Performance characteristics of the "Cricket" scissor attachment for metal up to 1.6 mm Enkor 14210

The device is intended for a complete set of screwdrivers and power drills, which have a power of at least 0.4 kW - this figure is average for this category of tools. This somewhat limits the scope of its application, since devices with a less powerful drive may be presented on the market. The internal mechanism is a standard hexagon - this shaft provides a more secure fit than a round one and has a significantly lower probability of slipping.

The maximum thickness of untreated sheet steel to be cut is 1.6 mm. When working with alloyed or high-carbon materials, the manufacturer recommends reducing this value to 1 mm. If the operator needs to work with aluminum, copper and other relatively soft metals, then the sheet can have a thickness of 2 mm. This makes the Cricket attachment a good alternative to traditional hand tools. The width of the cut path does not exceed 1.6 mm - this value allows you to provide significant material savings when performing complex work with small objects.

Also, the functionality of the device includes the ability to pre-drill holes with a diameter of at least 11 mm. The length of the nozzle is 180 mm, which makes it possible to work in confined spaces with maximum level facilities.

Features of the scissor attachment "Cricket" Enkor 14210

The undoubted advantage of the metal attachment is the absence of consumables, as opposed to cutting wheels for a grinder and a jigsaw. "Cricket" will not only help you quickly cut sheet metal, but also quickly make a large diameter hole in sheet metal. Also, using this nozzle, you can cut holes of arbitrary shape from pre-drilled holes with a diameter of 11 millimeters. In addition to all of the above, it is important to point out that the "Cricket" nozzle is very simple and convenient to use, does not require adjustment at all, which means that even a beginner will easily master it, and a professional will appreciate the convenience and speed of work.

For a more reliable attachment of the device, a plastic handle and a punch are used - they are included in the delivery set. This allows you to significantly improve the accuracy of execution permissible species works. The weight of 0.4 kg does not significantly increase the load on the operator's hands compared to the own weight of the appliance. Drill attachment for cutting sheet metal up to 1.6 mm thick. Works in conjunction with any drill.

At correct selection The number of revolutions of the drive shows excellent cutting results: it does not crease the edges of the metal, and at the same time they do not turn out to be sharp.

Need to cut sheet metal up to 1.6 mm thick? The "Cricket" drill attachment will solve the problem at no additional cost! What else can your drill do? You will find out in just a few minutes!

The most common tips and their descriptions

There are several hundred different attachments and they all differ in some way from one another. It is simply impossible to cover the entire range of products, so let's start with the most popular models that can replace your expensive tools. With their help, you will be able to perform basic construction and Finishing work, handle a variety of surfaces and materials. We do not take into account the drill and the "shovel", only additional accessories. Let's take a closer look.

Crowns. Unique attachments for making holes in wood. An irreplaceable thing in the manufacture of furniture. They have different diameters and heights. As a result of the work, you get perfectly smooth holes in any wood. The cost of such crowns is from 40 to 700 rubles per piece (depending on the manufacturer, steel grade, height and other parameters).
Screwdriver bit. There is nothing easier than making from a regular screwdriver. It is enough to buy inexpensive cruciform and straight tips and you have 2 types of screwdrivers at once. More precisely - 3 types, since there is also a percussion (punching function on a drill).
Metal brush circle. Used for metal work (mainly), it is a metal bristle that is located around the shaft, and he, in turn, is attached to the chuck. This shape is made to maximize the balance of the nozzle. When you turn on the device, the brush has a very high speed and removes all rust and irregularities in seconds!
Corolla. For mixing building mixtures, a specific nozzle in the form of a long screw and a large holder is used, which is inserted into the tool holder. With the help of such a thing, you can mix an excellent tile adhesive in a few minutes, mortar for laying bricks and whatever you want. Yes, at least mix the paint with a solvent! The quality of the mixture is much better than in the case of manual preparation of the mixture.

These attachments are known to almost every builder and have gained immense popularity not only in the construction industry, but also when performing many household tasks.

