Thanks to great choice With a variety of drill bits, this versatile tool can replace many other tools. For example, grinding discs eliminates the need to purchase grinder, and a nozzle for tightening screws and self-tapping screws will replace a screwdriver.
With these tools, you can do the following:
- grinding;
- polishing;
- cutting;
- mixing;
- twisting;
- drilling holes of different diameters;
- milling.
At correct use the result will be of the same quality as if the work was done with a special single-purpose tool. you can’t do without a drill with different nozzles for, a pigsty, cages for rabbits and others outbuildings in the country.
Types of nozzles
All nozzles for drills are divided by purpose:
- stops;
- for drilling holes, crowns;
- cutting, nozzle-scissors "Steel beaver" and "Cricket";
- for drilling at an angle;
- polishing and grinding;
- cutters for wood and metal;
- removable;
- sharpening.
The parallel stop is used to adjust the insertion depth of the drill, there are also special bottom drilling stands reliable fastening tool. In addition to the standard drilling function, blind holes can be made with a drill, 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 they use feather drills instead. 
Cutting attachments
Unlike a grinder, drill bits for cutting metals work more delicately and do not deform the coating of the material being processed. The tool is driven by the chuck of the tool on which it is installed.
For cutting metals, you should choose drill models with a speed of at least 2800 rpm.
Benefits of cutting attachments:
- even cut;
- comfortable work;
- easy to use and maintain, no adjustment required.
The attachment for the Cricket drill is a nibbler with two cutting heads. They are used for cutting thin sheet metal: profile 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 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 notches, 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 it can work with both horizontal and vertical surfaces. The recommended number of revolutions of the tool to use this tool is 3000 rpm, the minimum is 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 tool can 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 rig is capable of cutting steel sheet thicker - 1.8 mm. The main advantage of the nozzle is a smooth cut, and due to the absence of sparks, it does not deform during operation. protective covering material.
At the end of work, be careful with sheet material, since the cut edge becomes sharp after processing.
Attachments for grinding and polishing
With the help of nozzles on the drill for grinding and polishing, you can carry out the following types works:
- metal polishing, wood flooring, as well as glass surfaces;
- grinding of metal, details from it and other materials;
- removal of corrosion, scale, chipping and old coatings;
- glass edge grinding.
Compared to special tools these devices have a low price, and can handle a large number of different tasks I make any surface perfectly even and smooth. In addition, they can be processed hard-to-reach places where other tools cannot be used. But due to not large sizes it is difficult for them to carry out a large amount of work.
When purchasing a nozzle for a drill for processing wood or other material, you should carefully study the instructions. Since different types of equipment require different power and the number of revolutions of the tool.
All polishing and grinding attachments are a rod on which grinding material is fixed, such as foam rubber, felt, brushes or sandpaper.
The following types are produced:
- plate;
- disk;
- fan;
- drum;
- end;
- cup.
Polishing devices are divided not only by the type of construction, but also by the degree of hardness: hard, soft, super soft, embossed.
Cup
A cup attachment for a drill for grinding wood or other coatings consists of a rod for fixing in a cartridge, and a cup-shaped body filled with hard or light bristles. Most often it is used to remove corrosion or old coatings. 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 nozzles on a drill are most often used for car polishing. 
Disc and platter
Disc devices, like cup ones, 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. You need to use them carefully, as you can quickly ruin the coating.
Plate attachments for polishing or grinding drills are made according to the same principle as for grinding devices. But instead of a thread, they are equipped with a movable or fixed rod for fixing in the cartridge. Sandpaper is attached to them with Velcro.
Experts recommend purchasing plate nozzles with a moving rod, rubber or with a soft and thick layer between Velcro and the base. Since then you can adjust the angle of the drill and smoothly follow the contours of the material.
When working with a rigid cymbal, it is more difficult to control, and even with a slight tilt, it will make a noticeable indentation in the surface. As a result, you can completely spoil the material. Therefore, they are recommended to be used only with a firmly fixed instrument on the rack.
Fan (petal), drum and end
Grinding fan nozzles on a drill are small disk in the center, to the edges of which the petals of sandpaper or other abrasive material are fixed. It is convenient to handle hard-to-reach places, internal cavities or grind holes with such a device, as it is able to take any shape. They are fixed in the drill chuck in the same way as previous models, using a rod.
Drums are made in the form of a cylinder with a rod, covered on the outside with sandpaper. Unlike a poppet attachment on a drill, the processing surface is parallel to the chuck, and not perpendicular. They process wood, metal, glass. Most often used for sharpening the end of glass. They are soft and hard, depending on the purpose of the appointment.
The end ones are a rod, at the end of which the processing material is fixed in the form of a circle or cone. Nozzles work on the principle of a file. Using them, you can increase the diameter of the hole, as well as remove notches and make the edges smooth.
Other nozzles
An angled drill attachment allows you to make holes in places where it is impossible to work normally. The angle can be adjusted or be fixed - 90 °. Drill bits are used for drilling in wood, concrete, ceramic and tiles, metal and other materials of large holes. They are made of high quality steel so that the holes are smooth, without chips and cracks.
The nozzle for sharpening drills is a body with a leash and grindstone inside. Sharpening holes are different diameters. Their number can reach 15 pieces. Mixer attachments are used for mixing various mortars, paints and other mixtures. Selected depending on the consistency. There is also a special nozzle for tightening self-tapping screws or screws, but it should be purchased for drills equipped with a speed reduction function.
For bird owners, a pen-removable attachment for a drill for plucking birds has been developed. It instantly and safely removes all feathers from the carcass. In this case, the skin and meat are not damaged. Before work, it is not necessary to pre-scald the carcass or process it after plucking with a blowtorch.
The nozzle on the drill for plucking birds is easy to use, you just need to fasten the tool with high quality and bring the bird to it. It is made from easily washed materials and takes up very little space.
For those who work with wood material, nozzles cutters of different types are issued. They allow you to make grooves various forms, machine holes or remove defects. They are pointed and backed. 
Before working with any nozzles, you should check the reliability of their fastening in the chuck and the material being processed. The drill must be held with both hands. Be sure to use protective equipment (gloves, goggles) while working.

