Cutting scissors for metal nozzle drill. We cut metal with a drill. You didn't even dream of it! The principle of operation of removable elements

25.10.2019

With a wide range of drill bits to choose from, this versatile tool can replace many other tools. So, for example, grinding discs eliminate the need to purchase a grinder, and a nozzle for tightening screws and self-tapping screws will replace a screwdriver.

With these tools, you can do the following:

grinding;
polishing;
cutting;
mixing;
twisting;
drilling holes of different diameters;
milling.

When used correctly, the result will be of the same quality as if the work was done with a special single-purpose tool. you can’t do without a drill with different nozzles at, a pigsty, cages for rabbits and other outbuildings in the country.

Types of nozzles

All nozzles for drills are divided by purpose:

stops;
for drilling holes, crowns;
cutting, nozzle-scissors "Steel beaver" and "Cricket";
for drilling at an angle;
polishing and grinding;
cutters for wood and metal;
removable;
sharpening.

Parallel stop is used to adjust the immersion depth of the drill, there are also special drilling stands for the bottom of a secure tool holder. Apart from standard function drilling, a drill can make blind holes, for example, to install hinges in wooden furniture. In this case, a Forstner drill is used. The base of the hole is flat, and its edges are absolutely smooth. Or they use feather drills instead.

Cutting attachments

Unlike a grinder, drill bits for cutting metals work more delicately and do not deform the coating of the material being processed. The tool is driven by the chuck of the tool on which it is installed.

For cutting metals, you should choose drill models with a speed of at least 2800 rpm.

Benefits of cutting attachments:

even cut;
comfortable work;
easy to use and maintain, no adjustment required.

The attachment for the Cricket drill is a nibbler with two cutting heads. They are used for cutting thin sheet metal: profile metal sheets, metal tiles, profiled or sheet plastic, as well as polycarbonate. "Cricket" is simply irreplaceable when erecting on a site.

"Cricket" is used for sheets of materials with the following parameters:

the thickness of sheet steel should not be more than 1.5 mm;
stainless steel up to 1.2 mm;
aluminum, copper and plastic no more than 2 mm.

The cut after processing this nozzle always remains smooth, without notches, and the coating is intact.

To make a high-quality and even internal cut, you must first drill a hole.

The nozzle matrix rotates, thanks to which it can work with both horizontal and vertical surfaces. The recommended number of revolutions of the tool to use this tool is 3000 rpm, the minimum is 1500 rpm.

Also, for cutting profiled sheet metal and tiles, the Steel Beaver scissor attachment is used.

The principle of operation is similar to the previous nozzle, the cut occurs due to the frequent reciprocating movements of the punch, which bends the material and breaks it against the matrix. This tool can make curved and straight cuts. The minimum cutting radius is 1.2 cm. You can work with it at any angle (360 °). Compared to the Cricket, the equipment is able to cut a steel sheet of greater thickness - 1.8 mm. The main advantage of the nozzle is a smooth cut, and due to the absence of sparks, the protective coating of the material does not deform during operation.

At the end of work, you should carefully handle the sheet material, since the cut edge after processing becomes sharp.

Attachments for grinding and polishing

With the help of nozzles on a drill for grinding and polishing, you can carry out the following types of work:

metal polishing, wood flooring, as well as glass surfaces;
grinding of metal, details from it and other materials;
removal of corrosion, scale, chipping and old coatings;
glass edge grinding.

Compared to special tools, these devices have a low price, and can cope with a large number of different tasks, making any surface perfectly flat and smooth. In addition, they can process hard-to-reach places where it is impossible to use other tools. But due to not large sizes they are difficult to fulfill large volume work.

When purchasing a nozzle for a drill for processing wood or other material, you should carefully study the instructions. Since for different types snap-ins require different power and the number of revolutions of the tool.

All polishing and grinding attachments are a rod on which grinding material is fixed, such as foam rubber, felt, brushes or sandpaper.

The following types are produced:

plate;
disk;
fan;
drum;
end;
cup.

