Drill attachments have turned this tool into a universal assistant. Thanks to these removable devices, you can not only make holes, but also cut building materials, mix mixtures evenly, and also treat the surfaces of products made of plastic, wood, metal and concrete. This article describes the main types of nozzles, their characteristics and scope of application.

Thanks to a variety of attachments, the drill turns into a universal tool

Types of nozzles

Grinding attachments for drills differ in shape and material, but they all have a common part - this is a cylindrical rod that is clamped into a chuck. An abrasive or grinding material is attached to the rod in one way or another.

The most common grinding attachments for drills are:

• End - in the form of cylinders, cones and other figures of rotation made of hard abrasive.
• Cup brush or soft, cup-shaped material.
• Plates - made of plastic or rubber with a fixed piece of sandpaper.
• Disc - metal or soft.
• Fan-shaped with strips of sandpaper fixed in the shape of a fan.
• Soft in the form of discs for polishing.
• Drums with sandpaper.

Cup attachment

There are other designs of grinding attachments for drills, some are designed specifically for grinding the surface of parts with particularly complex shapes.

Angular attachments for drills stand apart. They do not have a working element, but serve to change the plane of rotation of the shaft, by 90° or by an arbitrary angle from 0 to 90°. At its end there is another cartridge into which the usual nozzle is clamped. This device allows you to work in hard-to-reach places. When installing an angle attachment on a drill, it is important to carefully check its attachment to avoid personal injury and damage to equipment and materials.

Advantages and weaknesses

The main advantage of the device is to expand the functionality of an already purchased tool. Additional surface finishing capabilities do not require the purchase of expensive specialized equipment.

Advantages of a drill attachment compared to specialized equipment:

• high-quality grinding of hard-to-reach places;
• ease of working with small parts;
• cost savings;
• opportunity to do it yourself.

But there are also disadvantages:

• not as convenient to work as with a special tool;
• for high-quality grinding you need to acquire the skill;
• lower productivity;
• Rotation speed adjustment is often required.

If the amount of work is small, then the advantages far outweigh their disadvantages.

Centrifuge-based plucking devices

A device for plucking poultry, operating according to the principle of a centrifuge, is essentially a container of a predominantly round shape, with pincers attached to the inner side surface at the bottom. The bottom of such a container rotates during plucking, which ensures constant contact of the loaded poultry carcasses with the beating fingers. During the process, the bird quickly frees itself from the feather. In order for such a device to work more efficiently, water is supplied to its internal part during plucking, which, even today, washes away already plucked feathers and does not protect bird carcasses from damage.

Quill centrifuges are available in various designs

Based on the dimensions and technical characteristics of the centrifuge plucker, this device can be used for processing poultry carcasses of various sizes. Thus, small devices are suitable for plucking chickens, quails and ducks, and larger pluckers, which consume more than just electricity, are used for processing the carcasses of geese and turkeys.

It is advisable to purchase machines that operate according to the centrifuge principle for small farms; other types of devices are used to mechanize the plucking of poultry carcasses with your own hands.

How to use attachments

The main areas of application for drill attachments are as follows:

• cleaning surfaces from rust, old paint residues and other contaminants before painting;
• polishing metal surfaces;
• polishing paint and varnish coatings;
• polishing glass or plastic (for example, car headlights);
• glass edge grinding;
• cleaning of metal parts after welding;
• grinding surfaces in hard-to-reach places.

Polishing the surface using a nozzle

In addition to grinding, special devices are also used for cutting thin sheets of metal and for plucking bird feathers.

Types of materials for making nozzles

Materials for the working body vary greatly in softness, elasticity and abrasive grain size. The main ones are:

• Sandpaper. They vary greatly in hardness, graininess and water resistance.
• Soft materials. Serve for polishing and fine finishing.
• Grinding stones. For rough surface treatment and correction of defects.

Grinding stone

The variety of materials and shapes of devices allows you to choose the most suitable one for each specific operation. Thus, a drill attachment coated with diamond powder will allow you to polish surfaces made of the hardest materials, and miniature attachments are suitable for finishing jewelry.