Nozzle-scissors on a drill"Steel Beaver"
A classic drill attachment for cutting metal tiles and any flat sheets from metal in the form of a freely rotating shaft in a bearing with a fixed eccentric, it works on the principle of a crank mechanism with the difference that energy is supplied here for rotation.
A complete cutting tool support part located on the frame, and movable - connected to the eccentric. It is the movable part that performs reciprocating movements during the rotation of the shaft. A mandatory element of the design is the handle, which is fixed perpendicular to the axis of rotation of the spindle. During the increase in load, a reactive torque occurs, due to which the drill advances relative to the nozzle.
It should be remembered that the tool must be placed strictly vertically relative to the workpiece when making a cut. Failure to do so may result in damage to the product and injury to the operator.
The device resembles metal scissors. The drill attachment is used for cutting flat products or profiled sheets with large radius bends. The cutting line is easily controlled. When the tool is running protective layer coating is not burned, which eliminates the formation of sparks and the likelihood of burrs. You can perform continuous cutting of products of any length.

HPM is an analogue of the actuating mechanism of punching shears. It works on the principle of a die cutter. The source of movement for it is the electric motor of the drill. The rotational movement from the cartridge is transmitted to the connecting rod-crank mechanism of the nozzle. This mechanism converts it to reciprocating and sets the punch in motion. The latter creates a cutting line of the desired shape and width.
Taking into account the coincidence of the schemes of operation of the actuating mechanism of shears and HPM, we will consider the principle of operation of the latter using the example of the kinematics of electric punching shears.
Explanation for the figure:
1 - matrix holder;
2 - matrix;
3 - punch;
4 - slider;
5 - connecting rod;
6 - crank shaft;
7 - electric motor.
The rotation from the electric motor 7 (through a two-stage cylindrical gearbox) is transmitted to the shaft of the crank mechanism 6. From it, the reciprocating motion through the connecting rod 5 is reported to the slider 4. The punch 3 is fixed in the slider, and the matrix 2 is in the die holder 1. The material to be cut is placed into the gap between the die and the punch. When the latter moves down, it is incised and moves in the right direction (possibly in any direction). Successive notches form a continuous cut line. The cut workpiece is separated along it.
What metal can be cut
The following metals can be machined with HPM:
- aluminum. Thickness ≤ 2mm;
- copper, brass, sheet iron, pure zinc and steel coated with zinc - thickness up to 1.5 mm;
- stainless steel, up to 0.8 mm thick.
What determines the quality of the cut
Enterprises, taking into account market demands, produce NRMs that operate on the same principle, but, of course, various designs. They have different specifications:
- some NRMs are designed for strictly defined grades and sizes of materials, have simple design higher reliability and lower cost. Devices of this group provide higher quality products. But if you need to cut various metals, you should purchase a whole line of such devices. Therefore, they are used in the mass processing of metal of the same size;
- others are universal nozzles"for all occasions". They are more complex, more expensive and the quality of processing on them is somewhat worse. For getting best quality products, you should choose a tool with a set of dies and punches.
You need to work with nozzles carefully so as not to damage the surface of the sheets. It is very important to choose the right number of revolutions of the drill. This will allow you not to crush the edges of the metal, and they will turn out sharp. For example, for metal of small thickness it is better to use a drill with a speed of 2700 ... 3000 rpm. Proceed directly to the cut should only be when the armature of the tool has gained optimal speed.
Nozzle "Cricket" for cutting metal
Very popular device HRM "Cricket". Consider it using the example of the Enkor 14210 model, which can be used in conjunction with any drill.

