The main functional part of the drill is the motor, which drives the electric shaft. Subsequently, the load is transferred to the actuators, one of which may be a milling cutter for a drill. The milling cutter represents equipment, like a screwdriver or drill. Depending on the configuration and width of the cutting part, recesses of various profiles, recesses and grooves can be created in the body of the processed material.
Features of working with a drill and cutter
Milling involves processing the material with a cutter installed in a stationary housing of the power device. In this case, it is assumed that the speed and depth of penetration into the processed material are regulated on the tool. But the array on which the action is performed must move. Such machines are called milling machines.
Can be used as a router only in certain cases. The reason is the special precision of work and the high force on the drive. Drill cutters are specially designed taking into account the power and methods of regulating the device. The shape of the drill and its center of gravity are of great importance for the work.
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;
- the load on the plastic body can lead to armature misalignment and deformation;
- fastening in a chuck with a horizontal axis of operation is unreliable.
All this suggests that the drill as a milling cutter operates in an unusual position and with unusual directions of resistance forces. You need to work slowly and carefully with the milling attachment for a drill.
Woodwork
The tool consists of a shank for fastening in a chuck and a cutter, which is made of special steel. Initially, the cutter is sharpened for a specific operation. The equipment is made with strict precision to eliminate backlash. Sharpening and steel hardness are selected according to the characteristics of the material being processed.
It is better to select the profile and depth of cut using a sample of material of similar hardness. In this case, the drill is installed in the clamps at the required distance and the speed is selected corresponding to the work being performed.
For attachment to a drill, only end mills with a shank are used. For long-term work without sharpening, it is better to choose cutters for plywood. You cannot sharpen them yourself.
Wood cutters for drills vary according to the type of processing:
- kalevki - round corners;
- V-shaped - make a selection in the body of the workpiece;
- disk and folded - create grooves;
- fillet – internal groove on the edge;
- dovetail - connecting nodes for tongue and groove;
- edge - process the edges of the planes.
Wood cutters are distinguished by their gentle effect on the material in order to prevent chipping and hardening of the edge to the point of brittleness.
Features of 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, metal cutters of various configurations are used for drilling:
- end;
- corner;
- cylindrical;
- disk;
- terminal
Face cutters are used for vertical metal processing. More often they process a plane.
If the teeth are placed on the end and side edge of a flat disk, you can drill a recessed profile on the plane. This is how grooves and grooves are made. If you use not a disk, but a cylinder with smoothly curved grooves, you can process a horizontal surface, remove a layer, and smooth out irregularities. For each operation, a special metal cutter for the drill is selected. In this case, you should remember the load on the motor and bearings, avoiding overheating of the tool.
The requirements for the manufacture of cutters are strict. The tool must work efficiently, maintaining the sharpness of the cutting surface for a long time. Often, in order to save expensive carbide steel, cutters are made prefabricated, the body is made of ordinary steel, and the teeth are made of alloys.
Milling cutters should only be purchased from well-known manufacturers. At the same time, check the quality of sharpening, the uniformity of the structure, and pay attention to the material of the cutting edge. Particularly check the tight fit of the prefabricated cutters.
A cutter, like any cutting tool, requires careful handling. The cutting edge does not tolerate heat, vibration, or improper use.
Processing plastic with a drill and cutter
A special 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;
- thermosets.
From the name it is clear that thermoplastics become fluid under the influence of temperature, the chips of such materials are draining, with melted edges. Thermoset plastics are not subject to softening when heated. Often this material is produced with reinforcement. Based on the properties of the polymer, cutters and processing modes are selected.
Thermoset plastics are processed with multi-flute cutters, while maintaining smooth processing. The depth of one cut should not exceed 2.5 mm. Otherwise, the surface being treated can be destroyed. 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 system of the worker.
Soft material must be cut with two-flute cutters at low speed so that the material does not “drip.” For sheet plastic, it is better to use compression cutters for edge processing.
