Metal cutting shears attachment for drill. Hand tools and attachments for cutting metal. How does a screwdriver attachment work?
NRM is an analogue of the actuator of cutting shears. It works on the principle of a cutting stamp. The source of movement for it is the electric motor of the drill. The rotational movement from the cartridge is transmitted to the connecting rod-crank mechanism of the nozzle. This mechanism converts it into reciprocating and drives the punch. The latter creates a cutting line of the desired shape and width.
Taking into account the coincidence of the operation schemes of the actuator of the scissors and the NRM, let us consider the principle of operation of the latter using the example of the kinematics of electric cutting shears.
Explanation of the picture:
1 — matrix holder;
2 - matrix;
3 - punch;
4 - slider;
5 — connecting rod;
6 — crank shaft;
7 - electric motor.
Rotation from electric motor 7 (via 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 transmitted to the slider 4. The punch 3 is fixed in the slider, and the matrix 2 is fixed in the matrix holder 1. The material to be cut is placed in the gap between the matrix and the punch. When the latter moves downwards, it is cut and moved in the desired direction (possibly in any direction). Successive cuts form a continuous cutting line. The cut piece is separated along it.
What metal can be cut
The following metals can be processed using NRM:
- aluminum. Thickness ≤ 2 mm;
- copper, brass, sheet iron, pure zinc and steel coated with zinc - thickness up to 1.5 mm;
- stainless steel, thickness up to 0.8 mm.
What determines the quality of the cut?
Enterprises, taking into account market demands, produce NRMs that operate on the same principle, but, naturally, various designs. They have different technical characteristics:
- Some NRMs are designed for strictly defined brands and sizes of materials, have a simple design, higher reliability and lower cost. Devices of this group provide higher quality products. But if necessary, cut various metals, you should purchase a whole line of such devices. Therefore, they are used for mass processing of metal of one standard size;
- others are universal nozzles"for all occasions." They are more complex, more expensive and the quality of processing on them is somewhat worse. To receive best quality products, 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 being crushed and they will turn out 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 armature has reached optimal speed.
Cricket attachment for cutting metal
The NRM “Cricket” device is very popular. Let's look at it using the example of the Anchor 14210 model, which can be used in conjunction with any drill.
NRM "Enkor 14210" is designed for cutting metal up to 1.6 mm thick. It is fixed in a cartridge, which activates the nozzle mechanism.
Works on the principle of cutting scissors. Allows for all types of cuts. The use of tool steel for its production makes it possible to ensure maximum strength. The design results in low noise and mechanical losses.
Attachment for a screwdriver for cutting metal “Steel Beaver”
The second very popular NRM device is the “Steel Beaver” screwdriver attachment.
It is designed for cutting flat and profiled sheets (for example: metal tiles, corrugated sheets, etc.). In the process of cutting metal, the NRM “Steel Beaver” does not burn protective layer metal coating(does not form sparks), which ensures the safety of the anti-corrosion coating of the metal.

Cutting metal with a screwdriver or drill: advantages and disadvantages
Compared with other equipment, NRM have a whole series advantages:
- high quality cutting with the ability to make cuts of any shape;
- high efficiency. This is explained by the fact that no consumables are needed;
- high performance;
- ability to process many types of metal;
- comfortable operating conditions;
- the ability to work in conjunction with an electric or pneumatic drill (a screwdriver is allowed);
- does not require expensive maintenance.
However, despite all the advantages of NRM, it has disadvantages. To ensure high quality cutting, certain skills and dexterity are required. In addition, it damages neighboring areas of the workpiece and often becomes the root cause of corrosion.
What not to expect
In general, do not think that NRM will always be a replacement for several tools. Unfortunately, its power is incomparably low compared to professional-grade electric scissors. This attachment is not designed to effectively cut thick metal sheets. It should be remembered that the maximum that it can cut is steel sheet 2.5 mm thick. In professional and, especially, industrial metal processing conditions, a more powerful specialized tool should be used, among which the grinder stands out. This tool is capable of efficiently processing metal workpieces of almost any thickness.

