Nozzle scissors on a drill cricket. Hot promotions in power tool accessories on aliexpress:

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 big amount 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. You should start cutting only when the drill has gained the required level of speed.

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. The cricket nozzle is often indispensable in the implementation roofing works. 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 a "cricket" you can also drill neat round holes of large diameters, including artistic cuts. If necessary, work can be carried out on horizontal and vertical surfaces. As an additional criterion, the cricket tip 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;
  • ease of maintenance and use;
  • 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 electric scissors. professional level. 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.

Being engaged in construction or repair work, almost everyone is faced with the need to cut any metal blank. To perform this procedure, you can use a grinder, cutter, hand shears for metal.

But what if it is necessary 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 that you can buy at any hardware store.

What are metal cutting tools?

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

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

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

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

In action cutting tool leads drill chuck, to which it is attached. It is worth noting that the nozzle can cut metal only if the number of revolutions of the drill is at least 2700 rpm.

Nozzle benefits

Compared with a grinder, a drill attachment has a large number of advantages.

However, despite all the advantages of the tool, in order to ensure high cutting quality, it is necessary to work with it. certain dexterity and skills.

Special nozzle "Cricket" on a drill for cutting metal

Hardware stores offer several types of accessories for drills for cutting metal.

Nozzle "Cricket". The "Cricket" device is a cutting (cutting) scissors that are able to perform an even cut. The tool is used for cutting not only smooth, but also profiled metal sheets.

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

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

With the help of the Cricket attachment, 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 it is required processing of metal tiles or corrugated board. After applying Cricket, the materials used will not be deformed, and the cut will turn out to be even and beautiful.

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

Nozzle "Steel beaver"

The device is designed for cutting flat and profile sheets (corrugated board, metal tiles). It has a cutting mechanism, the operation of which is similar to the processing of materials with punching shears.

During metalworking with the Steel Beaver tool sparks are not generated and not burned protective layer metal coating.

Main characteristics:

  • cutting is performed at a drill rotation speed of 1500–3 thousand rpm;
  • the maximum thickness of aluminum and copper sheet should be 2mm;
  • stainless steel sheets must have a thickness of not more than 1.2 mm;
  • the maximum thickness of the steel sheet can be up to 1.8mm;
  • changing the direction and angle of the cut - 360 degrees;
  • the minimum cutting radius is 12 mm.

Models of nozzles for a drill and their application

With special nozzles for drills, you can perform both straight and curved cuts. Do curly cuts for installing gutters drainage system or ventilation parts of the roof, cut in the vertical and horizontal direction.

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

In the construction market, nozzles for a drill are represented by several models:

  • ACCO YT-160A.
  • EDMA NIBBLEX.
  • Sparky NP 1,8 L.
  • "Cricket" from Enkor manufacturers.

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

After applying the devices, the edge is obtained sharp, smooth and not wrinkled. It is only necessary to ensure that the speed of the drill used matches 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 home crafters, 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.

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

The most common nozzles and their descriptions

There are several hundred different nozzles and they all differ from one another in some way. It is simply impossible to cover the entire range of goods, so let's start from the most "running" models that can replace your expensive tools. With their help, you can perform basic construction and Finishing work, process a variety of surfaces and materials. We do not take a drill and a "blade" into account, only additional accessories. Let's consider in more detail.

  1. Crowns. Unique nozzles for making holes in wood. An indispensable thing in the manufacture of furniture. They have different diameters and heights. As a result of the work, you get perfectly even 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).
  2. Nozzle "screwdriver". There is nothing easier than making a conventional screwdriver. It is enough to buy inexpensive cross-shaped and straight tips and you immediately have 2 types of screwdrivers. More precisely - 3 types, since there is also a percussion (perforating function on a drill).
  3. Metal brush-circle. Used for metal work (mainly), it is a metal bristle that is located around the shaft, and it, in turn, is mounted in the cartridge. This shape is made for maximum balance of the nozzle. When you turn on the device, the brush has a very high speed and removes all rust and bumps in seconds!
  4. Corolla. For mixing building mixtures, a specific nozzle is used in the form of a long screw and a large holder, which is inserted into the tool chuck. With something like this you can mix an excellent tile adhesive in a few minutes, mortar for laying bricks and whatever you want. Yes, even 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 nozzles are known to almost every builder and have gained immense popularity not only in the construction industry, but also in many household tasks.

Rarely used nozzles

  1. Jigsaw. Incredibly, a high-quality jigsaw can be obtained from an ordinary tool with a rotating chuck. This is an adapter nozzle that converts the revolutions of the cartridge into useful energy that launches a complex saw swing mechanism. As a result, you can process thick boards, and make the most complex patterns.
  2. Flexible shaft for drill or flexible drill. In fact, this is a standard nozzle, only it does not break when bent, but deforms without loss of strength. There is an opportunity to get to the most inaccessible places, for example, in the head of a car, when installing industrial transformers, and the like.
  3. Angle nozzle for a drill. There are several versions of this thing, but the most popular is the grinder. You get a high quality tool for metal cutting, polishing and grinding.
  4. "Cricket". Another rare attachment that allows you to make scissors for metal. Works with material up to 1.6 mm thick, which is simply amazing. You can cut any pattern you need - it is very easy and convenient to control the direction of the cut.

These nozzles are not always relevant, sometimes it's easier to buy the appropriate device and not mess with them. If you need to perform one-time work, it makes sense to purchase an inexpensive adapter or device to solve a particular problem.

Grinding and polishing

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

  1. Grinding nozzle for a drill. Designed to remove rust on metal, eliminate visible product defects, sharpen steel cuts and many other functions. Nozzles for a drill for grinding are rods on which abrasive nozzles are located. When the chuck is rotated, it accelerates to the same speed and is used as a grinding wheel. The abrasive can have different grain sizes.
  2. Nozzle for a drill for grinding wood. A similar item as for metal processing, but instead of an abrasive, a polyurethane, rubber, mineral (etc.) circle is installed, with which you can make the surface extremely smooth and without chips or needles.
  3. Nozzle on a drill 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 like a polishing machine. The only drawback is that the drill is much heavier, so it will be a little uncomfortable to hold it.
  4. Grinding sun. Another unusual fitting. It is a circle from which strips of sandpaper come out like rays. When the chuck rotates, the paper petals accelerate to high speed and grind any metal in a few seconds! The nozzle is short-lived, enough for a couple of hours of work, but very effective!

We have reviewed the most useful nozzles. Now the choice is yours: use these devices or buy expensive devices.

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

  1. Better cut surface quality.
  2. The device allows you to make a hole in the 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 nozzles allow you to work with both metals and plastic sheets of appropriate thickness.
  6. 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 220 V home electrical network.
  7. 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.
  8. 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, 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.

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. 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 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 effective work nozzles, the manufacturer recommends 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 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.

  1. 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.
  2. 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.
  3. Nozzles for Russian-made drills are practically not inferior in quality to foreign counterparts, while the price may differ significantly downwards.
  4. It is not recommended to purchase devices from your hands, you can buy defective goods for a lot of money.
  5. Tools should be stored in rooms where the possibility of metal oxidation due to high humidity will be excluded.
    6. (1 ratings, average: 5,00 out of 5)

It all started with the fact that I was going to change the slate roof to a metal tile and sheathe the house with 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 many different 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 standing nearby and hearing our dialogue with a friend wrote the address of the store and the name "cricket drill nozzle" on a piece of paper


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, uneven edges, already 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!