Milling concrete with a drill
If there is a need to process the structure with a concrete cutter for a drill, diamond core bits with external cutters are used. The cutter is unscrewed from the base, shank. The pobedite layer cleans the hole well, provided the powerful drill operates in non-impact mode. These crowns are used for removing ceramic tiles from the wall for finishing cleaning.
Using pobedit bits for drilling is fraught with danger. The drill must be held firmly, expecting a jerk, since the density of the material in the wall may change, and the force of the impact will create a blow.
Why do you need a drill on a magnetic bed?
When developing a drill on a magnetic bed, we were guided by the problem of creating holes in multi-ton metal structures that cannot be moved. Such trusses, like a large magnet, attract a pair with an opposite charge. Creating a charged frame for a drill solved the problem of securing a tool for drilling holes with high precision.
Drilling large cross-section holes in metal is carried out using different attachments, including using a milling cutter for a drill on a magnetic bed. Typically, this attachment is used in the form of a hollow crown. Drilling with a magnetic drill according to the markings 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 easily moved to a new location; its weight does not exceed 25 kg.
A hole saw can be used to drill a hole in a structure up to 130 mm in diameter.
Not every home craftsman has a milling machine at hand. After all, this is a rather complex device, it requires a lot of space, and it costs a lot of money. But I really want to give wooden parts an attractive shape and provide a stylish design with the help of various shaped grooves and recesses.
A more affordable tool for many amateur craftsmen is an electric drill - a fairly compact device, easy to use and affordable.
The main purpose of this device is to drill and ream holes in various materials. But there are many homemade devices with which you can perform milling operations on wood and wood materials using an ordinary drill.
Below we will consider one of the possible options for such a device, almost entirely made of wood. Let's see what tools we need for this?
Required tools and materials
The drive for almost all the tools we use is a drill, for which we make a device for milling operations. We will need the following instrumental positions:- circular drill (“ballerina”);
- twist drill;
- feather drill (“perka”);
- core drill (“crown”);
- hacksaw for metal;
- sandpaper;
- milling heads;
- ruler and marker;
- clamps.
Making a device for milling with a drill
Without hesitation, let's get to work. We lay the blank board on a flat base. We fix the shank of a circular drill in the drill chuck and cut out two circles of the required diameter one after another (100-120 mm).
We place each of the cut circles on the mandrel in turn, fix it in the drill chuck, turn it on and use sandpaper to grind the forming parts of the wooden disks.
We secure the circles with clamps to a reliable base and, using a core drill, drill a hole in their center with a diameter equal to the size of the part of the drill body adjacent to the spindle (about 50 mm).
We also process the resulting holes with sandpaper.
We make another hole under the neck of the drill.
We mark one of the disks so that we get four identical cutouts, symmetrically located around the circumference.
Moreover, the cutouts should be limited by perpendiculars that do not intersect in the center of the circle. We cut out the marked elements with a hacksaw.
We fasten the circle with cutouts “on the edge” with clamps and on the horizontal shelves we drill successively recesses for the nuts and, as their continuation, through holes for the tightening bolts, respectively, using a spade and twist drill.
Next, use a hacksaw to cut this workpiece into two symmetrical parts (halves).
Using a pair of identical blocks of the required height and cross-section, as well as appropriate markings, we connect it with screws to the second circle.
First, we tighten the halves of the circle with the cutouts with bolts and nuts. We fix all the heads of the used hardware flush.

Bottom:
All that remains is to attach the device we just assembled to the drill, and in its chuck - the milling head, and you can easily and simply make any shaped grooves in wooden parts.
We insert the cutter into the chuck.
In order to make it easier and more convenient to work with our homemade device, it is better to screw wing nuts onto the bolts that tighten the “clamps” on the drill instead of ordinary nuts. Tightening and unscrewing wing nuts is undoubtedly easier and faster than standard nuts.
Also, work on the device will be simplified if, instead of spiral and spade drills, you use a combined furniture drill (it simultaneously drills a recess for the head and a through hole for the fastener rod).
