Universal metal scissors – cricket attachment for drill. We cut metal with a drill. You never dreamed of this! Thicknesses of materials that scissors can cut
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 simple design, higher reliability and lower cost. Devices of this group provide more high 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 screwdriver attachment “ steel beaver».
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 the protective layer metal coating(does not form sparks), which ensures the safety of the anti-corrosion coating of the metal.
Characteristics of the NRM “Steel Beaver”:
- recommended drill rotor speed, rpm: 1500…3000;
- minimum cutting radius, mm: 12;
- permissible changes in direction and angle of cut, degrees: 360;
- maximum thickness of processed sheet, mm:
- steel - 1.8;
- stainless steel - 1.2;
- copper and aluminum – 2;
- weight, g: 400.

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 a 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.

On this video useful attachment for a screwdriver or for an electric drill. The author recently purchased this tool for cutting sheet metal, tin, and corrugated iron. The device is compact, weighs only 400 grams, and is convenient to use. You can buy it in this Chinese store.
Equipment. In addition to the device itself, a key is included. On one side there is a hex key, on the other there is a 12 key.
How does a screwdriver attachment work?
The shank is screwed to the chuck, the working part cuts the metal. The handle itself unscrews. And in the place where she was, there is another knife. If you loosen the nuts, the blades can be rotated to any angle. They rotate around their axis. They are secured with the same nuts. The nozzle is very simple. The knives work due to the eccentric. Excellent for cutting sheet metal.
The video shows how a metal sheet 1.5 millimeters thick is cut.
This attachment is for cutting thin sheet profiled metal up to 0.8 millimeters thick. The kit includes a replaceable matrix, a replaceable punch, and a handle holder. It has a low cost and is suitable for small volumes of work.
The device has two cutting surfaces. The handle must be installed before installation. When one plane becomes dull, unscrew the handle, turn the nozzle over, and install it on the other side. We insert it into the drill and fix it. You can start cutting metal.
As shown in the video, the cut is without deformation, the speed is decent.
There is a myth that an angle grinder cuts faster. Check shows that this is not the case. The grinder is slightly slower than the drill attachment.
The most important thing is that the cut is very even, smooth, without snags. Grinder cut with burnt coating, burnt zinc. During cutting there are a lot of sparks that fall on paint coating on metal. If sparks from the grinder fall on polymer coating, surface on next season may become rusty. Every self-respecting manufacturer categorically prohibits cutting with a grinder. If the cutting technology is violated, the warranty will be voided.
There are disadvantages when using the nozzle. You have to work with metal using both hands. This is difficult to do on the roof. But it will do an excellent job with your roof and your neighbor’s roof.
The jigsaw attachment is designed and manufactured to the highest standards, using the expertise of some of the UK's finest craftsmen and engineers. Cuts cleaner, faster and longer. Mounted on any drill: electric, pneumatic or battery-powered with a chuck up to 18 millimeters in size at a rotation speed of one thousand five hundred to three thousand revolutions per minute.
If you pre-drill a hole with a diameter of 12 millimeters, this will allow you to cut out a figure of almost any shape in the material. The jigsaw cuts materials at a speed of 1.5 meters per minute with a drill rotation speed of 2500 rpm.
cuts stainless steel up to grade 18, mild mild steel up to grade 16, copper, brass, aluminum, corrugated plastic, plexiglass and fiberglass up to grade 14.
The tool makes even cuts even on the most soft materials, which allows you to get any shapes with neat edges.
After cutting, the workpiece does not need to be leveled or cleaned with a file. You will be pleasantly surprised at the durability of these heads. It gives you maximum maneuverability.
If you've ever spent hours working with a hacksaw or the room became full unpleasant smell from the work of an angle grinder, you will see the difference.
Working with metal with such a tool is safe. You can work with even the smallest details. It allows you to work freely while holding the drill in your hands when performing roofing, plumbing, auto body, heating and ventilation work. The patented specially shaped cutter facilitates roofing and siding work without damaging the profile of the materials.
If you are remodeling a car according to special customer requirements, you fit speaker systems, perform plumbing, ventilation work, install kitchen sinks, make round or square holes, then you can no longer do without the help of a drill attachment.