Rarely used attachments

Jigsaw. Incredible, but with conventional instrument a high quality jigsaw can be created with a rotating chuck. This is a nozzle adapter that converts the rpm of the chuck into usable energy, starting the complex swing mechanism of the saw. As a result, you will be able to process thick boards, and make the most complex patterns.
Flexible drill shaft or flexible drill. In fact, this is a standard nozzle, only it does not break when bent, but deforms without loss of strength characteristics. It becomes possible to get to the most inaccessible places, for example, in the head of a car, when installing industrial transformers, and the like.
Angle drill bit. There are several versions of this thing, but the most popular is the Bulgarian. You get high quality metal cutting, polishing and grinding tools.
"Cricket". Another rare attachment that allows you to make scissors for metal. Works with material up to 1.6mm thick, which is amazing. You can cut any pattern you need - it is very easy and convenient to control the cutting direction.

These attachments are not always relevant, sometimes it is easier to buy the appropriate device and not bother with them. If you need to perform one-time work, it makes sense to purchase an inexpensive adapter or device for solving a particular problem.

Grinding and polishing

In a separate group, it is necessary to make a huge number of nozzles intended for polishing, cleaning, surface grinding. With their help, you can not only remove paint or irregularities from metal or wood, but even remove a few millimeters of material, increase its strength and much more! Let's take a look at some of them.

Grinding attachment for a drill. Designed to remove rust on metal, eliminate visible product defects, sharpen steel cut and many other functions. Grinding drill bits are rods that hold abrasive bits. When the chuck rotates, it accelerates to the same speed and is used as a grinding wheel. The abrasive can have different grain sizes.
Drill attachment for grinding wood. A similar object, as for metal processing, only instead of an abrasive, a polyurethane, rubber, mineral (etc.) circle is installed, with which you can make the surface extremely smooth and without chips, needles.
Drill attachment for polishing. This is a specific tool, the base of which is made of rubber and foam rubber, an emery wheel can be attached to them. This design ensures maximum processing quality. Nothing worse than a polishing machine. The only drawback is that the drill turns out to be much heavier, so it will be a little uncomfortable to hold it.
Grinding "sun". Another unusual nozzle. It is a circle from which strips of sandpaper emerge like rays. When the chuck rotates, the paper petals accelerate to high speed and grind any metal in a few seconds! The attachment is short-lived, enough for a couple of hours of work, but very effective!

We've covered the most useful attachments. Now the choice is yours: use these devices or buy expensive devices.

The need for cutting metal products arises in many situations related to construction and renovation works... To perform this technological operation, special equipment is used. different types, but if it is not at hand, a drill attachment for cutting metal can help. Using such attachments and a hand-held electric drill, you can efficiently cut thin products made of various metals.

Types of equipment for metal cutting

You can cut a metal sheet or a more massive metal product using various equipment.

Angle grinder

This device is also known as the "grinder". It can be used to cut rebar, plate and other types of metal. This is the most popular equipment used for this purpose.

Metal circular saw

This saw allows you to make cuts at different angles and perform them with great accuracy. Meanwhile, when using this equipment, the resulting cuts have a limited depth and are formed a large number of waste.

Guillotine

This is a high-performance equipment for metal cutting, with the help of which workpieces of simple configuration are processed.

Bandsaw and jigsaw

This equipment allows you to make cuts at different angles. Both the jigsaw and the band saw because of their design features impose significant restrictions on the size of the products that need to be cut.

Hydraulic equipment

This type of equipment is innovative. It allows you to cut metal with high precision, while the thickness of the workpiece can be up to 20-30 cm. The most significant disadvantage of this cutting method, in which the product is not subject to thermal effects, is its high cost.

As mentioned above, drill bits, which are presented in a wide variety on the modern market, can also be used for cutting metal products.

