10 attachments that turn a screwdriver or drill into a multifunctional device

Care and storage

regularly disassemble and clean the internal elements of the screwdriver from carbon deposits, dust and dirt;
if unstable operation occurs, carry out diagnostics. Check the wear of the brushes so that you do not have to change the engine armature;
do not leave the instrument in high humidity rooms or under the sun. The same goes for the battery;
keep the battery away from keys, coins, or other short metal objects. Accidental contact with the poles will short-circuit the battery. This could result in a fire;
at the end of the day, take a clean rag and wipe down the tool. The cloth can be slightly moistened with water without using detergents;
you need to store the screwdriver in a dry environment with a positive temperature. Use a case or other packaging to keep the tool free from dust.

Work with a screwdriver, observing the safety precautions and the rules described in the instructions. Choose the right rig. And then the tool will serve you for a long time.

Classification of cones by material

hard alloys;
carbon tool steels;
high-speed steel;
hard abrasives;
diamond-coated steel.

In addition, carbide cutters are coated with special materials based on nitrides and carbon to increase wear resistance.

Carbide

To improve the physical characteristics of the cutting edges of cones, special coatings are applied on their surface, which reduce the cutting force and increase the wear resistance of the tool. Currently, titanium nitride-based coatings are mainly used, each of which, among other things, paints the surface of the cutter in a certain color. The most common materials for such coatings are:

titanium nitride (yellow);
titanium aluminum nitride (blue);
titanium carbonitride (gray).

To improve chip removal when processing ductile metals (aluminum alloys, brass, etc.), cutters with a hard coating on a carbon base (LTE), which has a dark gray color, are used.

From carbon and high-speed steels

It should also be noted that high-speed steel has a high toughness, therefore, it is more resistant to vibration and changes in the hardness of the processed surface during processing. Unlike metals, milling of soft materials is done at low cutting speeds. In this case, the use of burrs made of tool and high-speed steels is preferable, including for economic reasons.

Abrasive

Abrasive grinding nozzles in their shape basically repeat the burrs, therefore in everyday life such a tool is called an abrasive cutter. They use ceramic, elastic and bakelite binders as a base, and, as a rule, aluminum oxide and silicon carbide serve as abrasive fillers. Solid nozzles are used for cleaning castings and welds, removing old coatings, oxides and scale, as well as straight and profile sampling of metal. Bakelite and elastic attachments are used for cleaning, rough grinding and precise removal of allowances on metal and other materials. Structurally, such a tool consists of a head in the form of a cylinder, sphere, cone, drop, etc., which is pressed onto a cylindrical metal shank.

Bracket for receiving a drilling machine

The multifunctional bracket helps you convert a standard hand drill (corded, battery powered) into a stationary drill press. The body is made of heavy-duty aluminum alloy.Massive, allows you to securely install the drill for subsequent drilling. The fasteners are designed to fit all modern power tools.

The sole is equipped with a vice, which allows you to fix the workpieces in the desired position, to avoid their displacement while drilling holes. The adjustable bracket allows you to set the desired height, taking into account the dimensions of the tool itself. For comfortable work, a rubber grip is provided that smoothly lowers the drill.

How to drill?

You work as follows.

First, apply the punch to the desired place and knock on it with a hammer until some depression appears.
Then take a screwdriver and drill with a drill. This will remove what the punch has crumbled, and you can also move a little more, since the drill is able to drill the mortar. But it cannot cope with large filler such as stone or rubble, so it can only drill before it hits them.
When the drill rests against a stone or rubble, then again we take a punch and pound on it with a hammer.
We repeat the steps until the desired result is obtained.

The job is not easy and requires a lot of effort. But nevertheless it leads to the desired result. That is, the work that the punch does on the go, in this case you will have to do it manually with a punch.

If during work you run into the reinforcement, then change the place of drilling. You can, of course, try to drill the reinforcement with a metal drill, but this will be an even more laborious process, so it is easier to change the place of drilling.

Drill Bit for Cutting Sheet Metal: Applications

The main purpose of such an accessory is the processing of metal blanks, mainly sheet iron. The variety of options and types available on the market makes it possible, with proper practice, to make not only straight cuts, but also curved cuts, which is necessary when:

installation of the roof;
installation of air ducts;
the manufacture of a drainage system.

When choosing a specific type, it is necessary to decide on the front of future work. Tools are commercially available for cutting round holesthat resemble a milling machine in the principle of operation

Also, using a nozzle, you can get devices for grinding metal, which is important if you need to process edges or seams, especially after welding or cutting.

