A drill is one of the most versatile tools on the farm. With its help, you can even carry out polishing and grinding work by choosing a special attachment. We will learn about the advantages and disadvantages of using attachments instead of the whole tool, about their types and areas of application. Let's figure out which drill attachment for grinding is suitable for which work, what types exist and what materials are used.

The drill attachment will help you make a square hole for a socket in 30 seconds
English engineers presented a device for quickly drilling square and rectangular holes in plasterboard walls for flush-mounted electrical installation products (sockets, switches, dimmers, etc.).
The Quadsaw device is simply inserted into the drill, after which you can start working. Thanks to four particularly strong blades and a built-in level, an even square (7.5 × 7.5 cm) hole of the required depth with absolutely smooth edges is obtained in the wall.
If necessary, the blades can be rearranged and a rectangular hole can be cut for a double electrical box.
For professional craftsmen, the cutting process takes from 6 to 10 seconds, for less experienced ones it will take no more than 30 seconds.

Tips for choosing
In a good half of cases, grinding attachments are sold under the brand name of electrical equipment manufacturers. It's good if both devices are of the same brand. Then there shouldn't be any compatibility problems.
It is better to look towards well-known brands. They care about quality due to high competition in the market. Although products from no-name manufacturers are much cheaper, the chance of running into a mediocre product in this case is much higher.
Popular manufacturers:
- "Bosch"
- "Makita";
- Dremel
- "Bison";
- "Matrix";
- Fit;
- "Enkor";
- Verto.
It makes more sense to overpay for quality than to constantly buy waste grinding attachments that wear off after several uses.
The wood splitter attachment will help you quickly “chop” wood chips and split small logs of wood.
A special chipping attachment for the drill will help you quickly complete the task, without the risk of injury. It is made in the image and likeness of a wedge-shaped cleaver, which in ancient times was used to split firewood with a hammer. The attachment is threaded for greater efficiency and works in tandem with an electric or cordless tool for increased performance.
This cone-shaped device, inserted into a drill or screwdriver, easily splits dry logs at low speeds and can also chop small logs.
A chipper with a length of 200 mm and a diameter of 40 mm weighs 900 g. The two-start thread takes up approximately half the entire length of the nozzle, fits perfectly into the log and quickly cuts it into chips.
The product is made of high-strength steel ST45 and has a hardened tip.
The nozzle is equipped with a special adapter that allows you to easily insert it into the chuck of a drill or screwdriver.
Price: 990 rub.

Homemade devices
It is not only the desire to save money that drives a person when creating a homemade nozzle - sometimes the necessary device simply cannot be purchased, and then one has to design and invent it. In this section we will show several options for attachments that can be made at home using improvised materials.
Based on Automotive Valve
To make such an attachment you will need one or more flat bottom car valves. It is better to make a larger nozzle from a truck exhaust valve.
The surface must be degreased and a head of the desired shape must be glued, which can be made of wood, dense foam, rubber and other suitable material, and then glued to the valve with epoxy or polyurethane glue.
Now you need to cut out circles from sandpaper. The nozzle turned out to be 5.5 cm wide - cut out the same circle for it.
Not reaching the center, cuts are made on the sides and adjusted so that each petal overlaps the other (as this device rotates).
Hot melt adhesive was used to glue the sandpaper.
After gluing the sandpaper, the edges of the petals were secured with staples.
The nozzle did an excellent job, but it quickly clogged because the sandpaper used was fine-grained.
Hence the conclusion - you need to make several attachments so that you can perform different types of work.
An attachment with a set of blades turns a drill or screwdriver into a reciprocating saw
The Drillpro attachment turns a drill or screwdriver into a reciprocating saw. This device is made of durable plastic and is a small box measuring 145 × 90 × 50 mm, inside of which there is a mechanism that converts rotational movements into reciprocating movements. Once inserted into the Drillpro, the blade is securely secured with a lock.
And the nozzle itself is inserted into the chuck of an electric or cordless tool.
The new product comes with 4 replacement blades with lengths of 100, 120, 135 and 150 mm for working on wood, metal and plastic. A special handle attached to the side of the attachment allows you to comfortably hold the tool with both hands and make precise cuts.
Approximate price: from 1200 rub.