Features of the use of drill bits

The attachments, with the help of which an ordinary electric drill turns into a device for cutting metal, are, in fact, a punch (cotter pin). Making numerous reciprocating movements in the inner cavity of the die, such a punch penetrates the metal sheet, forming a cut line on it, the width of which is 3.1 mm. When using nozzles, a point effect is exerted on the processing area, due to which the protective layers on the surface of the metal product fully retain all their functions.

Using the drill bit, you can cut metal sheets of the following thicknesses:

made of aluminum - up to two millimeters;
made of copper, brass, sheet iron, zinc and galvanized steel - up to one and a half millimeters;
made of stainless steel - up to eight tenths of a millimeter.

The reciprocating movement of the punch, which is the main working body of the nozzle, is communicated by rotating the chuck of an electric drill. It should be borne in mind that such a nozzle can effectively cut a metal sheet only if it is used in conjunction with an electric drill, the chuck of which rotates at a frequency of at least 2700 rpm.

Benefits of using drill bits

Drill bits, when compared with such a popular metal cutting tool as a grinder, have a number of advantages.

The cut performed is different high quality.
When using a drill attachment for cutting metal, there is no need to purchase additional consumables, which significantly saves money.
The use of such a nozzle ensures high productivity of the cutting process.
Drill bits are highly versatile.
Due to the fact that this tool is equipped with a special handle, it is very convenient to perform the cutting process with it.
These attachments are suitable for both electric and pneumatic drills.
The convenience of these attachments is undeniable both in use and in maintenance.
With these tools, you can make cuts in almost any configuration.

Despite the simplicity of the design of such nozzles, their use requires certain skills and dexterity from the user.

Popular models and their areas of application

Modern models Drill attachments allow cutting sheet metal not only in a straight line. With the help of such a convenient and easy-to-use device, you can also make curly cuts, which is often required when installing roof structures, ventilation ducts, as well as gutters and other elements. drainage system.

Using such drill bits, cuts can be made in almost any spatial position. An equally important advantage of these attachments is that they do not require preliminary adjustment.

Among the most popular models of drill bits for metal cutting on the domestic market are the following:

"Cricket" (from the "Enkor" company);
Sparky NP 1.8L;
EDMA NIBBLEX;
ACKO YT-160A.

The differences in the models of drill bits are not in the principle of their operation, but in the maximum thickness of the cut metal and a number of others technical characteristics... Modern models of drill bits allow you to get straight and neat cuts with sharp, smooth and unnoticed edges. In this case, the protective coating applied to the surface of the metal sheet is not damaged and fully retains all its functions.

"Cricket"

One of the popular drill attachments, which are compact nibbling (nibbling) shears, is a device called the "Cricket". This nozzle, which allows you to get a smooth and accurate cut, can be used to cut both flat and profiled metal sheets.

Scissor attachment "Cricket" is designed to operate from a pneumatic or electric drill (screwdriver) with a power of at least 420 W

With the help of the "Cricket" scissor attachment, you can cut not only a metal sheet, but also thin sheet products made of polycarbonate and other polymeric materials. In this case, the thickness of the products, for which these compact nibbling shears can be used, can be up to:

1.5 mm - for steel sheet material;
1.2 mm - for stainless steel;
2 mm - for copper and aluminum, as well as polymeric materials.

With the "Cricket" drill attachment, you can cut sheet material horizontally and vertical planes, and also perform internal cuts on the surface of the sheet.

It should be borne in mind that in the place of the sheet from which the internal cut will be made, it is necessary to pre-drill a hole.

"Sverchok" is a good drill attachment for cutting metal tiles and corrugated board. When using this device for cutting metal, the surface of these materials does not deform, and the cut itself is smooth and accurate. The "Cricket" nozzle can easily cope with such complex tasks as artistic cutting and creating a hole of large diameter in sheet material.

"Steel beaver"

Another popular drill bit that can be used to cut metal is the Steel Beaver. The principle by which such drill bits work is similar to how nibblers work. When using this device, sparks are not generated in the cutting area and no thermal effect is exerted on the metal sheet, respectively, the protective coating applied to it is not burned.

