately drill any holes, even in round objects.

A small vise with clamped workpiece can be placed anywhere on the bed and firmly fixed thanks to the grooves cut in the base.

Unique whetstone

Special attachments can be installed on the drill for sharpening various tools - it turns into a mini sharpener that can be used to sharpen drills, circular saw blades, chisels, knives and various types of planers. The value of these attachments is that they help to significantly save the family budget - the services of professional grinders of similar tools, especially drills, are at a rather high price level.

The device of such nozzles allows you to work at different angles, and a cylindrical nozzle is used to sharpen drills. To sharpen other tools, special devices are used.

The photo shows the original nozzle for sharpening drills of any diameter and the machine for straightening circular saws. Installing various nozzles on a drill is not particularly difficult.

Woodworking

A drill can be used not only for drilling and as a mixer, it is worth attaching a special device to it - it turns into an original machine tool or a wood jigsaw.

Lathe

What home master does not dream of his own mini woodworking machine, but such devices are very expensive. There is a way out - these are unique attachments to a hand drill, which have a different design and the appropriate tool for the job. These devices are not suitable for serial production of carved balusters and coffee table legs, but it would be advisable to use them in a country house or a country house.

The design of the turning attachment for a drill is very simple and compact, any user can work - all you need is the desire and slowness of action.

jigsaw

It is hard to believe that a jigsaw can be made from an electric drill, these are quite different tools in their design, but nothing is impossible in the world. There was a designer who invented a nozzle that converts the rotation of a drill into reciprocating movements of a saw on a tree. Now you can use a drill to cut boards of various thicknesses, and lovers of filigree woodwork can cut unique patterns from plywood with a jigsaw.

Sheet metal cutting

There are special attachments for cutting drills - they were developed by leading engineers of companies that produce various models of drills to make it easier to work with roofing material. Working on the roof does not allow you to take a lot of tools with you, and going down each time to trim the excess on stationary equipment is troublesome.

Using an ordinary cordless drill, you can cut off the desired strip from the steel sheet right on the spot or remove the excess. Using such a nozzle for cutting metal, you can cut a metal mesh, thick plastic, cut out a part of the required configuration and size from a whole sheet.

The unique device freely cuts metal, while you can change the angle of the tool and work not only at a right angle of 90 degrees, as ordinary metal scissors do.

On the basis of an electric or cordless drill in a small workshop, you can make many useful tools with your own hands, for example:

• a device for a drill in the form of a drilling machine;
• grinder;
• sharpener for knives and scissors.

Some craftsmen even make home-made drills of various capacities, which they use during the repair of household appliances, where it would be problematic to use a standard drill.

To drill a hole of the required diameter in a workpiece or part, there are special nozzle templates that facilitate the work of users who are a little unsure of their abilities - they call them a jig. There are already standard sizes for various operations, there are professional templates made of steel, and for domestic use - made of plastic or durable plastic.

Drill attachments, as well as attachments for this power tool, endow it with new functions and the ability to successfully solve various technological problems. Devices for equipping a drill allow it to be used not only for drilling, but also as a power saw, milling cutter, small lathe or even a pump for pumping liquids. Modern manufacturers offer a wide variety of nozzles and attachments that make the drill truly multifunctional.

Of course, nozzles and other devices will not make a drill device comparable in performance and processing accuracy with specialized equipment, but it can be used quite successfully to solve simple technological problems with their help. It is very convenient to use the elements of additional equipment of the drill to solve construction and repair tasks, as well as many other issues related to the maintenance of housing in proper condition.

Varieties of devices for additional equipment of the drill

The most common is a drill attachment such as a stop, which allows you to easily and quickly drill holes to the required depth. The design of the simplest thrust fixture includes an auxiliary handle and the thrust itself, on the surface of which a metric scale is applied.

A more complex design and, accordingly, greater functionality has a parallel stop, with which you can control not only the depth of the hole being made, but also the position of its axis relative to the surface of the workpiece or structure. Attachments of this type are also available for tools used in construction and repair, and for wood drills.

Parallel stops, designed for use with construction and repair tools, are installed on powerful drills, with which they drill holes in concrete and brick building structures. This type of attachment consists of a stop with a scale and an auxiliary handle for a drill. Some models of rip fences have a built-in suction for removing waste products, which is connected to a vacuum cleaner.

Popular among home craftsmen are drill attachments, with which it can be used to perform carpentry work. A drill equipped with such an attachment is, in fact, a small milling machine. In its design there is a vertical rack with guides along which a special basket with a power tool fixed in it moves. Of course, this one is not able to provide the same accuracy and productivity of the processing performed as specialized equipment, but it is suitable for simple work in the home workshop.