Attachment for shaped cutting of metal and plastic products
The Australian company Canibble offers to use its original development for cutting sheet metal - nibblers, which are an attachment to a drill.
The new product is attached to any standard drill installed in a drill chuck and converts its rotational movements into reciprocating ones, allowing you to cut steel, copper, brass, PVC and aluminum, polycarbonate and other sheet materials with a thickness of no more than 2 mm.
Due to its maneuverability and minimal turning radius (8 mm), the nozzle makes it possible to make not only straight, but also curved, round and even ornate cuts in products of various shapes and configurations. It leaves no burrs or sharp edges at the work site, ensuring the cleanest possible cut.
The cutting speed with nibblers directly depends on the speed of the drill used, however, it is not recommended to use a tool with a productivity of more than 3000 rpm.
In addition to the attachment, the manufacturer offers special clamps that allow you to comfortably hold the drill in your hands while cutting materials, or permanently mount it on the work table.

Briefly about the main thing
A drill is a versatile tool that is easy to grind, polish and clean surfaces. To do this, just buy special attachments.
The advantages of grinding attachments include the ability to save on the purchase of unnecessary equipment and ease of use. Their disadvantage is lower speed and low productivity compared to professional tools.
Nozzles are divided into several types: cup, plate, drum and others. Each type is suitable for certain jobs, for example, hard plate attachments work well with preliminary processing of wood, softer ones - with final processing.
You can work with attachments in two ways: move a disk over the surface or attach a drill and bring the object to it. The first option is suitable for large surfaces, the second - for small parts.
Attachment with automatic screw feeding
Another attachment from Drillpro - for automatically feeding self-tapping screws - can turn a regular electric drill into something like a belt screwdriver.
The device is made of metal and literally consists of a couple of parts: a linen holder with screws and the feed mechanism itself. The attachment is attached to the drill using a mounting hole with a diameter of 44 mm and tightened with a clamp.
The nozzle mechanism is equipped with adjustment systems for screws of various sizes and screwing depths.
The screws are fed each time you press the wall of the tape holder.
You can purchase special tapes with self-tapping screws for use with this attachment, or simply insert new screws into the holes of the already used tape.
Price 1500 rub.

Drill requirements
Milling means processing an object with a cutter; it is located in the engine housing. The master controls the work processes, he regulates the speed of rotation and the depth of penetration into the workpiece. When working on a milling machine, the part being processed moves.
Electric drill with attachments
When using a drill, the device itself is moved, which must be suitable for milling. These operations require great precision, where the main force falls on the drive.
If the workshop plans to carry out small milling work that does not promise serious loads, a regular electrical appliance will do.
The operating principle of such a tool is based on the speed of the shaft, and it is ensured by the engine. From the functional part the load is transferred to the installed actuator - drill or cutter.
Equipment elements
These are equipment elements; they have to perform specific actions with the material:
- in-depth sampling;
- contour notch;
- cutting grooves or ledges.
The cutting element is installed taking into account:
- power unit power;
- management methods;
- drill brands;
- center of gravity.
Only at high speed can an object be processed cleanly. On a special machine they reach an average of 25,000 rpm. For the highest-speed drill, this figure is 4500 units. No model can achieve the same quality as a production router, but it is not always needed in a home workshop or even on a construction site. For a hand-held electric tool that transmits rotational movements to the equipment, the following conditions are required:
- shaft rotation at a minimum speed of 1500 rpm, it is desirable that the speed be regulated;
- mechanical power with a margin of safety, since milling occurs with large lateral loads;
- installation of a chuck that will ensure reliable grip of the shank.
If you mill with a drill in the wrong position, the resistance forces will be directed incorrectly:
- the load vector will change, which will bring the gearbox out of operation with additional pressure on the material;
- the engine will need frequent shutdowns to avoid overheating;
- the anchor is deformed;
- the cartridge will not withstand the influence of excessive forces.
To cut profile recesses with different recesses, recesses or grooves in workpieces, you need to select not only a drill, but also a cutting part in accordance with the configuration and width.
Nozzle for restoring broken threads
The mechanical connection using a bolt and nut provides a very secure fastening. However, it happens that an “unbreakable union” between them becomes impossible due to corrosion or any damage. Let's say it is almost impossible to screw a nut onto a bolt if the first few turns of thread on it are broken or rusted.
The developers of a special attachment for a Uniburr drill or screwdriver assure that it will significantly simplify the process of thread restoration, and will also help chamfer any products: stainless steel bolts, copper pipes, round and square rods made of brass and aluminum, fittings, wooden blanks and plastic parts. The new product is not suitable only for products made of chromium and molybdenum.
The attachment is made of strong steel and is compatible with any drill and screwdriver. The main thing is to work with the tool at low speeds (up to 400/min), since high rotation speeds can lead to premature failure.
Uniburr is designed for repairing knocked threads and is not suitable for fully threading the entire length of a bolt.
This device simplifies the repair process, reduces the time required to clean the thread, and also allows you to repair it by removing burrs where it was previously impossible to reach.
Price: 3500 rub.