If there is a need to cut metal, and a grinder or a hacksaw is not available, then an electric drill with a special attachment can be used for this purpose. Such devices allow you to separate a piece of sheet steel, and some models also 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.

Benefits of drill bits

The use of such a tooling can be not only in the absence of an alternative method for processing the material, but also in the case when heating the metal sheet is undesirable.

Among the main advantages of using a drill bit before using a grinder are the following:

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

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

Scissors

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

With this method of separation, the cut is smooth and of high quality, which makes it possible to almost completely abandon additional processing of the material in the future.

With a kind of scissors, you can cut out metal, the thickness of which is no more than:

2 mm - when machining aluminum.
0.8 mm - if it is necessary to cut off stainless steel.
1.5 mm - for processing copper and brass.

This drill attachment for metal cutting will allow the material to be separated only if the tool's electric motor develops at least 2700 rpm.

"Cricket"

The "Cricket" nozzle is a versatile device that can be used to separate not only metal, but also various plastics. The advantage of this pribluda is the ability to cut both sheet and profile material.

Thanks to the use of two cutting heads, the cut is perfectly flat without requiring additional processing after the cut 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 smooth as possible, the manufacturer recommends using this device at a drill engine speed of 1500 to 3000 rpm.

"Beaver"

The Beaver attachment works on the same principle as the above models. It can be used to make both straight and curved cuts with a minimum radius of 1.2 cm.

The beaver has little the best 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.

Popular devices price

Quality tools cannot be cheap. For cutting metal, fixtures must be made of a material that, under constant stress, does not deform. Among the variety of both domestic and foreign manufacturers, the products of the following brands should be highlighted:

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

Drill bits for cutting metal: description and varieties, advantages, main characteristics

Engaged in construction or repair work, almost everyone is faced with the need to cut any workpiece made of metal. To perform this procedure, you can use a grinder, a cutter, hand scissors for metal.

But what if you need to cut a metal sheet, but there are no such tools at hand? You can solve the problem with an ordinary drill and a special nozzle, which can be bought at any hardware store.

What are metal cutting attachments

Such a device, in fact, is a cotter pin or punch, which punches metal with a multitude of repeated movements using a matrix. As a result, in the cut metal part a strip of the desired shape and width of 3.1 mm is formed.

Due to the point effect on the metal, the integrity of the protective layers of the product is preserved as much as possible.

With the help of a nozzle, you can process material that has a thickness:

aluminum - up to 2 mm;
copper, brass, sheet metal, pure zinc and steel coated with zinc - up to 1.5 mm;
stainless steel - up to 0.8 mm.

The cutting tool is driven by the drill chuck, on which it is fixed. It is worth noting that the nozzle will be able to cut metal only if the number of revolutions of the drill is at least 2700 rpm.

Advantages of attachments

Compared to the 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, certain dexterity and skills are required to work with it.

Special nozzle "Cricket" for a drill for cutting metal

Hardware stores offer several types of drill attachments for cutting metal.

Cricket nozzle. The Cricket device is a nibbler that is capable of making a straight cut. The tool is used to cut not only smooth, but also profiled metal sheets.

In addition to metal, they can cut plastic and polycarbonate. Cricket is used for cutting thin sheet products:

The maximum sheet thickness should be 1.5 mm.
The maximum thickness of the stainless steel is 1.2 mm.
The maximum thickness of copper and aluminum is 2 mm.
Plastic thickness - 2 mm.

Using the Cricket nozzle, you can cut on horizontal and vertical surfaces, as well as make internal cuts. In order for the internal cut to turn out to be of high quality, the workpiece must first be drilled.

The tool is indispensable when performing roofing work, during which processing of metal tiles or corrugated board is required. After using Cricket, the materials used will not be deformed, and the cut will turn out to be smooth and beautiful.

If there is a need to make artistic cutting or drill a large round hole in the sheet, then the Cricket nozzle can easily cope with this task.