Almost every specialist involved in construction and construction is faced with the need to cut any metal products. repair work. For high-quality metal cutting, many professionals use the most different instruments, starting with a cutter, grinder and ending hand scissors. But what to do if at the right time there are no such tools at hand, and cutting metal is extremely necessary. This process can be carried out using conventional electric drill. Now at construction stores For these purposes, you can purchase specialized drill attachments for cutting metal.
What is a drill attachment for cutting metal?
According to their own design features the nozzle resembles a punch or cotter pin, which, due to the matrix, penetrates the metal a large number repeated movements. After this, strips of the required shape are formed in the processed product. During the cutting process, the impact on the metal occurs in a targeted manner, which helps to preserve the integrity of the products as much as possible. A similar attachment repeats the work.
Using the nozzle you can process metal, following parameters:
- aluminum with a product thickness of up to 2 mm on average;
- stainless steel up to 0.8 mm;
- brass, copper, galvanized steel, iron sheets, zinc with a thickness of up to 1.5 mm.
It should be remembered that the softer the material being processed, the greater its thickness can be.
Features of the nozzle
Before actual work, the attachment is securely fixed in the drill (chuck), which puts it into action. The principle of operation is almost completely identical to the process of operation of electromechanical scissors, which make straight and shaped cuts without much difficulty. To ensure high quality cutting, the number of revolutions should be selected correctly. For example, for metal of small thickness, from 2700 to 3000 thousand revolutions is good. You should start cutting only when the drill has reached the required level of speed.
Typical types of drill attachments
You can find several models of drill attachments for metal on the market:
- nozzle "cricket"(acts like nibblers) - used for cutting thin sheet metal. Consists of two special cutting heads. The “cricket” attachment is often indispensable when carrying out roofing works. For example, such as cutting metal tiles or corrugated sheets. The use of such a nozzle allows you to avoid deforming the material and obtain even and beautiful cuts. Unlike cutting with a grinder, the attachment is capable of producing sharper, burr-free edges. Using a “cricket” you can also drill neat round holes of large diameters, including artistic cuts. If necessary, work can be carried out on horizontal and vertical surfaces. As an additional criterion, the “cricket” attachment helps to process the edges with special abrasive materials during the cut. The price of such a tool is often in the range of 4000-7000 rubles;
- nozzle " steel beaver» — for the most part, this type of nozzle is used when cutting profile and flat sheets of metal. In terms of its operating principle, the cutting mechanism of the nozzle itself is very similar to processing material using cutting shears or a “guillotine”. In addition, when using the “steel beaver” attachment, the protective layers of the metal coating of the sheets are not burned during operation and thus no sparks are formed. The use of a nozzle eliminates the risk of possible chips or deformation of the cut edges. This attachment can be used to cut polycarbonate, aluminum or plastic. Distinctive characteristics nozzles are: drill rotation from 1500 to 3000 thousand revolutions, minimum cutting radius - 12 mm, the ability to change the cutting angle 360 degrees, processed material thickness - copper and aluminum 2 mm, stainless steel - no more than 1.2 mm, ordinary steel – up to 1.8 mm.
There are many options for this instrument, from different manufacturers However, the principle of operation is the same for all.
Main advantages of nozzles
As a rule, experts identify several main advantageous differences between drill attachments and grinders:
- versatility of the tool;
- simplicity in after-sales service and application;

- good performance;
- the ability to make holes of any shape;
- saving money due to the absence of the need to use additional consumables in the work;
- ease of use of the equipment, achieved thanks to the special handle;
- Possibility of operation from a pneumatic or electric drill.
We should also not forget that to ensure high quality cuts, certain skills are required. Of course, unlike household or professional tools complex configuration, you won’t have to adapt for a long time to working with the nozzle. Any beginner will be able to cut through up to 10 meters of metal in 1 hour. The attachment can be attached to any type of modern drill.
In general, you should not think that a drill attachment for cutting metal will be a complete replacement for several tools at the same time. Unfortunately, the power of this equipment is not always enough compared to professional-level electric scissors. In addition, the maintained thickness of 1.5 mm does not allow for any really serious work.
If you do not take into account the degree of productivity of the tool, then the attachment can be purchased to perform not too resource-intensive work. In such situations, the nozzle will significantly save a lot of time and money.