Thanks to a large selection of different drill attachments, this versatile device can replace many other tools. For example, grinding discs eliminate the need to purchase a grinding machine, and an attachment for tightening screws and self-tapping screws will replace a screwdriver.
Using such snap-ins, you can perform the following actions:
- grinding;
- polishing;
- cutting;
- mixing;
- twisting;
- drilling holes of different diameters;
- milling.
When used correctly, the result will be of the same quality as if the work was performed using a special single-purpose tool. you can’t do without a drill with different attachments for a pigsty, rabbit cages and other outbuildings in the country.
Types of nozzles
All drill attachments are divided according to purpose:
- stops;
- for drilling holes, crowns;
- cutting, scissor attachments “Steel Beaver” and “Cricket”;
- for drilling at an angle;
- polishing and grinding;
- cutters for wood and metal;
- feather removal;
- sharpening.
A parallel stop is used to adjust the immersion depth of the drill; there are also special drill stands at the bottom for reliable fastening of the tool. In addition to the standard drilling function, the drill can be used to make blind holes, for example, for installing hinges in wooden furniture. In this case, a Forstner drill is used. The base of the hole is flat and its edges are absolutely smooth. Or use feather drills instead. 
Cutting attachments
Unlike an angle grinder, drill attachments for cutting metals work more delicately and do not deform the coating of the material being processed. The equipment is activated using the tool chuck on which it is installed.
For cutting metals, you should choose drill models with a speed of at least 2800 rpm.
Advantages of cutting attachments:
- smooth cut;
- comfortable work;
- easy to use and maintain, no adjustment required.
The “Cricket” drill attachment is a nibbler with two cutting heads. They are used for cutting thin sheet metal: profiled metal sheets, metal tiles, profiled or sheet plastic, as well as polycarbonate. “Cricket” is simply irreplaceable when erecting on a site. 
“Cricket” is used for sheets of materials with the following parameters:
- the thickness of the sheet steel should not be more than 1.5 mm;
- stainless steel up to 1.2 mm;
- aluminum, copper and plastic no more than 2 mm.
The cut after processing this nozzle always remains smooth, without jagged edges, and the coating is intact.
To make a high-quality and even internal cut, you must first drill a hole.
The nozzle matrix rotates, thanks to which you can work with both horizontal and vertical surfaces. The recommended number of tool revolutions for using this equipment is 3000 rpm, minimum 1500 rpm.
Also for cutting profiled sheet metal and tiles, the “Steel Beaver” scissor attachment is used. 
The principle of operation is similar to the previous nozzle; the cut occurs due to the frequent reciprocating movements of the punch, which bends the material and breaks it against the matrix. This equipment can be used to make curved and straight cuts. The minimum cutting radius is 1.2 cm. You can work with it at any angle (360°). Compared to the Cricket, the equipment is capable of cutting steel sheets of greater thickness - 1.8 mm. The main advantage of the nozzle is an even cut, and due to the absence of sparks, the protective coating of the material does not deform during operation.
Upon completion of work, you should carefully handle the sheet material, since the cut edge becomes sharp after processing.
Sanding and polishing attachments
Using drill attachments for grinding and polishing, you can carry out the following types of work:
- polishing metal, wood and glass surfaces;
- grinding of metal, parts made of it and other materials;
- removal of corrosion, scale, nicks and old coatings;
- polishing the edge of the glass.
Compared to special tools, these devices have a low price and can cope with a large number of different tasks, making any surface perfectly flat and smooth. In addition, they can be used to treat hard-to-reach places where it is impossible to use other tools. But due to their small size, it is difficult to perform a large amount of work with them.
When purchasing a drill attachment for processing wood or other material, you should carefully study the instructions. Since different types of equipment require different power and number of tool revolutions.
All polishing and sanding attachments consist of a rod on which abrasive material, such as foam rubber, felt, brushes or sandpaper, is attached.
