Drill bits for cutting metal, sharpening drills, grinding and polishing

When performing construction or repair work, it is often necessary to cut a metal workpiece. To do this, you should use special equipment in the form of a cutter, grinder or hand scissors for metal... However, it is not always at hand. To cope with this task, you can use a drill attachment for cutting metal, which will cut a product of small thickness.

Varieties of drill bits

Many craftsmen are used to using a drill for its intended purpose, namely for drilling holes. But not everyone knows that this tool can be turned into a multifunctional device, supplementing it with special attachments, fixtures and stands, which will make the drill versatile and indispensable in any work.

With the help of special drill bits, which can be bought at any specialized store at an affordable price, you can drill holes of all possible diameters, cut, grind, polish, twist, mix and milling. There is also a pump nozzle for a drill designed for pumping liquid. The attachment for plucking chickens is simply irreplaceable in the household. With the correct and competent use of additional attachments, the result will not be of the worst quality, as with the use of a special single-purpose device, but the cost of such a universal tool will be several times lower.

By design, all existing attachments are divided into:

• accessories for drilling holes and crowns;
• scissor attachments for metal cutting;
• stops;
• corner fixtures;
• grinding and polishing attachments;
• equipment for milling wood and metal;

• the equipment must be securely fixed in the tool holder;
• the drill must be held with two hands, which is especially important for powerful models;
• constantly adjust the pressure of the tool;
• work in personal protective equipment;
• after completion of work for several minutes, do not touch the drill to avoid burns.

What are metal cutting drill bits

Equipped with a special attachment for cutting metal, an ordinary drill turns into a punch or cotter pin. The device penetrates a metal product due to the implementation of numerous reciprocating movements along the inner cavity of the matrix. As a result, a straight cut line with a width of 3.1 mm is formed while maintaining a protective layer on the surface of the metal sheet.

Important! The maximum efficiency of the nozzle is achieved only when working in conjunction with an electric drill, the rotation frequency of the chuck of which is at least 2700 rpm.

The metal drill bit can handle cutting such metal products:

• aluminum, up to 2 mm thick;
• made of brass, copper, zinc, galvanized steel and sheet iron, up to 1.5 mm thick;
• made of stainless steel, up to 0.8 mm thick.

Using a drill bit for cutting metal has several advantages:

• the cut is of high quality;
• there is no need for the constant purchase of consumables, which saves financial resources;
• provides high productivity when cutting metal;
• versatility of the device;
• the equipment is convenient and easy to use and maintain;
• the nozzle can be used for electric and pneumatic drills;
• using the attachment, you can make cuts of any configuration.

Despite all the above listed advantages, in order to get a high quality cut, some skills and dexterity are required to work.

Popular attachment models

Today there are a large number of different models of drill bits, thanks to which you can not only cut metal in a straight line, but also make curly cuts. This is necessary when installing ventilation ducts, roof structures, gutters. The use of the attachment allows you to cut in any position without making preliminary adjustments.

Types of attachments:

• the punching nozzle "Steel Beaver" is used for cutting metal tiles, corrugated board and any flat profile sheets;
• universal nozzle "Cricket" is used for cutting profile metal, polycarbonate and plastic;
• special attachments for making curved and curved cuts are represented by the EDMA Nibbek, ACRO YT-160 A, Sparky NP 1,8 L models, which differ in the thickness of the processed sheet.

Drill scissor attachment "Steel beaver"

The classic drill bit for cutting metal tiles and any flat metal sheets in the form of a freely rotating shaft in a bearing with a fixed eccentric works on the principle of a crank mechanism with the difference that energy is supplied here for rotation.

A full-fledged cutting tool has a support part located on the bed and a movable part connected to an eccentric. It is the moving part that reciprocates during the rotation of the shaft. A mandatory structural element is the handle, which is fixed perpendicular to the axis of rotation of the spindle. As the load increases, a reactive torque arises, due to which the drill moves relative to the bit.

It should be remembered that the tool must be positioned strictly vertically relative to the workpiece when cutting. Failure to do so could result in damage to the product and injury to the operator.

The device resembles a scissors for metal. The drill bit is used for cutting flat products or profiled sheets with large bends. The cutting line is easy to control. During the operation of the tool, the protective layer of the coating is not burnt, which excludes the formation of sparks and the likelihood of burrs. You can perform continuous cutting of a product of any length. You can buy a drill attachment for cutting metal tiles and flat metal sheets for 1600 rubles.

The sheet is cut at a drill speed of 1500-3000 rpm. The cutting angle is 360 degrees, the minimum radius is 12 mm. With the "Steel beaver" nozzle, you can cut:

• copper or aluminum sheet 2 mm thick;
• steel - no more than 1.8 mm;
• from stainless steel - up to 1.2 mm,

Helpful advice! For cutting a profiled sheet with small-diameter bends, use the Sverchok-type shears.

Drill bit "Cricket"

The Sverchok nibbler got its name from the characteristic noise during operation of the device. The bit is similar to the previous model, but has a different design of the working element, consisting of two cutting heads. The principle of operation of the Cricket nozzle is similar to that of an office punch. Neat holes are squeezed out in metal during the oscillatory movements of the cylindrical striker with a high frequency. Thanks to translational movements along the marked line, it is possible to obtain an even cut.

The Sverchok scissor attachment is used for cutting thin metal and profiled sheets, and polymer thin-sheet products up to 2 mm thick. Work can be carried out horizontally and vertically. Thanks to the ability of the tool to rotate 360 ​​degrees. you can drill large round holes and make artistic cuts. You can buy a drill bit for cutting metal "Cricket" for an average of 1500-4000 rubles.

The tool can cut metal with stiffeners and various profile stampings in two ways. The first option involves repeating the profile surface, bending around the edges. Used for products with a medium bend radius. For cutting metal tiles, another cutting option is used, according to which the tool moves along the stiffeners without bending around the sheet profile.

Before you buy the "Cricket" drill attachment, you should consider the main drawback of the tool. Due to the fact that the nozzle punch has a diameter of several millimeters, when cutting the product, a cut of a certain width is formed, which leads to certain material consumption. The result is metal shavings with sharp edges in the shape of a crescent, which should be disposed of immediately for safety reasons.

Helpful advice! Do not wear soft shoes when working with the tool.

One of the most popular models is the "Cricket" scissor attachment for metal up to 1.6 mm Enkor 14210. The tool is capable of cutting a fairly thick metal sheet in a straight or curved direction.