Drilling bits

Since the main purpose of a drill is to drill, and for drills with a screwdriver function, to screw in and unscrew self-tapping screws, there is a wide variety of attachments for this: from simple stops to limit the depth of drilling, to high-tech platforms for perpendicular drilling and drilling at a given angle.

Nozzles in this direction also include extensions of various designs and adapters:

• with axis offset;

• angular, both with a given angle of inclination and with a variable one;

Cutting attachments

Special drill attachments for cutting thin sheet metal, unlike the widely used grinder, make a more accurate cut and practically do not deform the sheet coating. This is especially important when cutting profile sheets for a fence or metal tiles for a roof. In addition, the device allows you to rotate the cutting line at large angles and along a minimum radius, which is simply irreplaceable when constructing a roof of complex shape.

The device is installed on a drill chuck and is driven by the working shaft. To ensure reliable operation of such a device, the rotation speed of the chuck should be from 2800 rpm, power - from 400 watts.

Drill attachments for cutting

Special attachments for cutting metal have the following advantages:

• smooth cutting line, without burrs and notches;
• any configuration of the cut out piece of sheet;
• does not damage the anti-corrosion coating of the sheet;
• ease of use.

Cutting devices can handle ferrous metal up to 1.5 mm thick, non-ferrous metals and plastic up to 2 mm thick.

Tips for use

Do you use drill attachments?

Constantly! I want to try

Different materials and tip types require specific grinding speeds. It corresponds to the number of revolutions of the tool. Therefore, for efficient operation, you should choose a drill with a wide range of motor speeds.

The simple structure of many equipment elements allows you to make them yourself. This is especially true for drum and soft tips, as well as disc models with attached sanding sheets.

For the convenience of performing tasks, you can also create a special holder that fixes the drilling unit parallel to the table, which will allow you to use it as a machine for sharpening and grinding.

A large assortment of various accessories for drills helps you save on the purchase of expensive devices that perform similar functions. This allows you to perform a wide range of tasks at home using one device.

Sanding and polishing attachments

Drill attachments for grinding and polishing allow you to perform a wide range of jobs. The main ones are:

• cleaning parts before painting or welding;
• grinding and leveling surfaces;
• final finishing and polishing of surfaces made of metal, wood, plastic or glass, as well as paint and varnish coatings;
• processing the glass edge after cutting.

They allow you to avoid purchasing expensive specialized equipment. It is worth remembering that with a large volume of work, the drill will not be able to provide the required level of performance and will wear out quickly, since it is not designed for constant loads perpendicular to the axis of the working shaft.

Drill attachments for grinding and polishing

Devices for grinding and polishing differ not only in the shape of the working body, but also in the degree of rigidity of its material by:

• hard;
• soft;
• super soft;
• embossed.

It is impossible to complete the grinding and polishing operation from start to finish with just one device. Your home workshop should have a set of such devices.

Polishing attachments for screwdrivers: purpose, selection and operation

The modern equipment market offers a wide variety of tools to perform almost any job in the comfort of your home. This approach helps to save significant money and not doubt the quality of the result. Such work includes grinding and polishing of any materials.

Sanding is necessary to make the surface smooth or prepare it for painting. This is the process of removing small irregularities from any surface. Polishing in simple words can be described as the process of rubbing a surface to a shine.

At home, such work is most often carried out when processing metal, in particular, a car body for painting. In this case, sanding precedes the application of a layer of paint to the metal, and polishing allows you to see the result in the best possible light.

However, there are other types of work:

• cleaning metal from corrosion;
• descaling;
• removal of old coating;
• removal of sagging (in concrete).

To perform such work, you need not only a polishing or grinding wheel with various attachments, but also a drill or screwdriver. Preference is often given to the latter, since the tool has more compact and convenient dimensions, as well as the ability to charge from batteries.

This option allows you to perform the necessary work outdoors without worrying about the lack of outlets. Having dealt with the tools, you can move on to considering the types of attachments for it.

Regardless of the type of material being processed, attachments perform 3 main functions: stripping, grinding and polishing.