The following types are produced:
- plate;
- disk;
- fan;
- drums;
- end;
- cup-shaped
Polishing devices are divided not only by type of design, but also by degree of rigidity: hard, soft, super-soft, embossed.
Cup
A cup attachment for a drill for sanding wood or other coatings consists of a rod for fastening in a chuck, and a cup-shaped body filled with hard or light bristles. Most often it is used to remove corrosion or old coating. Models with a soft polishing part are also available: foam rubber, felt or other similar material. The body is made of durable and lightweight plastic or metal. Soft drill attachments are most often used for polishing a car. 
Disc and plate
Disc devices, like cup devices, consist of a rod, a body and a grinding material. The main difference from the previous model is the direction of the bristles (steel wire, brass brush), it is directed from the center to the edges of the disc. They must be used carefully, as they can quickly damage the coating.
Drill disc attachments for polishing or grinding are made on the same principle as for grinding devices. But instead of threads, they are equipped with a movable or fixed rod for fastening in the chuck. Sandpaper is attached to them using Velcro.
Experts recommend purchasing plate attachments with a movable rod, rubber or with a soft and thick layer between the Velcro and the base. Because then you can adjust the angle of the drill and smoothly follow the contours of the material.
When working with a rigid plate, it is more difficult to control, and even with a slight tilt it will create a noticeable depression in the surface. As a result, you can completely ruin the material. Therefore, it is recommended to use them only with the tool firmly secured to the stand.
Fan (petal), drum and end
Sanding fan attachments for a drill are a small disk in the center, to the edges of which petals of sandpaper or other abrasive material are attached. This device is convenient for processing hard-to-reach places, internal cavities or grinding holes, as it can take any shape. They are fixed in the drill chuck in the same way as previous models, using a rod.
The drums are made in the form of a cylinder with a rod, covered on the outside with sandpaper. Unlike the disc attachment on a drill, the machining surface is located parallel to the chuck, and not perpendicular. They process wood, metal, and glass. Most often used for sharpening the end of glass. They are soft and hard depending on the purpose.
The end ones are a rod at the end of which the processing material is fixed in the form of a circle or cone. The attachments work on the principle of a file. Using them, you can increase the diameter of the hole, as well as remove jags and make the edges smooth.
Other attachments
The angle attachment on the drill allows you to make holes in places where it is impossible to work in normal mode. The angle can be adjusted or remain unchanged - 90°. Core bits are used for drilling large holes in wood, concrete, ceramic and tiles, metal and other materials. They are made of high-quality steel so that the holes are smooth, without chips or cracks.
The attachment for sharpening drills is a body with a leash and a sharpening stone inside. The sharpening holes have different diameters. Their number can reach 15 pieces. Mixer attachments are used for mixing various solutions, paints and other mixtures. Selected depending on consistency. There is also a special attachment for tightening self-tapping screws or self-tapping screws, but it should be purchased for drills equipped with a speed reduction function.
For poultry owners, a feather removal attachment has been developed for a drill for plucking poultry. It instantly and safely removes all feathers from the carcass. In this case, the skin and meat are not damaged. Before work, there is no need to first scald the carcass or treat it after plucking with a blowtorch.
The drill attachment for plucking poultry is easy to use; you just need to securely secure the tool and bring the bird to it. Made from easy-to-clean materials and takes up very little space.
For those who work with wood material, different types of cutter attachments are available. They allow you to make grooves of various shapes, process holes or remove defects. They are pointed and backed. 
Before working with any attachments, you should check the reliability of their fastening in the chuck and the material being processed. The drill must be held with both hands. During work, be sure to use protective equipment (gloves, goggles).
Homemade drill attachments - video
An electric drill is an indispensable tool that can be found in almost every home; it is more than a motor with a chuck and a comfortable handle. It is the drill chuck that is the device that allows you to use it with advanced functions. The only exceptions are stops designed to fix the drill and accurately set the position and direction of movement.
Classification of nozzles and devices
Additional accessories and attachments for the drill can be divided into several groups based on functionality.