You can use it to cut out windows in your RV or mobile home. It is easy to change the punch head and cutter. Depending on your goals, you can change the position of the head. You have four positions at your disposal. The tool rotates on the drill. Therefore, it is comfortable whether you operate with your right or left hand. You can't imagine how nice it is to work with him. The jigsaw cuts the metal itself.
You don't even have to make an effort. Simply guide the tool or part. It cuts not only cleaner, faster and longer, but also easier. You get a lot more and pay a lot less. Modern achievements of science and technology were used in the manufacture of this instrument. easy to do too.
Can't always find foliage finishing material required size and shapes. During repairs and installation of fencing made of profiled metal sheet, devices roofing covering you need to quickly cut this or that workpiece and adjust the standard element to the actual dimensions. For cutting, you can use an angle grinder, scissors, etc. cutting tool. If you don’t have it at hand or you are limited on funds, then there is an alternative – a cricket attachment for a drill.
Brief description
This is a removable mechanism that is installed on a standard chuck of an electric hand drill. It is designed for cutting flat and corrugated metal sheets:
- Composite aluminum sheet up to 2 millimeters thick
- Galvanized profiled sheet up to 0.8 mm thick
- Copper, brass up to 1.5 mm thick
By appearance The cricket drill attachment resembles a steel blank cylindrical, with “fingers” sticking out in both directions. A cylindrical blank is a body through which torque is transmitted from the drill to two cutting surfaces. “Fingers” are paired dies in direct contact with the metal workpiece. The tool comes with a plastic threaded handle-holder, which is screwed onto one of the paired cutting surfaces.
In addition, a spare die and punch, as well as a hex key, are supplied with the nozzle.
Operating principle
The cricket attachment to the drill does not saw metal like an angle grinder, but cuts it due to frequent translational movements of the matrix. The working unit converts torque from the drill rotor. The tool cannot operate at low speeds. To obtain a high-quality cut, it must maintain a rotation speed of 2700-3000 rpm. If this parameter is not met, then the metal around the cut bends, and the quality of the finished product deteriorates.
Scope of application
The attachment is widely used for cutting thin sheet metal. Its design is specially designed to perform both straight and curved cuts. Having certain work skills, you can perform figured sawing along a complex trajectory.
Unlike corner grinder or metal scissors, the “cricket” is capable of cutting from the center of the workpiece without creating through cuts.
The cutting attachment is especially in demand for roofing works and installation of fences. It's all about the material. Mostly profiled sheets are used, which are perfectly cut using this tool.
Positive properties
The cricket drill attachment is widely used thanks to a number of positive properties. It outperforms some power tools in terms of performance.
- Mobility. She has small size, much less than that of the Bulgarian. The attachment is easy to install and remove from the drill, making work easier
- High level of autonomy. The “cricket” has two full-fledged cutting matrices. If one fails, you can use the other. In addition, the tool comes with a third spare
- Maintainability. There is no complex mechanisms, there is practically nothing to break. The cutting part is supplied as a ready-made unit, which is easy to install on site
- Speed of work. Numerous tests show that the performance and sawing speed of the attachment are significantly superior to those of an angle grinder. Metal shears cannot be compared at all
- Cutting quality. According to this indicator, the “dragonfly” has no competitors. Due to the translational movements of the matrix, the edge of the metal in the cutting area remains smooth. There are no burrs on it. The metal does not heat up, the protective polymer coating of the profiled sheet does not burn. Zinc protection is not destroyed. While in the process of sawing with a grinder, the edges of the sheet are charred, burrs remain on them
- No collateral damage. Working with an angle grinder involves the formation of sparks that fly over a considerable distance. If a galvanized profiled sheet is processed, sparks burn out protective coating. During use, the metal will become covered with brown spots of rust. Sawing with the dragonfly attachment takes place in the complete absence of sparks. No rust problems
- Ergonomics. Handle holder makes working with the tool convenient and safe
Negative properties
There are not many of them, they do not have a critical impact on the choice of tool:
- Limitation associated with the type of grip. He only has two hands. Therefore, it is impossible to perform operations on inclined planes where to stay
- Metal thickness. The attachment is designed for cutting thin metal
Safe work rules
Practically do not differ from standard measures when working with sawing tools:
- Do not saw while holding the tool with one hand. This may cause it to bounce;
- Before starting work, check the rigidity of the handle holder. To do this, it is turned clockwise until it stops.