Polishing devices are divided not only by the type of construction, but also by the degree of hardness: hard, soft, super soft, embossed.

Cup

A cup attachment for a drill for grinding wood or other coatings consists of a rod for fixing in a cartridge, and a cup-shaped body filled with hard or light bristles. Most often it is used to remove corrosion or old coatings. Models with a soft polishing part are also available: foam rubber, felt or other similar material. The body is made of durable and lightweight plastic or metal. Soft nozzles on a drill are most often used for car polishing.

Disc and platter

Disc devices, like cup ones, consist of a rod, a body and a grinding material. The main difference from the previous model is the direction of the bristles (steel wire, brass brush), it is directed from the center to the edges of the disc. You need to use them carefully, as you can quickly ruin the coating.

Plate attachments for polishing or grinding drills are made according to the same principle as for grinding devices. But instead of a thread, they are equipped with a movable or fixed rod for fixing in the cartridge. Sandpaper is attached to them with Velcro.

Experts recommend purchasing plate nozzles with a moving rod, rubber or with a soft and thick layer between Velcro and the base. Since then you can adjust the angle of the drill and smoothly follow the contours of the material.

When working with a rigid cymbal, it is more difficult to control, and even with a slight tilt, it will make a noticeable indentation in the surface. As a result, you can completely spoil the material. Therefore, they are recommended to be used only with a firmly fixed instrument on the stand.

Fan (petal), drum and end

Grinding fan nozzles for a drill are a small disk in the center, to the edges of which petals of sandpaper or other abrasive material are fixed. It is convenient to process hard-to-reach places, internal cavities or grind holes with such a device, as it is able to take any shape. They are fixed in the drill chuck in the same way as previous models, using a rod.

Drums are made in the form of a cylinder with a rod, covered on the outside with sandpaper. Unlike a poppet attachment on a drill, the processing surface is parallel to the chuck, and not perpendicular. They process wood, metal, glass. Most often used for sharpening the end of glass. They are soft and hard, depending on the purpose of the appointment.

The end ones are a rod, at the end of which the processing material is fixed in the form of a circle or cone. Nozzles work on the principle of a file. Using them, you can increase the diameter of the hole, as well as remove notches and make the edges smooth.

Other nozzles

An angled drill attachment allows you to make holes in places where it is impossible to work normally. The angle can be adjusted or be fixed - 90 °. Drill bits are used for drilling in wood, concrete, ceramic and tiles, metal and other materials of large holes. They are made of high quality steel so that the holes are smooth, without chips and cracks.

The nozzle for sharpening drills is a body with a leash and a grindstone inside. The holes for sharpening have different diameters. Their number can reach 15 pieces. Mixer attachments are used for mixing various mortars, paints and other mixtures. Selected depending on the consistency. For tightening self-tapping screws or screws, there is also a special nozzle, but it should be purchased for drills equipped with a speed reduction function.

For bird owners, a pen-removable attachment for a drill for plucking birds has been developed. It instantly and safely removes all feathers from the carcass. In this case, the skin and meat are not damaged. Before work, it is not necessary to pre-scald the carcass or process it after plucking with a blowtorch.

The nozzle on the drill for plucking birds is easy to use, you just need to fasten the tool with high quality and bring the bird to it. It is made from easily washed materials and takes up very little space.

For those who work with wood material, different types of cutter heads are available. They allow you to make grooves of various shapes, machine holes or remove defects. They are pointed and backed.

Before working with any nozzles, you should check the reliability of their fastening in the chuck and the material being processed. The drill must be held with both hands. Be sure to use protective equipment (gloves, goggles) while working.

Homemade nozzles for a drill - video

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 the polymer coating, constant purchase of cutting discs is required, 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 cut sheet material with the following thickness parameters:

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 metal rolled products, 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. Suitable not only for flat sheets of metal, but also for profiled ones.

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 operation of the nozzle, 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.