Groups of attachments and accessories for drills:
- stops and clamps that allow you to accurately position the tool and limit the depth of the holes;
- stop attachments for forming holes at different angles and at precisely adjusted right angles;
- nozzles with cutting functions for metals, wood, plastics, and panel materials;
- polishing and grinding attachments, wheels, brushes, abrasive tools;
- whisks for mixing solutions, paints, plaster mixtures, adhesives;
- pumps driven by an electric drill.
This list may not include all categories of attachments and devices, since the choice is huge, and new devices appear constantly. They are produced not only by industrial enterprises, but also by craftsmen.
Stops, frames, guides, machines
In this category you can find several types of devices, the task of which is either to limit the displacement of the drill relative to the drilling axis, or to make its translational movement as precise as possible in direction.
The design of most stops consists of two guides, drill position clamps, a frame itself, or a socket for installing the tool.
The guides can be supplemented with return springs, which repel the tool in the absence of human effort. Some stops have worm-type movement and locking mechanisms designed to move the tool slowly or set it in a specific position.
Stops have two clearly divided categories - those fixed to the drill and those that fix the drill itself. The second ones, installed on a table or workbench, give the drill the function of a moving part, a carriage of a drilling or grinding machine. Craftsmen also manage to make lathes. These are very specific devices that are not always used in everyday practice of using a drill. Their acquisition must be clearly motivated - either you are a craftsman who makes a certain profit from the tool, or you are a collector or a lover of metalworking and turning.
The cost of stops varies widely, since there are many options for their design, level of complexity and functionality. The simplest device in this class is a parallel stop, which limits the depth of penetration of the drill into the material. Fixed machines are the most expensive part of this section, designed for professional use.
Advanced Drills
The main task of an electric drill is to drill holes, and the range of tools for this is very wide. In addition to conventional sets and single drills, in this class of devices you can find and use:
- Forstner drill with a centering point and wide side cutting surfaces. The tool allows you to make holes of small and medium diameter in wood without going through the material. Thanks to the tip, this drill can make holes for installing hinges, very precisely located in relation to the edges of the board;
- Spade drills for working with wood allow you to make wide, up to 60 mm, holes for installing fittings in solid and slab materials. The centering point and wide side stays are designed for precise recess positioning and limited depth. Drills have a characteristic flat configuration;
- crown attachment is a complex shaped tool for sampling material from solid wood and chipboard, fiberboard, concrete and metal. The robust, wide cutting surface with a distinctive profile works as a cutter or group of cutters that selects holes up to 100 mm in diameter. In the center of the nozzle there is a drill, which defines the first, centering hole and guides the entire nozzle;
- drills for wood, concrete, metal - a wide range of different configurations, including especially durable Pobedit drills for working with concrete. In this group you can also find attachments for vibration and impact machines, which are similar in functionality to hammer drills.
Regarding the cost and the need to have the tools from this list, we can say that the choice of options is very large. The most expensive in the category will be a complex attachment for making wide holes - this is a professional tool that is not suitable for every drill.
Drill bits - home or professional
Feather drills and Forstner tools belong to the semi-professional category - they can be purchased and kept in a set, but it is worth considering that such specific devices do not need to be used in everyday practice. They will be useful for those who like to work with furniture, carpentry specialists, and for assembling doors.
It’s worth having a set of regular and pobedit drills in your home all the time, and the more diameter options there are, the better. In an apartment with concrete walls it is extremely difficult to do without a Pobedit drill. Attachments for rotary hammers and impact drills are considered in two versions - professional for builders and repairmen with powerful rotary hammers, and for home use, designed to work with a drill of extended functionality.
Angle adapters for drilling in hard-to-reach places
In this group of devices, gearboxes are most often found - gear and friction units that change the angle of rotation through the use of an additional mechanism and its own drill chuck. These are a kind of extensions that are installed on the drill and hold the drill in its chuck, making it possible to get into tight places.
