Small nozzle with a name "Cricket" designed for installation on power tools - screwdrivers, drills, hammer drills. It is capable of cutting sheet metal, which allows you to expand the functionality of the tool and perform more operations with it than usual.

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

At the main device where it is installed "Cricket", the 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 have such power, such as a drill and hammer drill, as well as a screwdriver.

The length of the device 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-sided shaft, which has excellent adhesion and high strength compared to simple round shafts.

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

Drill head, "Sverchok" screwdriver on Aliexpress: the best sellers and stores

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

Or the hacksaw is not available, then you can use an electric drill with a special attachment 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.

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:

1. Higher quality of the cut surface.
2. The device allows you to make a hole in metal of any shape.
3. Significant savings Money, due to the lack of spending on consumables.
4. The tool is very easy to use.
5. Many attachments allow you to work with both metals and plastic sheets of the appropriate thickness.
6. When using a drill equipped with rechargeable battery, can be produced in places where it is not possible to connect to a home electrical network with a voltage of 220 V.
7. 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 cut sheet metal.
8. Low weight of the device.

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

Scissors

The scissors attachment on a drill for metal cutting is a device that converts the rotation of the drill chuck into reciprocating movements, which, thanks to a special matrix, knock out a strip 3.1 mm thick 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 necessary to cut stainless steel.
• 1.5 mm - for processing copper and brass.

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

"Cricket"

The "Cricket" attachment 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 and does not require 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 distinguished:

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

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

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 - pribluda of the "Sverchok" type, Russian production.

The device allows you to perform high-quality cutting of sheet aluminum with a thickness of up to 2 mm. Indispensable when working with roofing metal materials, since, unlike 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 a piece of aluminum, leaving the edges completely intact. The limitation on the maximum metal thickness, 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 pribluda 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 recommends the optimum rotational speed of the drill at 3,000 rpm.

Estimated cost of EDMA NIBBLEX on the Russian market is 5,000 rubles. The high quality of the device is confirmed by numerous tests as professional craftsmen and common people who purchase the device for home use.

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

Today there is a great variety of all kinds of tools, whose tasks include cutting and cutting thin sheet material. One way or another, they cope with their tasks, but they have one feature - universal metal scissors do not exist. Some devices are easily cut from flat sheet steel, others are perfect for stationary work, and still others, being a household tool, can barely cope with the task of cutting plasterboard profiles. The only exception is one device - cut-through scissors, one of the variants of which is the "cricket" drill attachment, which will be discussed in this article.

How the cricket nibbler works

It is quite simple to imagine the work of a nibbler - in fact, it can be compared to a chisel that makes breakdowns in metal at a high frequency. Another comparison is the modern electric jigsaw, in which the standard saw 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 you to use a tool of this type even for shape cutting of sheet metal. It is for this reason that modern builders use the cricket for cutting:

• profiled flooring;
• any smooth steel when it comes to high volume work.

These are not the only reasons why the drill cutter attachment has become widespread in the construction and renovation industry.

The advantages of this tool

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

Additionally, the following points can be highlighted as the advantages of a cutting metal drill bit.

• High productivity - a 1 m 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.
• That only is the opportunity to overcome almost any obstacle. Wave and various bends are not a problem at all - you can direct the torch movement not only left-right, but also up and down.
• According to the manufacturers, this tool is able to easily cope with metal up to 2 mm thick, which is quite enough for working 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 a built-in electric drive.

As for the shortcomings, the most significant is only one - it is almost impossible to achieve a perfectly straight cut. In principle, it is not needed, since the edges in most cases are overlapped either with another sheet of metal or with special elements. If you really try 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 metal, there are a couple of points that you need to watch out for when working with a 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 stick into the legs, and this may not even be felt on the hardened feet. Then suppurations and all the ensuing consequences begin. Closed shoes are the best when working with the tool.
• 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, one should not forget that small chips scattered throughout the yard corrodes quickly, and if they remain, for example, on paving slabs, then rust eats into it and spoils appearance cover. 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 according to 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.

Basically, 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 an intensive mode of operation without repairs and Maintenance for five years. By and large, we are not talking about so much money - a professional attachment can be purchased for about $ 30-50.

At the end of the topic, the "cricket" drill attachment, there is only one thing to add - to remind you that you can extend the life of any tool thanks to proper care for it. Every self-respecting master should clean his "breadwinners" at the end of work and monitor their technical condition. Naturally, do not forget about the careful attitude to the tool - hammering nails with a nozzle and generally using it for other purposes is simply wrong.

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

LBM - angle grinder "Bulgarian"

Mechanical cutting with a grinder, guillotine, circular saws or band saws is used in small farms and at medium-sized enterprises. The main disadvantage of mechanical cutting is the rough effect on the material. As for strengths, then we can note the efficiency and high precision of processing.

