By purpose all existing nozzles are divided into:

  • accessories for drilling holes and crowns;
  • nozzles, scissors for cutting metal;
  • stops;
  • corner fixtures;
  • grinding and polishing nozzles;
  • equipment for milling wood and metal;
  • sharpening devices;
  • perosemny nozzles.

When working with any nozzle on the drill must comply with safety regulations:

  • the tooling must be securely fastened 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 instrument;
  • work in personal protective equipment;
  • After completing the work for several minutes, do not touch the drill bit to avoid burns.

Equipped with a special nozzle for metal cutting, an ordinary drill turns into a punch or splitter. The device punches a metal product due to the implementation of numerous reciprocating movements in the internal cavity of the matrix. As a result, a smooth cutting line of 3.1 mm width is formed with preservation of the protective layer on the surface of the metal sheet.

Important! The maximum efficiency of the nozzle is achieved only when working complete with an electric drill, the rotational speed of which is at least 2700 rpm.

In spite of all the above listed advantages, in order to get a high-quality cut, certain skills and skills are required for work.

Today, there are a large number of different models of nozzles on the drill, thanks to which you can perform not only metal cutting in a straight line, but also make curly cuts. This is necessary when installing the ventilation ducts, roof structures, gutters. Using the nozzle allows you to cut in any spatial position without making preliminary settings.

Types of nozzles:

  • cutting nozzle “Steel Beaver” is used for cutting metal, corrugated board and any flat profile sheets;
  • the universal nozzle “Cricket” is used for cutting profile metal, polycarbonate and plastic;
  • Special nozzles for performing 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 sheet being processed.

The classic drill bit for cutting metal tile and any flat sheets of metal 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 fed for rotation.

A full tool for cutting has a support part located on the frame, and movable – connected to the eccentric. It is the moving part that reciprocates during the rotation of the shaft. Mandatory element of the design is the handle, which is fixed perpendicular to the axis of rotation of the spindle. During the increase of the load, a torque torque occurs, due to which the drill moves relatively to the nozzle.

It should be remembered that the tool must be positioned strictly vertically relative to the workpiece when cutting. Otherwise, damage to the product and injury to the operator are possible.

The device resembles a metal scissors. The drill bit is used for cutting flat products or profiled sheets with large bends. The cutting line is easily controlled. When the tool is working, the protective coating layer is not burned, which eliminates the formation of sparks and the likelihood of burrs. You can perform continuous cutting products of any length. Buy a nozzle on the drill for cutting metal and flat metal sheets can be for 1600 rubles.

Sheet cutting is performed at a drill speed of 1500-3000 rpm. The cutting angle is 360 degrees, the minimum radius is 12 mm. Using the Steel Beaver, you can cut:

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

Helpful advice! For cutting the profiled sheet with bends of small diameter, you should use slotted scissors like “Cricket”.

Vysechnye scissors “Cricket” got its name due to the characteristic noise during operation of the device. The nozzle is similar to the previous model, but it has a different design of the working element consisting of two cutting heads. The principle of operation of the nozzle “Cricket” is similar to an office punch. In the metal with oscillatory movements of the cylindrical striker, neat holes are squeezed out with high frequency. Thanks to the translational movements along the marked line, it is possible to get a smooth cut.

The nozzle-scissors “Cricket” are used for cutting metal thin and profile sheets, and polymer sheet products with a thickness of up to 2 mm. Work can be performed in the horizontal and vertical plane. Due to the ability of the tool to rotate 360 ​​degrees. large round holes can be drilled and artistic cuts can be made. Buy an attachment to the drill for cutting metal “Cricket” can be an average of 1500-4000 rubles.

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

Before you buy a nozzle on the drill “Cricket”, you should consider the main drawback of the tool. Due to the fact that the nozzle punch has a diameter of a few millimeters, when cutting a product, a slit of a certain width is formed, which leads to certain material consumption. The result is metal chips with sharp crescent-shaped edges, which should be disposed of for safety purposes.

Helpful advice! When working with the tool should not wear soft shoes.