Here it is worth thinking about choosing a device according to your capabilities.
itemprop="video" >
The best option would be a nozzle with a variable angle, almost universal, which costs a little more than a fixed one, but makes it possible to get anywhere. To use such a gearbox, you will need a drill with increased power and good torque, but for a person who does all the housework himself, the device can be a good helper.
Cutting attachments for electric drill
In this category you can find at least two design options and possibilities for using devices for an electric drill - classic scissors for working with sheet materials and so-called “crickets”, which allow you to make even cuts and drill wide holes.
Scissor attachment
The scissors work reliably with steel up to 3 mm thick; they can be used to cut polycarbonate sheets, aluminum profiles, plastic, and roofing materials. The nozzle is selected according to force, the range for selection is wide, and the tool can be adapted to a professional powerful drill and to a home machine.
In a private house or garage, such a device will not interfere with an amateur craftsman, because working with sheet materials is always relevant. Powerful scissors will require the purchase of a drill with the appropriate parameters.
Cricket attachment or nibblers
A professional device for working with sheet and roofing materials, capable of cutting sheet steel up to 1.5 mm thick, stainless steel up to 1.2 mm, plastic, aluminum and copper up to 2 mm. The main advantage of cricket-type cutting shears is the ability to accurately cut sheets and drill holes of medium and large diameters.
The tool is indispensable for roofers who value not only precision and accuracy, but also high speed of work. Using a cricket requires certain skills.
Is it worth buying or keeping such a device in your home workshop?
Only provided that you know how to use it, and the tool itself is of high quality and expensive. A low-quality cricket will not give a good cutting effect, and you will only need to use it from time to time. The cricket makes it possible to perform artistic cutting of sheet materials.

Polishing and grinding tools for electric drill
This category consists of two large sections - polishing and grinding tools. These tools can be different in shape, since they can be used for working on surfaces, processing holes and finishing seams. Depending on the purpose, the material of the tool is selected.
Polishing accessories
Made from felt, felt, wool and foam rubber, sandpaper. Designed to bring surfaces, holes and seams to their final smooth state, giving a shiny effect.
Professional tools include attachments for processing holes and polishing discs - the most expensive ones, which allow you to bring various holes, including in car body parts, to the technologically required state.
Nozzles of this type are selected according to their main purpose and size. For a home workshop, a polishing brush is sufficient for finishing surfaces and seams. It is worth purchasing brushes of three sizes and degrees of hardness in order to be able to process surfaces made of different materials. The most common polishing attachment is made from medium-hard felt.
Grinding Accessories
These nozzles vary in design and base material to:
- abrasive fiber discs mounted on a support plate;
- petal heads made of sandpaper;
- carbide cutters for working on particularly durable materials with high precision;
- grinding stones for processing edges, seams, holes;
- abrasive polymer brushes for removing dirt from the surface of metal, wood, stone and other materials.
You can notice that in the group of tools there are exclusively professional products - these are cutters made of special hard alloys (aka cutters) and rod grinding stones. Their use at the household level is practically pointless.
In your home workshop and garage, it is worth having a set of flap brushes and several nylon brushes, as well as abrasive wheels with several grain sizes. A very important detail - when purchasing such devices, we must not forget that they are subject to rapid wear. Their cost is usually low.
Whisk attachments
Always presented in a wide selection. These tools come in a variety of shapes and sizes, as they are designed for mixing dry, liquid and viscous mixtures. Whisks are usually inexpensive, but you should choose them taking into account the work ahead - you can break the nozzle if you apply it to an excessively viscous solution.
Tools with characteristic vertical parts are suitable for working with dry mixtures; spiral and complex nozzles are designed for mixing solutions of varying densities.
For large-scale construction work, only a drill with a whisk will not be enough; in this case, it is better to use a construction mixer.
Pump attachments for electric drills
This is the most specific group of devices - such a nozzle can be used for pumping liquids and solutions, but provided that you have a powerful drill. The pump performance is selected according to the situation, so it is extremely difficult to talk about a specific application.
