Nozzle scissors for a screwdriver for cutting metal. Nozzle for a drill for cutting metal - we mechanize a difficult operation. Rules for safe work

For repair and construction works metal needs to be cut periodically. It is not always possible or expedient to purchase special expensive equipment. In such cases, a nozzle on a drill for cutting metal can help out.

Special equipment for metal cutting

In production and construction, it is necessary to regularly cut metal sheets, cut holes in them, cutouts of various shapes.

Many types of tools and equipment can handle such tasks:

• . She is Bulgarian. Using special trimming wheels, it is possible to cut sheet metal, reinforcement. Often used for this very purpose. But there are drawbacks. Burrs remain on long cuts, not suitable for corrugated board, as it damages polymer coating, requires the constant purchase of cutting discs, which wear out quickly.
• Guillotine. Performs cutting of rolled metal with a fairly wide range of thicknesses. Has high performance. They are mainly used only in enterprises due to the high cost of equipment.
• A circular saw. It is possible to cut metal at different angles and with high precision. It is not possible to perform complex cuts, after working with it there is a lot of waste.
• Jigsaw. Allows you to cut the material at different angles. Suitable for cutting sheet metal.
• Metal shears. There are different types. For sheet steel - intended only for simple cutting of metal. Punching shears - in addition to straight and shaped cutting, it makes a variety of holes. Slotted scissors - do an excellent job with curly cutting, most accurately and accurately perform their task. The disadvantage of such tools is their rather high cost. Suitable for those who are professionally engaged in construction and repair. For one-time work and small volumes, the purchase of electric scissors is impractical.
• Nozzles for drills for cutting metal. There are two types - "cricket" and "steel beaver". According to the principle of operation, they are similar to cutting electric scissors, but several times cheaper in cost.

Nozzle on a drill "steel beaver"

There are undeniable advantages of using a drill for cutting rolled metal. Every master has this tool - both a professional builder and a summer resident.

Drill - versatile equipment due to the ability to change nozzles. They can be for drilling holes, grinding, milling, sharpening, etc.

The design of the nozzles on the drill

Structurally, the “cricket” nozzle is a punch with a matrix. The drill with its rotation informs the punch reciprocating motion. And two cutting heads accurately cut sheets of metal, punching them pointwise.

In the treated surface, cuts with a width of just over three millimeters are obtained. Thanks to such small cuts, the edges of the material remain as even as possible, without burrs. Since the nozzle does not heat up during operation, the protective and polymer coating of the cut parts is not damaged.

"Cricket" is great for working with sheet metal, polycarbonate or other similar roofing materials, including metal tiles. With this nozzle, it is possible not only to smooth the edge, but also to make holes (for example, for a chimney), to make artistic cuts. According to the principle of operation, these are cutting scissors.

The nozzle can be cut sheet material with the following thicknesses:

• polycarbonate (plastic) up to 2 mm;
• stainless steel up to 0.8 mm;
• aluminum up to 2 mm;
• zinc, iron, brass, galvanized steel up to 1.5 mm.

The nozzle for cutting metal is screwed to a drill or a screwdriver, clamped with the same nuts as the bits. The tool can be held at any angle, which makes it much easier to work with it. And also makes it possible to perform actions in any planes, which is indispensable for the installation of the roof.

Metal cutting attachment

The nuances of using "cricket"

The choice of "cricket" is determined by a lot of advantages:

• Neat cut. Unlike a grinder, a drill attachment will not leave burrs on metal surface and will not damage the polymer coating of the material with sparks.
• The lightness of the tool. There is no need to put in a lot of effort.
• Drill and screwdriver compatible. There is no need to purchase an extra tool.
• Price. Much cheaper than special equipment for cutting rolled metal, and also saves money on the purchase consumable type of cutting discs on the grinder.
• Easy to use. Easily installed on the cartridge, and also easily removed.
• Performance. With the help of the "cricket" you can quickly cut the material.
• Convenience. Thanks to its shape, it allows you to hold the tool at any angle.
• Ability to cut holes and cuts of any shape.
• Versatility. Not only suitable for flat sheets metal, but also for profiled.

And yet, certain nuances of working with a nozzle exist. The instrument must be held with both hands. That is, the material being cut must either be securely fixed, or the master must work with an assistant.

Like any tool, it takes skill. If you work with him for the first time, then it is better to practice first. For effective work nozzles, the rotation speed of the drill should be 1500–3000 rpm. But when buying a "cricket", you still need to clarify its characteristics and requirements - for some, the minimum cartridge rotation speed is 2700 rpm.

The "steel beaver" is similar in design and principle of operation to the "cricket". It also does a good job of cutting sheet metal. Curvilinear cuts are made with a minimum radius of up to 12 mm. The difference is that the metal can be thicker - stainless steel up to 1.2 mm.