Types of nozzles
Attachments for drills for grinding are made according to the same principle as replaceable blocks for polishing machines. They differ in the type of fastening: in special machines a thread is used, on a drill the fastening is made using a pin.
There are several types. The choice of a specific one depends on the material and the required operation.
Plate
Round nozzle with sandpaper. The latter varies in graininess and hardness. When working, the drill must go strictly at right angles to the surface. When tilted, defects and damage will appear on the tree. For convenience, some “plates” adjust the angle themselves.

Cup
The cup attachment for a sanding drill looks like a brush with long metal bristles. The shape resembles an inverted cup made of plastic or metal. There are also “bowls” with soft filling.
It performed well when working with wood. Metallic fibers release the fibers of the material, which well emphasizes the wood structure. The result is a natural look.
Device for converting a drill into a circular saw and grinder
A special adapter can turn the drill not only into a real circular saw, but also into a grinder.
The device consists of a clamp that securely fixes the drill, a mount for a gear wheel or grinding wheel, and a platform measuring 75 × 85 × 11 mm, which is screwed to the surface of the work table.
All adapter parts are made of metal and are particularly durable.
Having such a device in his arsenal, the master, in addition to the drill, receives two more useful tools: a circular saw and a grinder.
Price - about 800 rubles.

Drums
They are also called cylindrical, since they have the shape of a cylinder. The cylinder has not only different sizes, but also length, and sandpaper is glued (or threaded) along its edges. Drum polishing attachments for drills are analogues of fan attachments, and they are also used for cleaning and grinding the internal parts of pipes, holes, washers, etc. Unlike fan polishing attachments, drum polishing attachments achieve results much faster.
This is interesting!
The main feature of drum polishing attachments is that you can make them yourself. To do this, you need to take a wooden cylindrical block of the required size and glue sandpaper of the appropriate roughness to it on the outside. As a shank, you can use a pin placed on a cylindrical block.
An attachment for a drill that allows you to quickly make holes for planting plants.
Spring is a busy time for gardeners and gardeners. And many are already thinking about how to make their work easier and more productive. Perhaps the most important of the upcoming events is planting, which requires some effort.
A new device called MAXBIT will help to significantly facilitate and speed up this process. It is an attachment to a drill, with which you can quickly dig holes of the ideal size and shape. The device is simply inserted into any cordless drill instead of a drill, immersed in the ground, and after pressing the “start” button, it begins to rotate, creating a neat hole.
The new product has specially curved blades that push out the soil and throw it to the sides, leaving a round hole in the ground with a flat bottom, ready for planting.
MAXBIT is available in two sizes - with a diameter of 10 and 15 cm. The device comes with a kind of extension (63 cm), which is inserted between the drill and the attachment and allows you to work without squatting or bending.
The new product is made of durable steel and has a special coating that protects the metal from rust and damage and thus increases the service life of the product. The attachment is suitable for all drills, but the manufacturer recommends using a tool with a voltage of 18 to 24 V.
Price: Ø 10 cm – $40, Ø 15 cm – $50.

Design features
As mentioned above, almost every type of milling device has distinctive design features. This especially applies to end varieties. But at the same time, there are products with different tooth shapes.
An important element is the teeth.
the pointed teeth of the cutter have a serious drawback
The backed teeth behave completely differently. They are not afraid of frequent sharpening or intensive work with metal. Therefore, they are more reliable and durable. For drills, and for machines in general, this is an ideal option.
Is the milling cutter a single unit?
In addition to differences in shape, cutters are also divided into one-piece and prefabricated models. The first option is made from one piece. To avoid unnecessary waste of expensive material, many small cutters are made from one block. Therefore, this approach significantly reduces the cost of the product.
Prefabricated models are also available. As the name suggests, the cutter is manufactured individually and then all the components are connected to each other. Most often, the body is made of cheap types of steel, while the teeth are made of hard materials (most often alloys). Of course, the cost of the design increases, but thanks to this device, you can easily replace one component with another.