Video: Nozzle-scissors for cutting "Cricket"

To date, there is a great variety of various tools, the tasks of which include cutting and cutting thin-sheet material. One way or another, they cope with their tasks, but they have one feature - universal scissors metal does not exist. Some devices are easily cut with flat sheet steel, others are great for stationary work, and still others, being household tool, barely cope with the task of cutting a drywall profile. The only exception is one device - cutting scissors, one of the options for which is the attachment for the cricket drill, which will be discussed in this article ..

How nibblers work

It is quite simple to imagine the work of nibblers - in fact, it can be compared with a chisel that makes breakdowns in metal with great frequency. Another comparison is the modern electric jigsaw, in which the standard saw blade with teeth is replaced by a punch rod (chisel). This principle of robots, combining a punching tool and a jigsaw, opens up wide possibilities and allows the use of a tool of this type even for figured cutting of sheet iron. It is for this reason that modern builders use a "cricket" for cutting:

profiled flooring;
any smooth steel, when we are talking about large amounts of work.

These are not the only reasons why the cleaver drill attachment has become widespread in the field of construction and repair.

Benefits of this tool

Another significant advantage of the cricket is its careful attitude to the protective and decorative coating or metal tiles. Punching through the material, it not only does not injure it along the edges of the cut, but, on the contrary, rolls it, thus protecting the end of the cut from corrosion. As a result, the metal lasts much longer.

Additionally as an advantage cutting metal nozzles for a drill, the following points can be distinguished.

High productivity – a 1 m long cut can be completed in less than a minute. Yes, the grinder cuts faster, but unlike the nozzle, it burns the protective and decorative coating.
What is the ability to overcome almost any obstacle. The wave and various bends are not a problem at all - you can direct the movement of the cutter not only left and right, but also up and down.
According to the manufacturers, this tool is able to easily handle metal up to 2 mm thick, which is quite enough to work with roofing materials.
The cost of the instrument can be called purely symbolic. It is at least five times lower than the price of professional cutting shears with built-in electric drive.

As for the shortcomings, the most significant is only one - it is almost impossible to achieve a perfectly even cut. In principle, it is not needed, since the edges in most cases are covered either by another sheet of metal or by special elements. If you try hard and come up with some kind of guide, then this problem can be solved.

Safety precautions when working with a "cricket"

In addition to the risks of cutting yourself on the edges of sheet iron, there are a couple more points that you need to beware of when working with a perforated drill bit. These are shavings - small and, most importantly, sharp fragments of metal in the form of a crescent. They can cause very serious trouble.

First of all, the shavings easily pierce into the legs, and this may not even be felt on hardened feet. Then suppuration begins and all the ensuing consequences. It is best to work with the tool in closed shoes.
The second point is, or rather, its impeller, which serves to cool the electric motor. Penetrating into the air intake hole, small metal crescents quickly disable the power tool. There is only one way to protect the drill - to pack it in a mesh material (for example, nylon tights).

In addition, we should not forget that small chips scattered around the yard quickly corrode, and if it remains, for example, on paving slabs, then rust eats into it and spoils appearance coatings. Timely cleaning of the workplace solves almost all issues.

What to look for when buying a "cricket"

Almost all tools of this type have the same design and work on the same principle - they are not provided with any additional options, and no additional devices are provided for them. Everything is simple - including the choice, approaching which you need to pay attention to just a couple of points.

In principle, decide for yourself what is best for you - cheap and cheerful or expensive, but for a long time. From practice, I can only say one thing - my first nozzle from Sparky worked in intensive operation without repairs and Maintenance within five years. By and large, we are not talking about such big money - a professional nozzle can be purchased for about 30-50 dollars.

In conclusion of the topic, the attachment for the “cricket” drill, it remains to add only one thing - to remind you that it is possible to extend the life of any tool through proper care of it. Every self-respecting master should clean his "breadwinners" at the end of work and control their technical condition. Naturally, one should not forget about caring attitude to the tool - hammering nails with a nozzle and generally using it for other purposes is simply wrong.

There are a great many tools that can be useful in everyday life or for infrequent custom work. In order to buy, for example, the so-called "grinder", you will need a considerable amount, and in the meantime the tool will lie somewhere in the garage or workshop idle, being unclaimed.