A fairly large category among the elements of additional equipment of a hand-held electric tool is nozzles and attachments for a drill, with which you can perform drilling at an angle. Such a device for drilling holes works where it is not possible to use a conventional drill. The working head, depending on the model of this equipment, can be located at different angles (up to 90 °) with respect to the axis of rotation of the main drill chuck. The most popular and in demand are devices for drilling at an angle of 90 degrees.

Devices for drilling holes are widely represented on the modern market, which allow not only to limit the depth of the holes created and control the verticality of their axis, but also to use the drill as a small milling cutter. Such devices are especially popular among home craftsmen who are independently engaged in the manufacture of furniture.

When using various working attachments on a drill for woodworking, it is possible to perform many technological operations (in particular, side drilling of holes in products of a round or more complex configuration, requiring the use of special liners). On some models of such devices, special suction devices are installed, connected to a vacuum cleaner, with the help of which dust and small chips are removed from the processing area. It should be borne in mind that even such functional devices do not allow you to make a full-fledged hand mill from a drill, which has the same operational capabilities, but provides higher accuracy and quality of the processing performed.

Dust extractor for drill

No one will dispute the fact that it is much more convenient to use not a drill, but a drilling machine to form holes (and the accuracy of processing using stationary equipment is higher). Meanwhile, it is also possible from a hand-held power tool, for which it is used. Most modern models of such a device are equipped with a vise for fixing the part during processing, as well as a bed along which such a vise can move freely. The power tool itself is placed in a special drill holder (basket), which is a universal clamping device and can be used for almost any model of drilling tool. Such a device, on the rack of which an accurate metric scale is applied, is a very useful acquisition for any home craftsman, as it allows you to make holes with less labor and higher accuracy.

Attachments to the drill are very popular, allowing it to be used as a wood lathe. Such equipment is fixed on the desktop, and the drill itself acts as its drive mechanism. To install the drill in the design of such a prefix, a special stand and a mounting mechanism are used.

Such consoles are available in various designs, with a different set of cutting tools and fixtures, make it easy to realize the dream of many home craftsmen to have their own lathe at their disposal. Of course, a lathe driven by a conventional electric drill cannot be compared with specialized equipment either in terms of service life or in terms of accuracy and productivity of the processing performed. If you use such an attachment in intensive mode, the electric drill will not withstand significant and prolonged loads and will eventually fail. That is why, in order not to be left without a drill, such an attachment should be used to perform simple and not too long turning woodwork.

The most popular drill attachments include attachments that allow you to turn such a tool into an electric sharpener or emery. With their installation, there are no difficulties even for inexperienced craftsmen. Such attachments can be used not only for sharpening knives and circular saw blades, but also for restoring the geometric parameters of drills, turning tools, chisels and planer knives. Thus, using such devices on a sharpening drill, you can not only solve many household issues with their help, but save on contacting qualified specialists. Even those who do not have experience in this field can successfully use such emery, including for sharpening cutting tools.

Additional equipment for a drill is necessary not only for home craftsmen, but also for professional furniture makers. Such equipment, in particular, includes a milling attachment, with which grooves are made in joinery and furniture elements to create corner joints. When using such an attachment, there is no need to fix the workpieces in the clamping device. It provides high processing accuracy, and special adjusting elements are provided in its equipment to create a groove of the required width and depth.

In order to effectively use the tools driven by the drill even in the most inaccessible places, you can purchase a flexible drive or an angle adapter.

The flexible drive and the angled nozzle on the drill are fixed at one end in the drill chuck. Their second end is equipped with a clamping device in which drilling, milling, abrasive and any other tool with a shank of a suitable diameter can be fixed. When choosing between two such devices, it should be borne in mind that the flexible drive has more possibilities in terms of processing hard-to-reach places than the angled nozzle for a drill. The bending angle of such a drive is not limited to 90°, it can be any.

Application examples for angled nozzles

The question of whether it is possible to use an electric drill as a pump drive for pumping liquids is not without meaning. In order to practically solve such a problem, you can not come up with various homemade products, do not rack your brains over making a reliable mount for a drill on a typical pump housing and over which adapter to use. All these issues have already been thought out by specialists and implemented in the design of the attachment-pump.

Such a pump for a drill, although not intended for long-term and intensive use, is able to effectively solve many problems. In particular, it can successfully pump small volumes of both viscous liquids (such as oil or paint) as well as ordinary water. To change the pumping speed of a liquid medium, it is enough to change the number of revolutions made by the drill chuck. Since drill pump housings are usually made of plastic, they do not have a long service life, but this disadvantage is compensated by the low cost of such devices.

