Nozzle on a drill cutting scissors. Hot promotions in power tool accessories. Special nozzle "Cricket" on a drill for cutting metal

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

Nozzle on a drill "steel beaver"

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

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

The design of the nozzles on the drill

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

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

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

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

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

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

Metal cutting attachment

The nuances of using "cricket"

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

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

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

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

« steel beaver"in design and principle of operation is similar 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"

The need to cut any metal products is faced by almost every specialist involved in construction and repair work. Many professionals use a variety of tools for high-quality metal cutting, starting with a milling cutter, grinder and ending with hand scissors. But what to do if at the right time there are no such tools at hand, and it is extremely necessary to cut the metal. This process can be carried out using a conventional electric drill. Now in hardware stores for these purposes you can buy specialized nozzles for a drill for cutting metal.

What is a metal cutting drill bit?

By their own design features the nozzle resembles a punch or a cotter pin, which, due to the matrix, breaks through the metal with a large number of repeated movements. After that, strips of the required shape are formed in the workpiece. In the process of cutting, the effect on the metal occurs in a pointwise manner, which helps to preserve the integrity of the products as much as possible. A similar nozzle repeats the work.

With the help of a nozzle, metal can be processed with the following parameters:

aluminum with a thickness of products on average up to 2 mm;
stainless steel up to 0.8 mm;
brass, copper, galvanized steel, iron sheets, zinc with a thickness of up to 1.5 mm.

It should be remembered that the softer the material being processed, the greater its thickness can be.

Features of the nozzle

Before direct work, the nozzle is securely fixed in the drill (chuck), which drives it. The principle of operation is almost completely identical to the process of operation of electromechanical scissors, which perform straight and curly cuts without much difficulty. To ensure a high quality cut, you should correctly select the number of revolutions. For example, for a metal of small thickness, from 2700 to 3000 thousand revolutions is well suited. Start cutting only when the drill has dialed required level revolutions.

Typical types of nozzles for a drill

On the market you can find several models of nozzles for metal drills:

nozzle "cricket"(acts like a nibbling scissors) - used for cutting thin sheet metal. Consists of two special cutting heads. Nozzle "cricket" is often indispensable in the implementation of roofing work. For example, such as cutting metal tiles or corrugated board. Using such a nozzle allows you not to deform the material and get even and beautiful cuts. In contrast to cutting with a grinder, the nozzle is able to perform sharper, burr-free edges. With the help of the "cricket" you can also drill neat round holes large diameters, including artistic cuts. If necessary, work can be carried out on horizontal and vertical surfaces. As additional criterion the cricket nozzle helps to process the edges with special abrasive materials during the cut. The price of such an instrument is often in the range of 4000-7000 rubles;

nozzle "steel beaver"- for the most part, this type of nozzle is used when cutting profiled and flat sheets of metal. According to its principle of operation, the cutting mechanism of the nozzle itself very much resembles the processing of material using punching shears or a “guillotine”. In addition, using the nozzle "steel beaver" in the process of work, the protective layers of the metal coating of the sheets are not burned, and thus no sparks are formed. The use of a nozzle eliminates the risk of possible chips or deformation of the cut edges. This attachment can cut polycarbonate, aluminum or plastic. Distinctive characteristics of the nozzle are: rotation of the drill from 1500 to 3000 thousand revolutions, the minimum cut radius is 12 mm, the possibility of changing the cutting angle of 360 degrees, the processed thickness of materials - copper and aluminum 2 mm, stainless steel - no more than 1.2 mm , ordinary steel - up to 1.8 mm.

There are a large number of options for the execution of this tool from different manufacturers, however, the principle of operation is the same for all.

The main advantages of nozzles

As a rule, experts identify several main advantageous differences between nozzles for a drill and a grinder:

tool versatility;
simplicity in after-sales service and application;
high quality cut;
good performance;
the ability to make holes of any shape;
cost savings due to the absence of the need for additional Supplies in work;
ease of use of the equipment, achieved by equipping with a special handle;
the ability to work from a pneumatic or electric drill.

It should also not be forgotten that certain skills are required to ensure a high quality cut. Of course, unlike household or professional tools of complex configuration, you won’t have to adapt for a long time to work with a nozzle. Any beginner will be able to cut through up to 10 meters of metal in 1 hour. The attachment can be attached to any type of modern drill.

In general, you should not think that a drill attachment for cutting metal will be a full-fledged replacement for several tools at the same time. Unfortunately, the power of this equipment is not always enough in comparison with professional-level electric scissors. In addition, the supported thickness of 1.5 mm does not make it possible to carry out any really serious work.

If you do not take into account the degree of productivity of the tool, then the nozzle can be completely purchased to perform not too resource-intensive work. In such situations, the nozzle will significantly save a lot of time and money.

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 an alternative way to 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 at 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 little the best performance 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 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.

The price on the 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 recommends optimal frequency drill rotation at 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 both by 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.

It all started with the fact that I was going to change the slate roof to a metal tile and sheathe the house metal siding.

I went and bought everything I thought I needed. I am engaged in construction, but I have never worked with roofs, with painted galvanization either. Zero experience. But hands from where it is necessary to grow.

In general, the slate was removed, everything was prepared, sheets of metal tiles can be fixed. The roof is multi-pitched, a lot of trimming and fitting. As it seemed to me at that time, I would cut with an angle grinder, in the common people with a "grinder", with an ordinary cutting disc. And after the first attempt, doubt crept in, sparks flew in all directions, stuck to the coating and even burned it in places. It is no longer difficult to guess that at the place where the coating is broken, corrosion will appear very quickly and the meaning of replacing the roof will be irretrievably lost. I tried ordinary metal scissors, it's funny to remember how much time it would take me to go through all the corners, oblique cuts and fittings. Moreover, ordinary scissors are not at all designed for cutting metal tiles.

I started calling my friends. Friends explained to me that there are punching and cutting electric scissors that perfectly cope with such tasks. In the store where I arrived, they showed me a lot various models, everything would be fine, but the price turned out to be very biting. The cheapest 12.000 rubles. What's the point of buying them, what am I going to do with them? In the installation of plumbing and heating, (what I do) they have no use. In short, I was upset and, out of hopelessness, was about to fork out, when suddenly a man who was standing nearby and heard our dialogue with a friend wrote the address of the store and the name "nozzle for a drill" on a piece of paper nibblers for metal "Cricket"

We arrived, twisted, turned, listened to a brief oral instruction manual and bought it. The purchase cost 1250 rubles, that is, ten times cheaper!

In 3 days we covered 200 square meters of roofing and sheathed the house with metal siding. The nozzle exceeded all my expectations. First, put the nozzle on the screwdriver, (1800 rpm) the cutting speed is slow and the quality is not super, burrs, jagged edges, got upset. Then they put it on an electric drill, (3000 revolutions) heaven and earth, the edges are smooth and the speed is completely satisfied. It is convenient to work with an uneven and sharply convex surface, as well as adjust the degree of inclination. The cricket handle is independent of the drill and rotates 360 degrees. Cuts sheet metal up to 1.6 mm like paper. Any hole in the sheet, please enter a 12 mm hole and you're done! I tried to cut two sheets of galvanized 1.0 mm, that is, 2.0 mm at the same time, and it cuts very decently. I also liked that there are two heads on the nozzle, on any of which you can screw the handle, and after it becomes dull, do not immediately change the matrix, but only turn it 90 degrees and change the cutting edge. This is done in three movements, loosen the screw with a special key, turn the matrix, tighten the screw. And in this small, in my opinion, indispensable tool in everyday life, everything is as simple as one, two, three!