The price range in this group is very wide, because the pumps are produced by Russian, Chinese, and European manufacturers. It’s hard to say whether to buy a pump attachment for a drill for a home workshop. In a private home or country house, it may be needed in emergency situations, but we must not forget that the time of continuous operation of the drill motor is limited, and the pump will have to be stopped periodically.
At the end of the review, we must note that when choosing attachments, it is necessary to take into account the design, power and functionality of the drill, your own skills in handling the tool and the need to strictly observe safety measures!
Drill attachments, as well as attachments for this power tool, provide it with new functions and the ability to successfully solve various technological problems. Accessories for equipping a drill allow you to use it not only for drilling, but also as a mechanical saw, milling cutter, small lathe or even a pump for pumping liquids. Modern manufacturers offer a wide variety of attachments and attachments that make the drill truly multifunctional.
Of course, attachments and other accessories will not turn a drill into a device comparable in performance and processing accuracy to specialized equipment, but they can be used quite successfully to solve simple technological problems. It is very convenient to use elements of additional equipment of a drill to solve construction and repair problems, as well as many other issues related to maintaining housing in proper condition.
Varieties of devices for additional equipment of the drill
The most common drill attachment is a stop, which allows you to simply and quickly drill holes to the required depth. The design of the simplest stop device includes an auxiliary handle and the stop 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 produced both for tools used in construction and repair, and for wood drills.
Parallel stops, intended for use in conjunction with tools for construction and repair work, are installed on powerful drills, which are used to drill holes in concrete and brick building structures. This type of attachment consists of a stop with a scale and an auxiliary handle for the drill. Some rip fence models have a built-in suction unit for removing processing waste, which is connected to a vacuum cleaner.
Popular among home craftsmen are accessories for drills, with which they can be used to perform carpentry work. A drill equipped with such an attachment is, in fact, a small milling machine. Its design includes a vertical stand with guides along which a special basket with a power tool fixed in it moves. Of course, such a machine is not capable of providing the same accuracy and productivity of the processing performed as specialized equipment, but it is suitable for performing simple work in a home workshop.
A fairly large category among the elements of additional equipment for hand-held electric tools are attachments and attachments for drills, with which you can drill at an angle. This 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°) relative 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.
On the modern market there are widely available devices for drilling holes that allow you 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 router. Such devices are especially popular among home craftsmen who make their own furniture.
When using various working attachments on a drill for woodworking, you can perform many technological operations (in particular, side drilling of holes in products with a round or more complex configuration, requiring the use of special inserts). Some models of such devices are equipped with special suction units connected to a vacuum cleaner, with the help of which dust and small chips are removed from the treatment area. It should be borne in mind that even such functional devices do not allow turning a drill into a full-fledged manual milling cutter, which has the same operational capabilities, but provides higher accuracy and quality of processing.
Dust removal attachments for drills
No one will dispute the fact that using a drilling machine rather than a drill to form holes is much more convenient (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 devices are equipped with a vice for fixing the part during processing, as well as a frame along which such a vice 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 stand 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 drills are very popular, allowing them to be used as a wood lathe. Such equipment is fixed on the work table, and the drill itself acts as its drive mechanism. To install a drill into the design of such an attachment, a special stand and fastening mechanism are used.
Such attachments are available in various designs, with a different set of cutting tools and accessories, making it easy to realize the dream of many home craftsmen to have their own lathe. Of course, a lathe driven by a conventional electric drill cannot be compared with specialized equipment either in terms of service life or in the 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 wood turning work.
The most popular accessories for drills include attachments that allow you to turn such a tool into an electric sharpener or emery machine. Their installation does not pose any 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 plane knives. Thus, by using such devices on a drill for sharpening, you can not only solve many everyday problems with their help, but also save on contacting qualified specialists. Even those who have no experience in this area can successfully use such sandpaper, 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 an attachment for milling, with the help of which grooves are made in carpentry 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 precision processing, and to create a groove of the required width and depth, it is equipped with special adjusting elements.