Electric drills are often used in combination with special templates, which not only increase the accuracy of drilling and further assembly, but also significantly speed up the processing process. Templates for professionals are made of metal, retain their geometric parameters for a long time. For home use, you can purchase an inexpensive plastic template, which, although not as durable as their metal counterpart, provides high precision machining.

The meaning of drilling templates lies in the fact that their design includes the sizes and arrangement of holes most often performed in elements of furniture structures. So, there are templates designed for drilling holes for fixing furniture hinges, inserting locks and installing furniture ties. In such templates, not only the distance between the holes being made is precisely maintained, but also the distance at which such holes should be located from the edge of the workpiece.

Types of nozzles for drills

The nozzles used with drills are also used to expand the functionality of the latter. This includes, in particular, a range of drill bits for cutting sheet metal. Such nozzles for a metal cutting drill can work as punching or nibbling scissors. Even when used with a conventional drill or screwdriver, they show high efficiency. For example, such an attachment for a cutting drill is able to cope with a metal sheet up to 1.5 mm thick, a mesh made of metal, and thick plastic.

In most cases, it is better to use a drill attachment for cutting metal, rather than a manual or electric jigsaw. This is explained by the fact that the jigsaw, like many other devices with which you can cut sheet metal, contribute to intense heating of the processing zone. This may cause the protective coating applied to the surface of the sheet to burn off. Among the most popular drill bits used for cutting sheet metal are devices called "Cricket" and "Steel Beaver", as well as devices that look like metal shears, but are powered by a drill or screwdriver.

Among home craftsmen, as well as those who are professionally engaged in car body repair, grinding and polishing nozzles for drills are very popular. The working body that such grinding attachments are equipped with can be a drum with sandpaper glued to its surface, as well as a felt or felt disk.

The material through which the nozzle on the drill for grinding will be in contact with the surface to be treated is selected depending on the nature of the technological task. Thus, a grinding tool, with which coarser processing is performed, is often made of an abrasive material of the appropriate grain size, and felt or felt is glued onto the polishing material. As a polishing tool, a brush attachment is also used, which is installed in the drill chuck using its shank.

The drill attachment for polishing a car can be used not only after a body repair has been completed, but also in cases where the owner of the vehicle wants to give it a pristine shining look. If you want to save on the purchase of grinding nozzles for a drill, you can make such a device with your own hands. For this, a home-made wooden drum is suitable, in the central part of which it is necessary to securely fix the shank. With the help of this structural element, such a device will be fixed in the drill chuck. Grinding and polishing with a drill using such a drum can be carried out using materials such as sandpaper, felt and felt.

The nozzles for power tools used for cleaning products from various materials work on a similar principle. So, for cleaning metal products, metal and abrasive nozzles, as well as a brush nozzle, can be used. The brush is made of metal wire and allows you to effectively clean the surface of the product from dirt, rust and remnants of the old paintwork. The brush itself, which is equipped with such nozzles, can be located on the end or side of the device (it all depends on the tasks to be solved). Similar nozzles also differ in the material from which the brush is made. Such materials, in particular, can be polymer fibers or metal wire.

Using the mortar attachment, you can turn an ordinary drill into an efficient construction mixer. The kneading of building and finishing mixtures, which is carried out with the help of a mixer nozzle for a drill, is carried out not only quickly, but also with high quality. It is only important not to exceed the volume of the mixed mixture, so as not to reduce the efficiency of using such a device.

Speaking of what can be done with the help of additional equipment used complete with a hand-held electric tool, we should also mention the riveter attachment for a drill. The tool on which such a nozzle is installed must have a reverse function, and the rivet fixed with such a device can only be of the pull type.

The main functional part of the drill is the motor, which drives the electric shaft. In the future, the load is transferred to the actuators, one of them may be a cutter for a drill. The cutter represents a tool like a screwdriver or a drill. Depending on the configuration and width of the cutting part, recesses of various profiles, selections and grooves can be created in the body of the material being processed.

Features of working with a drill with a cutter

Milling involves the processing of material with a cutter installed in a fixed body of a power device. In this case, it is assumed that the speed is regulated on the tool, the depth of entry into the material being processed. But the array on which the action is performed must move. Such machines are called milling machines.

It can only be used as a router in some cases. The reason is the special accuracy of work, a large effort on the drive. The cutters for the drill are specially designed, taking into account the power and methods of regulating the device. Of great importance for work is the shape of the drill and its center of gravity.

Features of using a cutter for a drill:

• a change in the load vector can damage the gearbox if additional pressure is applied to the workpiece;
• the motor overheats, frequent rest is required;
• load on the plastic case can lead to armature skew and deformation;
• fastening in a cartridge with a horizontal axis of work is unreliable.

All this suggests that the drill as a milling cutter works in an unusual position for it and with uncharacteristic directions of resistance forces. Work with a milling nozzle for a drill, you need to slowly, with caution.