And also you need to take into account that when working with these nozzles, a lot of metal chips are formed.

Safety

Regardless of the brand of drill and nozzle, their prices and characteristics, it is very important to observe safety precautions.

This will prevent injury and damage to the material.

• Wear protective goggles and gloves when operating the drill.
• Before starting work, it is important to check the fastening of the nozzle.
• Be sure to check whether the material to be cut is well fixed.
• The drill must be held with two hands for special holders.
• When working with a metal cutting attachment, constantly remove falling chips. For example, when installing a roof a large number of shavings can damage the surface of the metal tile.
• At the end of the work, for some time you should not touch the treated metal with your hands and remove the nozzles, as they can heat up due to friction.

So, when we cut metal sheets up to 2 mm thick, for example, when installing a metal tile or a corrugated fence, and the amount of work is small or one-time, it makes sense to turn your attention to drill nozzles.

A small nozzle with a name "Cricket" Designed for installation on power tools - screwdrivers, drills, perforators. It is able to cut sheet metal, which allows you to expand the functionality of the tool and perform more operations than usual.

Tool steel is used for manufacturing, which provides the tool with high level strength, and also makes it possible to work with most known materials. What's more, the carefully planned design ensures low noise levels.

At the main device where it is installed "Cricket", power must be at least 0.4 kW. This value allows you to effectively cut metal without bending the metal edge. It is worth noting that many household tools, such as a drill and a hammer drill, as well as a screwdriver, have such power.

The length of the fixture is 180 mm, which allows not only to carry out work in workshops, but also in confined spaces. The power sensing mechanism is based on a six-faced shaft, which has excellent grip and high strength compared to simple round shafts.

Thanks to the use of high-quality steel for the manufacture nozzle "Cricket" capable of cutting even thick metal sheets. For stainless steel this indicator is 1 mm, and for soft alloys - 1.6 mm. If we talk about aluminum, then the thickness can reach 2 mm. The nozzle makes it possible to do even round holes with a diameter of 11 mm or more. The features of the device also include a small width of the cut track - it has a size of only 1.6 mm. Thus, significant metal savings are provided, which cannot be achieved when using hand tools.

Nozzle for drill, screwdriver "Cricket" on Aliexpress: the best sellers and stores

Aliexpress is a huge online marketplace with thousands of sellers. Unfortunately, not all of them work honestly. Although the administration is actively fighting scammers, there is still a risk of receiving low-quality goods or even being left without them. Therefore, it is worth learning how to choose stores to buy. We talked about how this is done in the article.

HPM is an analogue of the actuating mechanism of punching shears. It works on the principle of a die cutter. 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 to reciprocating and sets the punch in motion. The latter creates a cutting line of the desired shape and width.

Taking into account the coincidence of the schemes of operation of the actuating mechanism of shears and HPM, we will consider the principle of operation of the latter using the example of the kinematics of electric punching shears.

Explanation for the figure:

1 - matrix holder;

2 - matrix;

3 - punch;

4 - slider;

5 - connecting rod;

6 - crank shaft;

7 - electric motor.

The rotation from the electric motor 7 (through a two-stage cylindrical gearbox) is transmitted to the shaft of the crank mechanism 6. From it, the reciprocating motion is already transmitted through the connecting rod 5 to the slider 4. The punch 3 is fixed in the slider, and the matrix 2 is in the die 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 incised and moves in the right direction (possibly in any direction). Successive notches form a continuous cut line. The cut workpiece is separated along it.

What metal can be cut

The following metals can be machined with HPM:

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

What determines the quality of the cut

Enterprises, taking into account market demands, produce NRMs that operate on the same principle, but, of course, various designs. They have different specifications:

• some NRMs are designed for strictly defined grades and sizes of materials, have simple design higher reliability and lower cost. Devices of this group provide higher quality products. But if you need to cut various metals, you should purchase a whole line of such devices. Therefore, they are used in the mass processing of metal of the same 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 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 right number of revolutions of the drill. This will allow you not to crush the edges of the metal, 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. Proceed directly to the cut should only be when the armature of the tool has gained optimal speed.

Nozzle "Cricket" for cutting metal

Very popular device HRM "Cricket". Consider it using the example of the Enkor 14210 model, which can be used in conjunction with any drill.

HRM "Enkor 14210" is designed for cutting metal up to 1.6 mm thick. It is fixed in the cartridge, which drives 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 causes a low level of noise and mechanical losses.

Nozzle for a screwdriver for cutting metal "Steel beaver"

The second very popular HPM device is the Steel Beaver screwdriver bit.