Not every tool designed for a particular job, a person is able to buy: it will take a lot of money and extra storage space. And, as practice shows, there is simply no point in this. But there is still a way out of this situation.

Nozzles are for the following works:

Drilling at an angle;
grinding;
Polishing;
Sharpening nozzles;
Drilling;
For cutting metal.

As can be seen from what has been said, having only one drill and a few nozzles, you can thus replace a lot of expensive tools and not waste your money.

Basic Sheet Metal Cutting Methods

Sooner or later, every homeowner, not to mention specialists, cuts sheet metal in one scale or another. Ever since labor lessons at school, and for many after, in production, such tools for cutting metal are known:

But time passes, and technological progress does not stand still. Mankind has invented a simple and inexpensive cutting tool that works in tandem with an electric drill called "metal nibbling scissors". This equipment is simple, constructive and very convenient in operation.

When there is one in the tool arsenal of any man, as well as an electric drill, then there are no problems with cutting a metal sheet and cannot be.

And if there is none on the farm, then it can be purchased at the nearest household or construction market.

Good alternative to Bulgarian

This drill attachment has been helping out craftsmen for many years now. Such a tool is called nibbling scissors.

Easily punches a track about 3 mm thick in metal. This cutting method gives the desired cleanliness of the cut, and there is no particular need for further cleaning of the cut.

Thicknesses of materials that the scissors can cut:

Copper and brass - 1.5 mm;
Aluminum - 2 mm;
Stainless steel - 0.8 mm.

For metalworking

These nozzles are scissors simple and original design, where the rotational movement of the drill chuck is converted into reciprocating.

Nibblers "Cricket"

The technical capabilities of the "Cricket" nozzle allow cutting metal and plastics. Moreover, the material can be cut both sheet and profile. Two cutting heads of the cutting nozzle on the drill allow cutting materials certain thickness (specified maximum thickness):

For aluminum - 2 mm;
For steel - 1.5 mm;
For stainless steel - 1.2 mm;
For plastic - 2 mm.

Additional characteristics:

Electric drill power from 420 W;
Turnovers - from 3000 rpm;
Cutting radius (minimum) - 12 mm;
The cutting direction is unlimited, hence 360 degrees.

Application area:

Mounting;
Roofing works;
Production of gutters;
Disassembly of various structures;
Body work;
Curly (decorative) cutting.

When working with nibblers, the drill does not require any adjustments and special skills and knowledge.

The Cricket tool for cutting metal is very maneuverable, and its capabilities are cutting tool are very wide.

As for cutting with a grinder, there are a number of disadvantages here, compared with cutting shears for metal. The nozzle on the drill has a number of significant advantages:

The material does not overheat during cutting, which is especially valuable when cutting metal tiles.
The maneuverability of nibblers for a drill is much higher than that of a well-known grinder.
Higher cutting speed.
A cleaner saw cut that rarely requires further plumbing.
When working with nibblers for a drill, there are no jamming of the tool from distortions, which very often happens when working with a grinder, hence the almost complete absence of injuries.
The zinc and paint-and-lacquer coating of the material does not burn, which helps prevent premature corrosion and, which is very important, maintain the guarantee for the material.
When working with the Cricket tool for cutting metal, there are no sparks, unlike a grinder, which not only protects the material from burning, but also eliminates the possibility of injury to the eyes of the worker.

Nozzle-scissors "Cricket" has a number of analogues, for example:

"Beaver";
"Steel Beaver";
Scissor attachment NP 1.8 SPARKY;
EDMA NIBBLEX;
Malco turboShear TS1 - can be used with a drill and for installation on a screwdriver.

All of the listed nozzles have some differences on technical specifications and prices. The most expensive nozzle is Malco turboShear TS1. It has a slightly different design and is made in the USA, not China.

It should be noted that the normal operation of these devices can only be ensured when the passport speed of the drill is more than 2700 rpm.

Nozzle for screwdriver

If an electric drill is not available, then a screwdriver can also perform the same functions.