In order to effectively use tools driven by a drill even in the most inaccessible places, you can purchase a flexible drive or an angle adapter.
The flexible drive and the angle attachment for 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 secured. When choosing between two such devices, it should be borne in mind that the flexible drive, from the point of view of processing hard-to-reach places, has greater capabilities than an angle attachment for a drill. The bending angle of such a drive is not limited to 90°, it can be any.
Examples of using angle attachments
The question of whether it is possible to use an electric drill as a drive for a pump intended for pumping liquids is not without meaning. To practically solve such a problem, you don’t have to come up with various homemade products, don’t rack your brains over making a reliable mount for a drill on the body of a standard pump, and don’t worry about which adapter to use. All these issues have already been thought through by specialists and implemented in the design of the pump attachment.
Such a pump for a drill, although not intended for long-term and intensive use, is capable of effectively solving many problems. In particular, it can successfully pump small volumes of both viscous liquids (such as oil or paint) and ordinary water. To change the pumping speed of the 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 and 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, ensures high accuracy of the processing performed.
The meaning of drilling templates is that their design includes the standard sizes and location of holes that are most often made in elements of furniture structures. Thus, there are templates designed for drilling holes for fastening 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 from the edge of the workpiece.
Types of drill attachments
Attachments used with drills are also used to expand the functionality of the latter. This includes, in particular, a range of drill attachments for cutting sheet metal. Such drill attachments for cutting metal can work as notching or nibblers. Even when used with a conventional drill or screwdriver, they demonstrate high efficiency. For example, such a drill attachment for cutting can cope with metal sheets up to 1.5 mm thick, 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 a jigsaw, like many other devices with which you can cut sheet metal, contributes to intense heating of the processing area. This may cause the protective coating applied to the surface of the sheet to burn. Some of the most popular drill attachments used for cutting sheet metal include devices called "Cricket" and "Steel Beaver", as well as attachments that look like tin snips but are operated by a drill or screwdriver.
Among home craftsmen, as well as those who professionally engage in car body repairs, grinding and polishing attachments for drills are very popular. The working body with which such grinding attachments are equipped can be a drum with sandpaper glued to its surface, as well as a felt or felt disk.
The material through which the drill attachment for grinding will come into contact with the surface being processed is selected depending on the nature of the technological task. Thus, a grinding tool, with which rougher processing is performed, is often made of an abrasive material of the appropriate grain size, and felt or felt is glued to the polishing tool. A brush attachment, installed in the drill chuck using its shank, is also used as a polishing tool.
The drill attachment for polishing a car can be used not only after body repairs have been completed, but also in cases where the owner of the vehicle wants to give it its original shiny appearance. If you want to save on purchasing grinding attachments for a drill, you can make such a device yourself. For this, a homemade wooden drum is suitable, in the central part of which the shank must be securely fixed. Using this structural element, such a device will be fixed in the drill chuck. Sanding and polishing with a drill using a drum like this can be done using materials such as sandpaper, felt and felt.
Power tool attachments used for cleaning products made of various materials work on a similar principle. Thus, metal and abrasive attachments, as well as a brush attachment, can be used to clean metal products. The brush is made of metal wire and allows you to effectively clean the surface of the product from dirt, rust and remnants of old paintwork. The brush itself, which is equipped with such attachments, can be located on the end or side of the device (it all depends on the tasks to be solved). Such attachments also differ in the material from which the brush is made. Such materials, in particular, can be polymer fibers or metal wire.
Using a mortar mixing attachment, a regular drill can be turned into an effective construction mixer. Mixing construction and finishing mixtures, which is done using a mixer attachment for a drill, is carried out not only quickly, but also efficiently. It is only important not to exceed the volume of the mixture to be kneaded, so as not to reduce the effectiveness of using such a device.
Speaking about what can be done with the help of additional equipment used in conjunction with hand-held electric tools, we should also mention the riveter attachment for the drill. The tool on which such a nozzle is installed must have a reverse function, and the rivet fixed using such a device can only be of the pull-out type.