Steel beaver attachment

The device is designed for cutting flat and profiled sheets (corrugated board, metal tiles). It has a cutting mechanism that works in a manner similar to cutting materials with a nibbler.

In the process of metal processing using the Steel Beaver tool, sparks are not generated and the protective layer of the metal coating is not burnt.

Main characteristics:

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 be no more than 1.2 mm thick;
the maximum thickness of the steel sheet can be up to 1.8 mm;
changing the direction and angle of the cut - 360 degrees;
the minimum cutting radius is 12 mm.

Drill bit models and their application

With special attachments on the drill, you can make both straight and curved cuts. Make curly cuts for the installation of gutters of the gutter system or ventilation parts of the roof, cut in the vertical and horizontal direction.

After using the tool, the cut is neat. The nozzle does not require adjustment and is easy to maintain.

On the construction market, drill bits are presented in several models:

ACKO YT-160A.
EDMA NIBBLEX.
Sparky NP 1.8 L.
"Cricket" from the producers of Enkor.

By and large, all models of drill bits work according to the same parameters. An exception may be the thickness of the metal sheet, which a particular tool can cut.

After using the tools, the edge is sharp, even and not wrinkled. It is only necessary to make sure that the speed of the used drill corresponds to the characteristics of the nozzle.

Those who are engaged in construction or repair sometimes need to cut metal. And, if it is not possible to purchase an expensive tool, then the cutting process can be entrusted to a drill with a nozzle.

For DIYers, this tool will become optimal solution and a great helper. It should be borne in mind that the cutting process can be entrusted to specialists who have experience and certain skills.

Drill bit for cutting metal

Sheet metal tiles are based on metal, which is covered with several layers of protection for a durable service.

Metal tile layer

The finished metal sheet profile is bent by cold pressure, alternately, first along, then across. At the same time, there is no heating process, which can spoil the properties of the coatings. At the same time, the quality of the material remains high, as it was originally conceived, durability up to 100 years, resistant to corrosion and UV radiation and similar qualities. But in the process of laying this tile, it sometimes needs to be cut for a neat and high-quality installation, while not damaging the outer layers.

The manufacturer gives a guarantee for its product, while indicating which tools should be used in order not to lose this guarantee.

When cutting the sheet, damage to the protective varnish layer should be avoided as the appearance of cracks and thermal effects in the form of sparks, deformation of the material.

Therefore, the following tools are considered the most applicable: Ordinary hacksaw for metal, hand scissors for metal, Circular Saw, jigsaw with metal cutting attachment, die-cutting shears. These tools can be used to cut metal tiles without damaging the outer layers.

I would like to note that the convenient and familiar grinder was not included in this list, since it is used with a diamond disc, which can lead to the destruction of the coating at the edges of the cut.

Disc nozzle for a drill for cutting metal

When using such a nozzle, you need to remember that the disc itself should only be with teeth. The main disadvantages are that you can only work on a flat surface and secure the sheet for processing.

If you need to correct the sheet already on the roof, this will not work. Second, the cuts can only be straight; it will be problematic to cut a semicircle. It is much more convenient for this purpose to purchase a nozzle such as a nibbler.

Drill bits for cutting metal

Having a good drill in the household, with the help of attachments, you can make a universal tool from it for all occasions. For example, a process such as cutting a piece of metal, even a small piece or strip, can become a whole problem. Of course, there are a large number of metal shears from different companies, and they will cut. But the edges of the sheet to be cut must be folded back, it is not possible to cut an oval or other figure with them. The grinder is also not suitable for this purpose, the cut will be large and you will have to remove the burrs in the cut area. To solve this problem, you can simply buy a drill attachment for cutting metal at any hardware store.

What is a drill bit for cutting metal

By design, this is such a gearbox that works on the principle of a matrix and a punch and practically punches such a kind of punch that works with a matrix and punches holes due to the transition of rotational movements into oscillatory movements.