These operations can be performed with the following materials:

• tree;
• concrete;
• ceramics;
• granite;
• glass;
• metal.

Types of nozzles also differ in quality and price. These criteria depend entirely on the manufacturer. The more famous the brand purchased, the higher the price, and usually the better the quality. Well-known manufacturers try not to spoil their good reputation by reducing the cost of production in favor of short-term profits.

Screwdriver attachments are distinguished by the type of material to be worked with and the type of coating of the device itself.

Nozzles are divided into:

• plate;
• cup;
• disk;
• cylindrical;
• fan;
• soft (can have different shapes);
• end

Plate attachments can be called universal. They are attached to the cartridge using a special small metal pin located in the middle of the circle. They produce fixed and adjustable products.

The upper part of such a device is covered with Velcro, so special wheels of sandpaper with different grain sizes can be easily changed. This is the main advantage of this attachment, since there is no need to buy a more expensive product.

You just need to buy a set of sandpaper you need.

Cup attachments are also often used when working with various materials.

They are a plastic recessed round base, on which pieces of wire of the same length are attached along the perimeter in several rows.

This device is very similar in appearance to a cup, which is why it got its name. This attachment is used for rough grinding work.

Disc attachments for grinding are derivatives of cup attachments, with the only difference being that in this type there is no cavity in the middle, and the disc on which the wire is attached is metal. The wires in such a product are directed from the center of the device to the edges, which makes the nozzle flatter. It is great for sanding areas with a small access perimeter.

Cylindrical products have a shape very similar to a drum, onto the ends of which tape sandpaper is attached. The body itself can be made not only of hard material, but also of soft one. The fastenings of the abrasive belt are also different.

It can be fixed using the maximum expansion of the nozzle itself or by bolt connections, which, when tightened, create the necessary tension. Such devices are intended to work inside hollow products such as the inside of pipes.

These attachments also perform well when processing the edges of glass sheets.

Fan products are disposable, as they initially consist of sheets of sandpaper attached to a disk. They are designed primarily for work in the interior of small recesses and pipes.

Such a nozzle is expensive compared to simple abrasive paper, but often it is impossible to grind with other devices.

Therefore, it is advisable to have this type in your home set in several variations: with larger and smaller crumbs.

Cup

In a cup nozzle, the working body has the shape of a bowl, on which more or less rigid bristles made of wire or plastic are attached. It is used for cleaning surfaces from rust, solid contaminants, welding slag and remnants of old paintwork.

Cup attachments for drill

There are also soft cup attachments with a working body covered with felt or foam rubber. They are used for polishing painted surfaces.

Using it requires developing a certain skill - when the axis of rotation deviates from the vertical or when the drill is held weakly, the cup has a tendency to move to the side, which can lead to damage to the polished surface or grinding of areas not intended for processing.

Disc and plate

Disc grinding attachments are similar in design to cup ones, but the wire or plastic bristles in them are directed not forward, but to the sides, in a plane perpendicular to the direction of rotation of the shaft. They must be used with caution, as they can damage the sanded coating.

Disc attachment

The plates consist of an elastic plate, to which it is attached with glue, double-sided tape, Velcro (Velcro), or a circle of sandpaper is clamped in the center. The edge of the plate can be curved, which allows you to bring the sandpaper to the surface at different angles and process hard-to-reach places.

Disc ones allow, among other things, the use of abrasive and cutting discs from angle grinders (grinders). They are attached to the shaft through a centering adapter.

In order not to damage small parts, it is better to secure the drill in the machine and bring the part to the disk, holding it with your hands or clamping pliers.

Homemade accessories for drills with your own hands

For household repairs and work on a summer cottage, various power tools are used. Specialized additional instruments and devices are produced for them, many of which can be made with your own hands.

It is better to get complex industrial devices ready-made, but workbenches, tables, attachments and almost everything else can be made without the help of others. Handmade devices for power tools can be adjusted to the required technical conditions.