Woodwork

The tool is a shank for fixing in a chuck and a cutter, which is made of special steel. Initially, the cutter is sharpened for a specific operation. The tooling is made with strict precision to eliminate backlash. Sharpening and steel in hardness are selected according to the characteristics of the material being processed.

It is better to select the profile and depth of cut on a sample of material of similar hardness. In this case, the drill is installed in the clamps at the desired distance and the speed is selected corresponding to the work performed.

For attachment to a drill, only end mills with a shank are used. For long work without sharpening, it is better to choose cutters for plywood. They cannot be sharpened on their own.

A wood cutter for a drill differs in the type of processing:

• mugs - round the corners;
• V-shaped - make a sample in the body of the workpiece;
• disk and fold - create grooves;
• fillet - an internal groove on the edge;
• dovetail - connecting nodes for thorn-groove;
• edging - process the edges of the planes.

Cutters for wood are distinguished by their soft effect on the material in order to prevent chipping and hardening of the edge to brittleness.

Features of milling cutters with shanks for metal processing

Metal is a solid material with a uniform crystal lattice. It is processed rigidly, the main indicator is the speed of work.

Depending on the desired result, cutters for metal of various configurations are used for drilling:

• end;
• corner;
• cylindrical;
• disk;
• terminal.

End cutters are used for vertical processing of metal. More often they process a plane.

If the teeth are located on the end and side edge of the flat disk, it is possible to drill a recessed profile on the plane. This is how grooves and grooves are made. If you use not a disk, a cylinder with smoothly curved grooves, you can process a horizontal surface, remove a layer, smooth out irregularities. For each operation, a special cutter for metal for a drill is selected. In this case, you should be aware of the load on the motor and bearings, avoiding overheating of the tool.

The requirement for the manufacture of the cutter is stringent. The tool must work efficiently, keeping the sharpness of the cutting surface for a long time. Often, in order to save expensive carbide steel, the cutters are made prefabricated, the body is made of ordinary steel, and the teeth are made of alloys.

Cutters should be purchased only from reputable manufacturers. At the same time, check the quality of sharpening, the uniformity of the structure, pay attention to the material of the cutting edge. Particularly check the tightness of the prefabricated milling cutters.

The cutter, like any cutting tool, requires careful handling. The cutting edge does not tolerate heat, vibration, or misuse.

We process plastic with a drill with a cutter

A feature of plastic processing is its viscosity. When exposed to a cutter at high speed, the plastic first begins to wrap around the cutter, and then liquefies. Therefore, the selection of drills and the processing speed of each polymer causes certain difficulties. A plastic cutter for a drill is selected depending on the type of material:

• thermoplastics;
• thermoplastics.

From the name it is clear that thermoplastics become fluid under the influence of temperature, the chips of such materials are drained, with melted edges. Thermoplastics are not subject to softening when heated. Often this material is produced with reinforcement. Based on the properties of the polymer, cutters and processing mode are selected.

Thermosetting plastics are machined with multiple cutters while maintaining smooth processing. The depth of one cut should not exceed 2.5 mm. Otherwise, you can get the destruction of the treated surface. Taking into account the artificiality of the material, it is necessary to organize the suction of microparticles so that dust does not enter the respiratory organs of the worker.

Soft material should be cut with double-thread cutters at low speed so that the material does not “flow”. For sheet plastic, it is better to use compression cutters for edge processing.

Drilling concrete

If there is a need to process the structure with a concrete cutter for a drill, diamond crowns with external cutters are used. The cutter is unscrewed from the base, shank. The victorious layer cleans the hole well, provided that a powerful drill works in shockless mode. Such crowns are used to remove ceramic tiles from the wall, for fine cleaning.

The use of pobedite crowns for drilling is fraught with danger. The drill must be held strongly, expecting a jerk, as the density of the material in the wall can change, and the force of impact will create a blow.

Why do you need a drill on a magnetic bed

When developing a drill on a magnetic bed, they were guided by the problem of creating holes in multi-ton metal structures that cannot be moved. Such farms, like a large magnet, attract a pair with an opposite charge. The creation of a charged bed for a drill solved the problem of fixing a tool for drilling holes with high accuracy.

Drilling large holes in metal is performed with different nozzles, including the use of a drill bit for a drill on a magnetic bed. Typically, such a nozzle is used in the form of a hollow crown. Drilling with a drill on a magnet according to the marking is guaranteed to be accurate. As long as voltage is applied to the frame, the drill is held on the plane with a force of several tons per square centimeter. After turning off the current, the installation is moved to a new place easily, its weight does not exceed 25 kg.

A hole cutter can drill a hole in a structure up to 130 mm in diameter.