Exploded view of a drill attachment for cutting metal

Works like a nibbler. As they say - all ingenious is simple. Of course, these are not electric scissors, but if you do not do the roofing work on a daily basis, this is a great option for a home workshop.

Work attachments on a drill for cutting metal

In this case, the width of the cut will turn out to be no more than 3 mm, the edges of the cut will remain without thermal effect, that is, the metal coating will not change its properties. The cutting itself will be carried out using a drill chuck, on which the device is fixed. Of course, the drill must have at least 2500 RPM per minute.

The thickness of the cut metal must be within the following limits:

stainless steel - 0.8 mm;
copper, brass, zinc-plated steel, zinc, plain sheet iron - 1.5 mm;
aluminum - 2 mm.

But, as with every tool, you need to get used to working with this attachment.

Types of attachments

All drill bits work according to the same principle. The only difference is in the thickness of the processed sheet. After work, the cut itself turns out to be smooth, without burrs. The only thing that may not allow cutting is the discrepancy between the nozzle and the drill in terms of the applied speed. The most used nozzles by Russian craftsmen are Sverchok, Steel Bober, SPARKY, EDMA Nibblex.

The nozzles are very versatile, their use has sufficient performance, the presence of a handle helps to control the cutting of all nozzles, the cut is of good quality, both pneumatic and electric drills can be used. They do not require special settings, you can make curly cuts, most importantly, the personal skill of the master.

Cricket nozzle

This is a scissor attachment for a drill for cutting metal. They are special nibbling scissors that can be used to cut both smooth and profiled sheets, as well as plastic and carbonate, which are also difficult to cut.

Sverchok attachment for metal cutting

When using this drill bit for cutting profiled and sheet metal, you can cut plastic up to 2 mm thick, as well as stainless steel up to 1.2 mm. They can also perform an internal cut, although for this you need to make a preliminary drilling.

It is very convenient to use for roofing works to cut the metal tiles. When cutting with "Cricket", deformation does not occur and the sheets do not require editing. Even if you need to cut a circle or other complex element for any purpose, this nozzle will cope with this task. The only thing that is required is the skill of the master. Speed 1500-2500 rpm, price 1900 rubles.

Steel beaver attachment

It is equipped with a replaceable die and a poisson. The difference from the previous nozzle is that the thickness of the sheet steel that this nozzle can cut is 1.8 mm, and the speed of the drill used should be in the range of 1500-3000 rpm.

The most beloved device of our craftsmen. Country of origin Bulgaria, differs as good quality, and at a democratic price.

The price of such a nozzle for a drill for cutting metal is in the region of 2000 thousand. The main technical characteristics include: working speed for the correct operation of the nozzle 3000 rpm, the thickness of the cut steel from 1.8 to 2 mm, with such parameters, the cutting speed is 2 m per minute.

Drill nibbler SPARKY

Of course, the Poisson is a very common part being replaced in these tools. It is sold in the same stores where the attachment itself is purchased. I would like to note that very often remarks appear on the Internet that, they say, a poisson for SPARKY costs 600 rubles, and a poisson for another nozzle is about 150 rubles, but that one is made in China. Yes, in China. But the tool of the global company BOSH is also mostly made in China, but this is why its quality is still the highest (of course, if you don't run into a fake). The point is in the applied technologies and quality acceptance. Therefore, the miser pays twice.

Types of equipment for metal cutting

You can cut a metal sheet or a more massive metal product using various equipment.

Angle grinder

This device is also known as the "grinder". It can be used to cut rebar, plate and other types of metal. This is the most popular equipment used for this purpose.

Metal circular saw

This saw allows you to make cuts at different angles and perform them with great accuracy. However, when using this equipment, the resulting cuts have a limited depth and a large amount of waste is generated.

Guillotine

This is a high-performance equipment for metal cutting, with the help of which workpieces of simple configuration are processed.