It is designed for cutting flat and profiled sheets (for example: metal tiles, corrugated board, etc.). In the process of cutting metal, HRM "Steel Beaver" does not burn the protective layer of the 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 rotation speed of the drill rotor, rpm: 1500…3000;
• minimum cutting radius, mm: 12;
• permissible changes in the direction and angle of the cut, degrees: 360;
• maximum thickness of the processed sheet, mm:
  • steel - 1.8;
  • stainless steel - 1.2;
  • copper and aluminum - 2;
• weight, g: 400.

SPARKY nozzle

Cutting metal with a screwdriver or drill: advantages and disadvantages

Compared to other equipment, HRM has a number of advantages:

• high quality cutting with the ability to cut any shape;
• high economy. It is explained by the fact that consumables are not needed;
• high performance;
• the ability to process many grades 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 adjacent sections of the workpiece and often becomes the root cause of corrosion.

What not to expect

In general, you should not think that HPM will always be a replacement for several tools. Unfortunately, its power is incomparably low compared to professional-level electric scissors. This device is not intended for efficient processing 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, moreover, industrial metalworking, a more powerful specialized tool should be used, among which the grinder stands out. This tool is capable of effectively processing metal workpieces of almost any thickness.

metal cut different ways: mechanical (drilling, milling and countersinking), gas, hydraulic, laser, plasma and other methods.

UShM - angle grinder "Bulgarian"

Mechanical cutting with a grinder, guillotine, circular saws or tape machines used in small farms and medium-sized enterprises. The main disadvantage of mechanical cutting is the rough effect on the material. As for the strengths, we can note the cost-effectiveness and high accuracy of processing.

Types and application of nozzles for a drill

Replacing the nozzle with a drill was faced by many who started repairs. Properly selected tool allows you to get rid of many problems, for example, from grinding work. Nozzle for drill external characteristics resembles a punch. Metal cutting is carried out due to the matrix and circular rotational movements.

Nozzle on the drill "Cricket"

Construction stores sell a variety of products, among which are:

• The nozzle "Cricket" is a cutting scissors. "Cricket" makes an even cut on a flat and profile metal. It is worth noting that "Cricket" can be used to process polycarbonate or plastic. "Cricket" is ideal for cutting sheet steel and profiles. In addition, the drill attachment can be used for cutting plastic and polycarbonate.

The thickness of sheet metal should not exceed 1.5 mm, stainless steel 1.2 mm, and aluminum 2 mm. "Cricket" is considered universal because it allows for horizontal, vertical, and internal cuts. The accessory is considered indispensable in roofing, especially when the roof is covered with a profile or metal tile.

• « steel beaver» it is used for cutting corrugated board, metal tiles and other flat profile sheets. "Steel beaver" copies the scheme of operation of cutting shears, however, during processing it does not form sparks and does not burn the protective coating. The nozzle is able to effectively process different sheets metal, but not more than 2 mm;
• Special attachments allow different types cutting. For example, curly and curvilinear are often installed on a drill when replacement gutters are required. drainage system or when repairing ventilation parts. The following types of nozzles are common in the construction markets: ASKO YT-160A, EDMA NIBBEL and Sparky NP 1.8 L. The listed models are easy to install the device and do not have significant differences in the scope of application. The difference between them is only in the thickness of the processed sheet. This option is best checked with the seller.

Nozzles for grinders and circular saws

At first it was said that the grinder is a universal tool, its capabilities cannot replace only a drill. It is used for cutting, grinding, polishing, sharpening and other types of work.

Discs are made of heavy-duty abrasive materials. The classification of canvases for grinders is based on their size, discs are known from 115 to 230 mm in diameter. The thicker the disk itself, the greater the force on the material and the higher the speed.

Despite its versatility and many positive reviews, the angle grinder also has several disadvantages, for example, it damages neighboring sections of the workpiece and becomes the root cause of corrosion.

Circular slab discs fall into two categories: discs for soft materials (wood, plastic, tiles, etc.) and metal discs. Devices for cutting metal products differ from their counterparts in a negative sharpening angle, that is, the teeth are directed in the opposite direction from the direction of rotation. It is worth noting that specialized nozzles are found on the construction market, for example, for laminate or plastic.

Circular saws of the modern type can process the material without heating it. That is, the processed part can be taken with bare hands, without fear of burns. It should be noted that cold cutting technology is used only in expensive models.

The difference between a drill and other tools

The drill is not suitable for efficient processing of thick metal sheets. The maximum that it can cut is a steel sheet 2.5 mm thick. Among hand tools, the grinder stands out, this tool is able to effectively process metal blanks of almost any thickness.

As for circular plates, they are distinguished by high productivity and processing quality, however, the machine is not suitable for processing thick sheets.