Classification of devices for power tools

Do-it-yourself power tool accessories are usually systematized into the following categories:

• Tools and attachments for processing. These are hand-held devices, which include grinding attachments and bars for grinders and drills.
• Devices for modifying the position, mounting a certain cutting angle, drilling and the rest. These are the main surfaces, standards, guides. They can have different external types, often made of metal or wood.
• Dust removal devices. Similar devices are used to remove sawdust, dust, and shavings from the working plane. It is not so difficult to make such devices with your own hands; as a rule, pre-existing fan holes in the equipment are used for mounting.
• You assemble grinding attachments, structures or bars designed for surface treatment with your own hands. For example, to polish a wooden surface or clean an alloy, you can use a wooden plate with a handle on top. Sandpaper of the required grain size is fixed on its working side. The platform model can be anything, it is only important to choose the right abrasive material.

Diagram of the milling table device

Attachments for power tools vary, but sometimes they are large scale, as is the case with milling machines and saws.

It is recommended to choose an improved table that will contain everything you need without exception for comfortable and non-hazardous work. The most common type is a milling table, made in the form of a large board with an opening for a router and a guide board.

The scale of the worktop can be different, everything without exception depends on what kind of work will be carried out. The most ideal type is a table with legs of the required height. And the working and guide boards are made from chipboard sheets. In this case, vices and clamps can be taken into account on the surface.

It is generally better to make table legs replaceable and provide a backup set.

Workbenches for power tools

To work with numerous devices, you will need to improve your workplace. For a home workshop or a car garage, a small, compact and universal workbench may be necessary.

It is not so difficult to make it without the help of others; you just need to specifically improve your choice of what functions it is needed for.

In general, it is more correct to make a workbench that can be used at any height, including on a table.

Then it will be possible to position the power tool comfortably and change its position if necessary.

For work, it is recommended to use various hard woods; a common material is maple, which is easy to process and yet has the required hardness and strength.

To register on the table, it is possible to attach comfortable legs or clamps to the installation. A workbench requires a vice; they are often used in work, which guarantees an improvement in its quality.

Drill attachments

During operation, the drill may need various attachments. They make it possible to simplify work, make it simpler, more comfortable, and faster. A huge number of homemade products are used for the drill, which numerous manufacturers today have taken as the basis for the study of specialized kits. The list of devices that you can make with your own hands is huge.

Accessories for power tools:

• Limit attachments. At the time of repair and construction work, it will be necessary to make holes of the required diameter to a precisely specified depth. Directly for this purpose, a fairly elementary nozzle is used, which consists of 3 elements. It can be done with your own hands, and the characteristics of the holes can be easily and quickly changed as needed. The first part of the device is a clamp for holding it; it is installed directly into the block housing of the device. This kind of clamp has 2 holes; guide stops in the form of metal rods of 6 millimeters are inserted into them. The rods are bent if necessary. During operation, the required angle of inclination of the drill is exposed in order to create holes with the set parameters. Drilling depth limiter
• Circle cutters are a specialized device that in appearance resembles a huge compass. The nozzles are made from metal rods. The vertical lobe serves as a stop; at its end there is a specialized thickening. The horizontal part is attached to the vertical part, on one side of which a comfortable handle is made, and on the other side a ring is welded. The diameter of the fastening ring should be provided for the device so that the electric drill does not slip out and stays tightly in it during operation. It is generally better to attach a rubber ring from the inside, which can help make the fixation more reliable.

Various accessories for power tools are needed in order to make the work more convenient and simpler.

It is not always possible to buy such devices, of course, and they are often only needed for a couple of times. For this reason, it is much easier to do them without the help of others, spending not so much time.

Drill holders: design. How to make it yourself?

Anyone who has worked with a hand drill knows how difficult it is to maintain a strict vertical line. The slightest deviation can lead to breakage of the drill. To avoid this problem, it is recommended to use a vertical drill holder. Such a machine is available in every locksmith workshop.

Fan, petal, drum and end

Fans resemble a lady's fan in shape, have a small disk in the middle, and the sandpaper is attached to it not in a solid piece, but in overlapping petals. This design is capable of significant changes in shape, which makes it possible to process the most inaccessible places, especially cavities and internal surfaces.