- It is allowed to work only in safety glasses and gloves;
- It is recommended to cut the sheet away from you, and not towards you;
- Do not work with a faulty tool. These include: a loose drill chuck, a ground sawing matrix, a loose handle holder
Manufacturers
Products from different brands are similar to each other. The main difference is in the thickness of the sheet that a specific model can cut. The price directly depends on this.
There are several companies worthy of attention on the Russian market:
- Anchor
- Corvette
- Sparky
Using scissor attachments on a drill greatly facilitates roofing work, installation of metal fencing, and other manipulations with sheet material. Convenient combination with hand drill allows you to reduce the cost of purchasing expensive specialized tools. Finished product It turns out neat and high quality.

Aliexpress is a huge online marketplace where thousands of sellers operate. Unfortunately, not all of them work honestly. Although the administration is actively fighting against scammers, there is still a risk of receiving a low-quality product or even being left without it. Therefore, it is worth learning how to choose stores for purchase. We talked about how this is done in the article.
While engaged in construction or repair work, almost everyone is faced with the need to cut some kind of metal workpiece. To perform this procedure, you can use a grinder, a milling cutter, hand scissors on metal.
But what to do if you need to cut a metal sheet, but there are no such tools at hand? You can solve the problem using an ordinary drill and a special attachment, which can be bought at any hardware store.
What are metal cutting attachments?
Such a device is, in fact, a cotter pin or punch, which is using a matrix to pierce metal. As a result of this, in the cut metal part a strip of the desired shape and width of 3.1 mm is formed.
Thanks to the targeted effect on the metal, the integrity protective layers products are preserved as much as possible.
Using the nozzle, you can process material that has the following thickness:
- aluminum – up to 2 mm;
- copper, brass, sheet iron, pure zinc and steel coated with zinc - up to 1.5 mm;
- stainless steel – up to 0.8 mm.
Cutting tool in action leads drill chuck, to which it is fixed. It is worth noting that the nozzle can cut metal only if the number of revolutions of the drill is at least 2700 rpm.
Advantages of attachments
Compared to a grinder, the drill attachment has a large number of advantages.
However, despite all the advantages of the tool, in order to ensure high quality cutting, working with it requires certain dexterity and skills.
Special attachment “Cricket” for a drill for cutting metal
Construction stores They offer several types of drill attachments for cutting metal.
Nozzle "Cricket". The “Cricket” device is a nibbler (cutting) scissors that can make an even cut. The tool is used for cutting not only smooth, but also profile metal sheets.
In addition to metal, they can cut plastic and polycarbonate. The Cricket is used for cutting thin-sheet products:
- The maximum thickness of sheet steel should be 1.5 mm.
- The maximum thickness of stainless steel is 1.2 mm.
- The maximum thickness of copper and aluminum is 2 mm.
- Plastic thickness – 2 mm.
Using the Cricket attachment you can cut on horizontal and vertical surfaces, as well as make internal cuts. To ensure a high-quality internal cut, the workpiece must first be drilled.
The tool is indispensable when performing roofing work that requires processing of metal tiles or corrugated sheets. After using Cricket, the materials used will not be deformed, and the cut will be smooth and beautiful.
If there is a need to make artistic cutting or drill a large hole in a sheet round hole, then the “Cricket” attachment can easily cope with this task.
Nozzle "Steel beaver"
The device is intended for cutting flat and profile sheets (corrugated sheets, metal tiles). It has a cutting mechanism, the operation of which is similar to the processing of materials with cutting shears.
In the process of metal processing using the “Steel Beaver” tool no sparks are formed and the protective layer of the metal coating is not burned.
Key Features:
- cutting is performed at a drill rotation speed of 1500–3 thousand rpm;
- the maximum thickness of aluminum and copper sheets should be 2 mm;
- stainless steel sheets must have a thickness of no more than 1.2 mm;
- maximum thickness steel sheet can be up to 1.8 mm;
- change of cutting direction and angle – 360 degrees;