All models of devices on the market are subdivided into specific types according to their area of application. They are:

for corner drilling;
performing grinding work;
for drilling;
allowing surface polishing;
used for sharpening;
used directly for cutting.

The difference between accessories for a power tool for cutting metal is not so much in the features of the functionality, but in the permissible thickness of the processed sheet, which must also be taken into account when choosing the optimal option.

How to use a screwdriver: useful tips for use

After purchasing a screwdriver, follow the simple guidelines for use. And then the tool will work for a long time and efficiently:

turn off the screwdriver before connecting and removing the battery;
do not bring the tool to overheating, take breaks;
adjust the torque adjustment clutch correctly;
after applying high speeds, set the minimum and turn the engine idle for a few minutes to cool it down;
check the cable of the mains screwdriver, and for the battery - the mains lead of the charger. If the tool or charger periodically loses the network, then the wire must be replaced;
do not use the screwdriver in rain or snow. In a humid environment, you can only work under a canopy.

Cutting metal with a screwdriver or drill: advantages and disadvantages

Compared to other equipment, HPMs have a number of advantages:

high quality cutting with the ability to cut any shape;
high efficiency. It is explained by the fact that no consumables are needed;
high performance;
the ability to process many grades of metal;
comfortable operating conditions;
the ability to work complete with an electric or pneumatic drill (a screwdriver is allowed);
does not require expensive maintenance.

However, despite all the advantages of HPM, it has disadvantages. To ensure a high quality cut, certain skills and dexterity are required. In addition, it damages adjacent parts of the workpiece and often becomes the root cause of corrosion.

What not to expect

In general, do 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 efficient 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, even more so, industrial metal processing, a more powerful specialized tool should be used, among which the grinder stands out. This tool is capable of efficiently cutting metal workpieces of almost any thickness.

For grinding and polishing

Some of the most popular attachments are tools for grinding and polishing the surfaces of metal and wood products. They differ markedly among themselves in execution and purpose.

Plate

They are almost a complete analogue of sanding pads used in electric sanders. The only difference is that instead of a connecting thread, they have a pin that is clamped into the chuck. Actually, if necessary, for a drill, you can use the working part of the grinder, having previously screwed a regular bolt into it.

The material from which this nozzle is made can be any. There are metal models, plastic ones, and rubber ones are often found. The latter precisely follow the contours of the workpiece, creating a perfectly flat surface. The cutting part of this nozzle is sandpaper. It is sold as finished discs with a special anti-slip coating.

Cup

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

Disc and fan

The disc nozzles have a cup-like arrangement. The only difference is that the brush is not limited by the size of the body, but, on the contrary, comes out of it, forming a kind of prickly "sun"

The nozzle is convenient for processing large surfaces, but requires caution during operation - one ill-considered movement is enough to ruin the product, and possibly get injured

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

Drum or cylindrical

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

Polishing attachments

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

"Cricket"

An efficient, reliable and popular nozzle. It resembles scissors in shape. This punching mechanism ensures a smooth cut. It cuts flat or profiled steel, aluminum, composite, copper, zinc equally effectively. In addition to cutting steel, you can use it for cutting thin polymer materials.

"Cricket" without flaws and defects cuts steel up to 1.5 mm, stainless steel up to 1.2 mm, copper and aluminum sheets up to 2 mm.

Its design makes it possible to cut in all planes. Make internal cuts without cutting through the workpiece. The comfortable handle provides a secure and secure grip.

"Sverchok" is ideal for processing metal tiles and profiled sheets. The working part does not destroy the protective layer, preventing corrosion.

Advantages and disadvantages

Cutting metal with a screwdriver has many advantages.

The result of working with a screwdriver is a high-quality and even cut.
Profitability. When purchasing a nozzle, there is no need to purchase additional consumables.
Great device performance.
The versatility of such attachments.
Due to the presence of a special handle, the workflow is light, convenient, and efficient.

Some models are applicable to any screwdriver and drill, electric or pneumatic.
The special attachments are quite easy to maintain.
This method makes it possible to carry out cuts in almost any configuration.

The disadvantages of this method of cutting metal include some inconvenience in work for novice craftsmen. First you need to adapt to the process, acquire some skill, even art. Experienced craftsmen will not need this - they will easily cope with the task. Another disadvantage of the product is the difficulty when working on the roof, since both hands are used when cutting metal.

Types of metal nozzles

With the support of specialized nozzles, which can be purchased in every shopping center at an affordable cost, you can drill holes of absolutely all possible diameters, cut, grind, polish, milling and other operations. All existing attachments, fitted on the heads of drills or screwdrivers, are divided according to their purpose.