There is, however, a difference:

The revolutions of a screwdriver are lower than those of a drill. Low speed and, accordingly, the power of the power tool will not allow cutting metal with the same productivity, especially if it is closer to 2 mm in thickness.
Lack of inertia. After the user releases the button, the chuck immediately stops rotating. In terms of safety, this is even somewhat better, as well as in the case of a figured cut.
Small size and light weight compared to a drill. This allows you to do all sorts of "pirouettes" when cutting, more easily than with a drill.
Screwdrivers run on batteries, therefore, its operation is autonomous, and the power cord does not interfere with normal operation.
There is no adjustment of the rotation speed of the cartridge.

It is quite clear that a screwdriver can also be used instead of a drill with a Cricket type nozzle.

For cutting metal tiles and more

This nozzle is a real find for cutting material such as metal tiles.

Advantages:

Does not damage the material and coating;
Easily follows the contour of the material profile;
Able to make cuts of varying complexity.

"Cricket" is a real find for both the handicraftsman and the professional. It can make an internal cut and can work both horizontally and vertically.

The nozzle for cutting metal tiles allows you to cut metal tiles and corrugated board, with which this tool does an excellent job. After all, it is well known that it is difficult to work by making cuts in these materials with another tool, and the Cricket copes with this task perfectly: cleanly, quickly and without errors.

Advantages and disadvantages

Advantages:

Surface cleanliness is better than that of a grinder.
This device can make holes ("windows") of any complexity in the metal.
The tool is easy to use and maintain, takes up little storage space.
Low price.
You can cut both metal and plastic, as well as carbonate of a certain thickness, stated in the instructions for use of this equipment.
The possibility of using the device in places where there is no power supply is compensated by the presence of a cordless drill. In addition, it can be successfully used in damp rooms, where using an electric drill from the mains is life-threatening.
The device is multifunctional.
The low weight of the device is also an undeniable advantage.

Of the shortcomings, there is the only and main one: the device must be held with both hands, which is not always convenient and safe when working at height.

In conclusion, I would like to summarize what has been said. Any user, both beginner and experienced, who does not want to overpay for a fabulously expensive tool, can always buy an inexpensive analogue that will pay for itself very quickly by performing the same functions.

Very often it turns out that suddenly there was a need to use a cutting tool, and it was not included in the plans to buy something expensive, which is not known when it will be needed (if it is needed at all).

In this case, it is cutting shears for metal that will come in very handy.

That is why the cutting nozzle on the drill has found wide application in many branches of human activity: repair, assembly, dismantling and restoration.

Good luck with your purchase and enjoy working with the Cricket attachment for metal cutting!

Or a hacksaw is not available, then you can use an electric drill with a special nozzle for this purpose. Such devices allow you to separate a piece of sheet steel, and some models allow you to work with a metal profile.

These devices have not only a large number of advantages, but also limitations, the main of which is the thickness of the material with which you can work.

The use of such equipment can be not only in the absence of alternative way process the material, but also in the case when heating the metal sheet is undesirable.

Among the main advantages of using a nozzle on a drill, before using a grinder, the following can be distinguished:

Better cut surface quality.
The device allows you to make a hole in the metal of any shape.
Significant cost savings due to the lack of spending on consumables.
The tool is very easy to use.
Many nozzles allow you to work with both metals and plastic sheets of appropriate thickness.
When using a drill equipped with a rechargeable battery, it can be carried out in places where it is not possible to connect to a home electrical network voltage 220 V.
The ability to combine several functions in one device at once. If there is no need to cut thicker metal, then a drill can be used to drill holes and to cut the metal sheet.
Light weight fixture.

The main advantages of this product over other types of metal cutting are listed. Models of such nozzles can differ significantly in many respects, including cost.

Scissors

The scissors attachment for a metal cutting drill is a device that converts the rotation of the drill chuck into reciprocating movements, which, thanks to a special matrix, knock out a 3.1 mm thick strip in the metal.

With this method of separation, the cut is even and of high quality, which allows you to almost completely abandon the additional processing of the material in the future.