Bandsaw and jigsaw

This equipment allows you to make cuts at different angles. Both the jigsaw and the band saw, due to their design features, impose significant restrictions on the size of the products that need to be cut.

Hydraulic equipment

As mentioned above, drill bits, which are presented in a wide variety on the modern market, can also be used for cutting metal products.

Drill bits can also be used for cutting and other materials

Features of the use of drill bits

The working part of the punching nozzle

Using the drill bit, you can cut metal sheets of the following thicknesses:

made of aluminum - up to two millimeters;
made of copper, brass, sheet iron, zinc and galvanized steel - up to one and a half millimeters;
made of stainless steel - up to eight tenths of a millimeter.

Examples of cuts with a nozzle of galvanized sheet (0.55 mm) and aluminum (2 mm)

Benefits of using drill bits

Drill bits, when compared with such a popular metal cutting tool as a grinder, have a number of advantages.

The cut is of high quality.
When using a drill attachment for cutting metal, there is no need to purchase additional consumables, which significantly saves money.
The use of such a nozzle ensures high productivity of the cutting process.
Drill bits are highly versatile.
Due to the fact that this tool is equipped with a special handle, it is very convenient to perform the cutting process with it.
These attachments are suitable for both electric and pneumatic drills.
The convenience of these attachments is undeniable both in use and in maintenance.
With these tools, you can make cuts in almost any configuration.

Despite the simplicity of the design of such nozzles, their use requires certain skills and dexterity from the user.

Popular models and their areas of application

Modern models of drill bits allow cutting sheet metal not only in a straight line. With the help of such a convenient and easy-to-use device, you can also make curly cuts, which is often required when installing roof structures, ventilation ducts, as well as gutters and other elements of the drainage system.

Using such drill bits, cuts can be made in almost any spatial position. An equally important advantage of these attachments is that they do not require preliminary adjustment.

This attachment turns the drill into an electric shear that works on the principle of cutting, not nibbling.

Among the most popular models of drill bits for metal cutting on the domestic market are the following:

"Cricket" (from the "Enkor" company);
Sparky NP 1.8L;
EDMA NIBBLEX;
ACKO YT-160A.

The differences between the models of drill bits are not in the principle of their operation, but in the maximum thickness of the cut metal and a number of other technical characteristics. Modern models of drill bits allow you to get straight and neat cuts with sharp, smooth and unnoticed edges. In this case, the protective coating applied to the surface of the metal sheet is not damaged and fully retains all its functions.

"Cricket"

Scissor attachment "Cricket" is designed to operate from a pneumatic or electric drill (screwdriver) with a power of at least 420 W

1.5 mm - for steel sheet material;
1.2 mm - for stainless steel;
2 mm - for copper and aluminum, as well as polymeric materials.

With the "Cricket" drill attachment, you can cut sheet material in the horizontal and vertical planes, as well as make internal cuts on the sheet surface.

"Sverchok" works on the principle of nibbling scissors

It should be borne in mind that in the place of the sheet from which the internal cut will be made, it is necessary to pre-drill a hole.

"Steel beaver"

Metal cutting attachment "Steel beaver" is completed with a replaceable die and a punch

Among the technical characteristics of this type of drill attachment, it is necessary to highlight the following:

The efficiency of such a nozzle is ensured when the drill chuck rotates at a speed of 1500–3000 rpm.
The maximum workpiece thickness is 1.8 mm for conventional steel sheets, 2 mm for copper and aluminum sheets, 1.2 mm for stainless steel sheets.
The angle by which you can change the direction of the cut is 360 °.
The minimum cutting radius is 12 mm.

When deciding which tool to choose for cutting sheet metal - a jigsaw, a grinder or a drill bit - you should first of all evaluate the tasks for which they are needed.

Drill bits are a good option for DIYers and small construction crews. When the volume of work on sheet metal cutting is small, the use of such a nozzle is the best solution. When choosing this device, you should pay special attention to the fact that the characteristics of the drill, complete with which it will be used, correspond to the characteristics of the tool itself.