Fan nozzle

Drum ones resemble the paddle wheel of a pedal boat and the direction of the petals differs from the fan ones - they are perpendicular to the plane of rotation of the disk. They are used for processing hard materials, most often for grinding the edge of glass after cutting.

In the end type, an abrasive in the form of a cylinder, disk, cone, bowl or other body of rotation is attached to the end of the rod. They work similar to a grinding wheel. The devices are made small in size to make them easier to balance and to be able to get to hard-to-reach places.

Other types of attachments

In addition to the most common grinding and polishing attachments, there are other types of attachments. This is the already mentioned angular one, as well as:

• Sharpening for drills. It has a drill feed mechanism and a sharpening stone inside, and holes for drills of various diameters are provided on the outside.
• Mixer for mortars.
• Feather remover for poultry or wild birds. It is a disk with radial rubber fingers from 5 to 10 cm long. Removes the feather without damaging the skin and meat. Particularly convenient for hunting, fishing and hiking.
• Wood cutters. They allow you to decorate products made of solid wood or MDF with relief patterns, grind grooves, drill holes, including large diameters, and eliminate some defects.

How to make an awl from an old bat

In the same way, you can make a small awl, which is useful for making holes in plastic and other materials.

The analogy for making an awl is simple:

• First you need to sharpen the screwdriver bit on a sharpening machine;
• Then you will need to take a piece of a block and make a handle for an awl from it;
• Using a piece of metal, you need to make a square hole in it for installing a ground bit.

You can also simply drill a hole in the handle and glue a homemade awl into it. This homemade product can be used both for its intended purpose and as a scriber.

Homemade drill attachments

In addition to the natural desire to spend less, home craftsmen are often driven by a desire for knowledge and self-expression. A couple of such projects for making devices from scrap materials are given below.

Homemade nozzle based on a car valve

Based on Automotive Valve

A good set can be made based on valves from a car engine. These parts are distinguished by high strength, precision manufacturing and excellent balancing.

The flat surface of the valve should be thoroughly degreased, and the head of the required shape should be secured with glue. Heads can be made from wood, thick rubber or hard foam. On a round sheet of sandpaper, draw a circle with a diameter equal to the diameter of the head, and make cuts from the edge to the intended circle. The central part is glued to the base, and the petals are wrapped on the back side of the head and glued to it or secured with construction brackets.

Simple screw device

If you may not have a car valve at hand, then a long screw, a couple of washers and a nut can be found in any home workshop.

Simple screw device

Sandpaper should be cut into squares and a hole should be made in the center, 4-5 of these squares should be put on the screw and clamped with a nut between the washers.

You will get the simplest attachment for a fan-type drill. The screw is clamped in the chuck, and you can clean hard-to-reach places.

The thread will soon be jammed by the drill chuck, in which case the master takes the next screw from the box.

Polishing device

The previous design is taken as a basis, but a circle cut from felt is clamped between the washers. To ensure better polishing, the felt is rubbed with GOI paste.

Homemade devices cope well with relatively flat surfaces; for surfaces with complex terrain, you will have to use store-bought ones.

DIY polishing device

What can you make from old screwdriver bits?

If you cut off the tip of the bit and then sharpen it on a sharpening machine, you can make a straight slotted screwdriver with your own hands. This screwdriver can be inserted directly into a screwdriver and can be effectively used for tightening various hardware.

It must be said that if the bit was good, but simply wore out over time, then a slotted screwdriver made from it will be no worse. Thus, you can breathe a second life into old screwdriver bits, spending no more than half an hour on everything.

Well, if you often have to drill metal products, then you simply cannot do without a center punch. A corner is a device that allows the drill not to slide on the metal, and allows you to make a hole in the right place. Of course, you can buy a ready-made punch for metal, but why spend extra money if you can make it from an old screwdriver bit.

To make a punch, you will need a sharpening machine, or, in extreme cases, a grinder with a disk for cutting metal. All you have to do is grind down the edge of the bat and make it sharp. It is also necessary to sharpen the side of the bit so that it becomes round in diameter.