There is also a drill bit for pumping liquids. With the correct and competent use of additional consoles, the result will not have the worst quality, as when using a special single-purpose device, but the cost of such a multi-purpose device will be several times lower.

Master Class. How to make a lathe from a drill

Surprisingly, a drill can also be used to create a simple lathe. All structural elements are made by hand (with the exception of screws and bearings). There is nothing superfluous - only the most necessary!

Step 1. The first step is to prepare everything that will be required for work.

What is required for a lathe

Step 2. Next, you should decide what the dimensions of the countertop will be. It is not necessary to take the dimensions given in the example - you can have your own.

Tabletop dimensions

Step 3. After that, the center of the drill is determined. It is placed on the countertop, then the distance from it (countertop) to the center of the chuck is measured. A square piece of wood is taken, a hole is made in it for the neck of the drill. The center of this hole will be the previously measured distance. This will fix the drill exactly.

Drill neck hole

Step 4. All unnecessary is cut off, after which the mount must be put aside for a while.

The excess is cut off

Step 5. We start assembling two corner pieces, which are a pair of rectangular pieces of wood glued together.

Assembling corner pieces

The smaller part (headstock) will hold the rotating workpiece from the opposite side, and the larger one is the bed, the tool itself will rest on it

It is important that the height of the headstock is about 1.5 times greater

Then, guides are created on both blanks - holes are drilled along the line, which are then connected at an angle.

Sloped holes

Step 6. 3 important elements are ready. Spray paint them if you like.

Three important details

Step 7. A hole is drilled in the headstock for the bearing (it should not be through). A bolt is inserted into the bearing itself, pulled together with a nut. Glue is applied to the seat, then the bearing is placed (it should be the nut outward).

Drill a small hole first Seating area Glue application Bolt inserted with nut outward

Step 8. The rails are attached to the tabletop.Holes are drilled (3 pieces) for long bolts, the drill mount is fixed with self-tapping screws. You also need to install a small wooden rectangle under the handle of the drill. All parts are screwed on.

Drill guides

Step 9. The drill itself is fixed with self-tapping screws - it must "sit" rigidly.

Drill inserted

Step 10. The structure is almost ready, all that remains is to make a clamp to hold the workpiece. For this purpose, a round is cut out, self-tapping screws are inserted into it, as well as a bolt with a nut.

A round is cut into it self-tapping screws are screwed into it.

Step 11. The finished part is mounted in the chuck.

Drill bit for cutting metal: how it works

HPM is an analogue of the cutting shears actuator. It works on the principle of a punching die. The electric motor of the drill serves as the source of movement for it. The rotary movement from the chuck is transmitted to the connecting rod-crank mechanism of the nozzle. This mechanism converts it to reciprocating and drives the punch. The latter creates a cutting line of the desired shape and width.

Taking into account the coincidence of the schemes of action of the actuator of the scissors and the HPM, let us consider the principle of operation of the latter using the example of the kinematics of the electric cutting shears.

Explanation of the figure:

1 - matrix holder;

2 - matrix;

3 - punch;

4 - slider;

5 - connecting rod;

6 - crank shaft;

7 - electric motor.

Rotation from the electric motor 7 (through a two-stage helical gearbox) is transmitted to the shaft of the crank mechanism 6. From it, the reciprocating motion through the connecting rod 5 is communicated to the slider 4. The punch 3 is fixed in the slider, and the matrix 2 is placed in the matrix 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 notched and moves in the desired direction (possibly in any). Consecutive cuts form a continuous cut line. The cut workpiece is separated along it.

What metal can be cut

With the help of HPM, it is allowed to process the following metals:

aluminum. Thickness ≤ 2mm;
copper, brass, sheet metal, pure zinc and zinc-coated steel - up to 1.5 mm thick;
stainless steel, up to 0.8 mm thick.

What determines the quality of the cut

Enterprises, taking into account the demands of the market, produce HPMs, operating according to the same principle, but, of course, of different design. They have different technical characteristics:

some HPMs are designed for strictly defined brands and standard sizes of materials, have a simple design, higher reliability and lower cost. The devices of this group ensure a higher quality of products. But if it is necessary to cut out various metals, you should purchase a whole line of such devices. Therefore, they are used for mass processing of metal of the same standard size;
others are universal attachments for all occasions. They are more complicated, more expensive, and the quality of processing on them is somewhat worse. To obtain the best product quality, 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 correct speed of the drill. This will prevent the edges of the metal from wrinkling, and they will turn out to be sharp.

For example, for metal of small thickness it is better to use a drill with a speed of 2700… 3000 rpm. You should start cutting directly only when the tool anchor has reached optimal speed.