- maximum thickness of the processed sheet, mm:
- steel - 1.8;
- stainless steel - 1.2;
- copper and aluminum - 2;
- weight, g: 400.
SPARKY nozzle
Cutting metal with a screwdriver or drill: advantages and disadvantages
Compared to other equipment, HRM has a number of advantages:
- high quality cutting with the ability to cut any shape;
- high economy. It is explained by the fact that consumables are not needed;
- high performance;
- the ability to process many grades of metal;
- comfortable operating conditions;
- the ability to work in conjunction with an electric or pneumatic drill (a screwdriver is allowed);
- does not require expensive maintenance.
However, despite all the advantages of NRM, it has disadvantages. To ensure high quality cutting, certain skills and dexterity are required. In addition, it damages adjacent sections of the workpiece and often becomes the root cause of corrosion.
What not to expect
In general, you should not think that HPM will always be a replacement for several tools. Unfortunately, its power is incomparably low compared to electric scissors. professional level. This attachment is not designed for effective processing of thick metal sheets. It should be remembered that the maximum that it can cut is a steel sheet 2.5 mm thick. In the conditions of professional and, moreover, industrial metal processing, a more powerful specialized tool, among which the Bulgarian stands out. This tool is capable of effectively processing metal workpieces of almost any thickness.

Some fixtures are easy to cut with flat sheet steel, others are great for stationary work, and the third, being household tool, barely cope with the task of cutting drywall profile. The only exception is one device - cutting shears, one of the options for which is the attachment for the cricket drill, which will be discussed in this article ..

How nibblers work
It is quite simple to imagine the work of nibblers - in fact, it can be compared with a chisel that makes breakdowns in metal with great frequency. Another comparison is the modern electric jigsaw, in which the standard saw blade with teeth is replaced by a punch rod (chisel). This principle of robots, combining a punch tool and a jigsaw, reveals wide opportunities and allows you to use the tool of this type even for figured cutting of sheet iron. It is for this reason that modern builders use a "cricket" for cutting:
- profiled flooring;
- any smooth steel when it comes to large volumes of work.
These are not the only reasons why the cleaver drill attachment has become widespread in the field of construction and repair.

Benefits of this tool
Another significant advantage of the cricket is its careful attitude to the protective and decorative coating or metal tiles. Punching through the material, it not only does not injure it along the edges of the cut, but, on the contrary, rolls it, thus protecting the end of the cut from corrosion. As a result, the metal lasts much longer.
Additionally as an advantage cutting metal nozzles for a drill, the following points can be distinguished.
- High productivity – a 1 m long cut can be completed in less than a minute. Yes, the grinder cuts faster, but unlike the nozzle, it burns the protective and decorative coating.
- What is the ability to overcome almost any obstacle. The wave and various bends are not a problem at all - you can direct the movement of the cutter not only left and right, but also up and down.
- According to the manufacturers, this tool is able to easily handle metal up to 2 mm thick, which is quite enough to work with roofing materials.
- The cost of the instrument can be called purely symbolic. It is at least five times lower than the price of professional cutting shears with built-in electric drive.
As for the shortcomings, the most significant is only one - it is almost impossible to achieve a perfectly even cut. In principle, it is not needed, since the edges in most cases are covered either by another sheet of metal or by special elements. If you try hard and come up with some kind of guide, then this problem can be solved.
Safety precautions when working with a "cricket"
In addition to the risks of cutting yourself on the edges of sheet iron, there are a couple more points that you need to beware of when working with a perforated drill bit. These are shavings - small and, most importantly, sharp fragments of metal in the form of a crescent. They can cause very serious trouble.
- First of all, the shavings easily pierce into the legs, and this may not even be felt on hardened feet. Then suppuration begins and all the ensuing consequences. It is best to work with the tool in closed shoes.
- The second point is, or rather, its impeller, which serves to cool the electric motor. Penetrating into the air intake hole, small metal crescents quickly disable the power tool. There is only one way to protect the drill - to pack it in a mesh material (for example, nylon tights).
In addition, we should not forget that small chips scattered around the yard quickly corrode, and if it remains, for example, on paving slabs, then rust eats into it and spoils the appearance of the coating. Timely cleaning of the workplace solves almost all issues.

What to look for when buying a "cricket"
Almost all tools of this type have the same design and work on the same principle - no additional options they are not supplied, and additional devices are not provided for them. Everything is simple - including the choice, approaching which you need to pay attention to just a couple of points.
In principle, decide for yourself what is best for you - cheap and cheerful or expensive, but for a long time. From practice, I can only say one thing - my first nozzle from Sparky worked in intensive operation without repairs and Maintenance within five years. By and large, we are not talking about such big money - a professional nozzle can be purchased for about 30-50 dollars.
In conclusion of the topic, the “cricket” drill attachment, it remains to add only one thing - to remind you that it is possible to extend the life of any tool through proper care of it. Clean your "breadwinners" at the end of work and control them technical condition every self-respecting master should. Naturally, you should not forget about the careful attitude to the tool - hammering nails with a nozzle and generally using it for other purposes is simply wrong.