With a kind of scissors, you can cut metal, the thickness of which is not more than:

2 mm - when processing aluminum.
0.8 mm - if you need to cut stainless steel.
1.5 mm - for processing copper and brass.

This attachment for a drill for cutting metal will allow you to separate the material only if the electric motor of the tool develops at least 2700 rpm.

"Cricket"

The nozzle "Cricket" is a universal device with which you can perform the separation of not only metal, but also various plastics. The advantage of this tool is the ability to cut both sheet and profile material.

Thanks to the use of two cutting heads, the cut is perfectly even and does not require additional processing after cutting is completed.

With this type of device, it is possible to process material of the following thickness:

Aluminum - up to 2 mm.
Steel - up to 1.5 mm.
Plastic - up to 2 mm.
Stainless steel - up to 1.2 mm.

In order for the structure to last as long as possible, and the cut of metal or other material to be as even as possible, the manufacturer recommends using this device with a drill engine speed of 1500 to 3000 rpm.

"Beaver"

The nozzle "Beaver" works on the same principle as the above models. With it, you can perform both straight cuts and curved cuts with a minimum radius of 1.2 cm.

The beaver has slightly better characteristics for cutting sheet metal, for example:

Steel - up to 1.8 mm.
Stainless steel - up to 1.3 mm.
Aluminum - up to 2 mm.

Price of popular devices

Quality tools are not cheap. For cutting metal, fixtures must be made of a material that is not deformed when subjected to constant loads. Among the variety of both domestic and foreign manufacturers, the products of the following brands should be distinguished:

1. Nozzle - NP 1.8 SPARKY 181874 - the device is made in Bulgaria and is of high quality and reasonable price.

The device allows both linear and radial cuts, while the quality of the edge will be the highest regardless of the type of material to be separated. SPARKY 181874 can be used as a drill attachment for cutting metal tiles, which will significantly speed up the process of roofing.

Price for Russian market is about 2,000 rubles, but this cost is fully justified, since the attachment for the SPARKY drill is a high-quality product that will last a long time.

2. ENKOR 14209 - Cricket-type stray, Russian production.

The device allows you to perform high-quality cutting of sheet aluminum up to 2 mm thick. It is indispensable when working with roofing metal materials, since, unlike angle grinders, it does not heat the metal.

The thing can be purchased for 1900 rubles in any specialized store.

3. "Steel beaver" - made in Russia and allows you to work with various metals.

With the Steel Beaver, you can easily cut off a piece of aluminum, while the edges will be completely intact. The restriction on the maximum thickness of the metal, in this case, is 2 mm.

The device can also be used for cutting stainless steel. In this case, in order not to overload the tool, it is not recommended to use a sheet with a thickness of more than 1.2 mm. The cost of the stray is about 1600 rubles.

4. EDMA NIBBLEX - perfectly copes with the separation of sheet and profile material up to 1.2 mm thick. Aluminum sheet can be processed up to 1.5mm thick.

For the effective operation of the nozzle, the manufacturer recommended the optimal drill speed of 3,000 rpm.

The estimated cost of EDMA NIBBLEX in the Russian market is 5,000 rubles. The high quality of the device is confirmed by numerous tests by both professional craftsmen and ordinary people who purchase the device for home use.

5. Malco turboShear TS1 - can be used with a drill and for installation on a screwdriver.

The device is the most expensive of professional devices and will cost the Russian buyer 7,000 rubles. The nozzle is worth that kind of money, as it is made in the USA, where product quality control is much higher than in China.

If it is used for cutting for the first time, it is recommended that before starting the main work, make several cuts on unnecessary metal fragments in order to understand the basic principle of the device and avoid mistakes in the future.
When working with a metal cutting device, in order to obtain an even cut of the desired shape, it is recommended to hold the drill with both hands during operation.
Nozzles for Russian-made drills are practically not inferior in quality to foreign counterparts, while the price may differ significantly downwards.
It is not recommended to purchase devices from your hands, you can buy defective goods for a lot of money.
Tools should be stored in rooms where the possibility of metal oxidation due to high humidity will be excluded.