Types and application of drill bits

Many people who started repairs faced the replacement of a drill bit with a drill. Correctly selected tool allows you to get rid of many problems, for example, from grinding work. According to its external characteristics, the drill bit resembles a punch. Metal cutting is carried out by means of a matrix and circular rotary movements.

Drill bit "Cricket"

Kinds:

Various goods are sold in hardware stores, among which are:

• The Cricket attachment is a cutting shears. "Cricket" makes an even cut on smooth and profile metal. It should be noted that "Cricket" can be used for processing polycarbonate or plastic. Sverchok is ideal for cutting sheet steel and profiles. In addition, the drill bit 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. The Cricket is considered versatile because it allows horizontal, vertical, and internal cuts. The accessory is considered indispensable in roofing work, especially when the roof is covered with a profile or metal tile.

• "Steel beaver" is used for cutting corrugated board, metal tiles and other flat profile sheets. "Steel beaver" copies the scheme of the cutting shears, however, during processing it does not generate sparks and does not burn the protective coating. The attachment is capable of efficiently processing different metal sheets, but not more than 2 mm;
• Special attachments allow you to perform different types cutting. For example, curved and curved ones are often installed on a drill when it is necessary to replace the gutters of the gutter system or when repairing ventilation parts. In the construction markets, the following types of attachments are common: ASKO YT-160A, EDMA NIBBEL and Sparky NP 1,8 L. The listed models are easy to install the apparatus and do not have significant differences in the field of application. The difference between them is only in the thickness of the processed sheet. It is better to check this parameter with the seller.

Grinder and circular saw attachments

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

Grinder attachments turn it into a versatile tool

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

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

Circular slab discs fall into two categories: discs for soft materials (wood, plastic, tiles, etc.) and metal. Cutting attachments 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 there are specialized attachments on the construction market, for example, under laminate or plastic.

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

Difference between drill and other tools

The drill is not suitable for efficiently cutting thick metal sheets. The maximum she can cut is a steel sheet 2.5 mm thick. Among the hand tools, the grinder stands out; this tool is able to efficiently process metal workpieces of almost any thickness.

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

Video: Attachment H1 on the "grinder"

This video shows a useful attachment for a screwdriver or for an electric drill. The author recently purchased this tool for cutting sheet metal, tin, 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, the key is included. Hexagon on one side, 12 key on the other.

How does a screwdriver attachment work?

The shank is screwed to the chuck, the working part cuts the metal. The handle itself is unscrewed. And in the place where she was, there is another knife. If the nuts are loosened, the knives can be turned to any angle. They rotate on their axis. They are also fixed with the same nuts. The attachment is very simple. The knives are driven by an eccentric. Excellent for cutting sheet metal.
The video shows how it is cut a metal sheet 1.5 mm thick.

This nozzle is for cutting thin profiled metal up to 0.8 millimeters thick. The kit includes a replaceable die, a replaceable punch, 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 is dull, we unscrew the handle, turn over the nozzle, set it on the other side. We insert into the drill, fix. You can start cutting metal.
As shown in the video, the cut is without deformation, the speed is decent.
There is a myth that the grinder cuts faster. Verification shows that this is not the case. The grinder is slightly inferior in speed to the drill attachment.
The most important thing is that the cut is very even, smooth, without snags. Grinder cut with burnt coating, burnt zinc. There are many sparks during cutting that strike the paintwork on the metal. If sparks from a grinder hit the polymer coating, the surface may become rusty the next season. Every self-respecting manufacturer categorically prohibits cutting with a grinder. In case of violation of the cutting technology, it is canceled from the warranty.
There are disadvantages when using the attachment. You have to work with metal using both hands. On the roof, this is problematic. But on the other hand, it will perfectly cope with your roof and with the roof of your neighbor.

The Jigsaw is a drill bit designed and manufactured to the highest standards, using the experience of the best British craftsmen and engineers. Cuts cleaner, faster and longer. It is mounted on any drill: electric, pneumatic or cordless with a chuck up to 18 millimeters in size at a rotation speed of one thousand five hundred to three thousand revolutions per minute.
Pre-drilling a 12mm hole will allow you to cut almost any shape into the material. The jigsaw cuts materials at a speed of 1.5 meters per minute with a drill speed of 2500 rpm.
cuts stainless steel up to 18th density class, mild mild steel up to 16th density class, copper, brass, aluminum, corrugated plastic, plexiglass and fiberglass up to 14th density class.

The tool performs straight cut even the softest materials, allowing you to get any shape with neat edges.
After cutting, the workpiece does not need to be leveled and filed. You will be pleasantly surprised by the durability of these heads. It gives you maximum agility.

If you have ever spent hours working with a hacksaw or the room is filled with an unpleasant smell from a grinder, then 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 while performing roofing, plumbing, bodywork, heating and ventilation work. The patented specially shaped cutter facilitates roofing and cladding work without damaging the material profile.
