Doing 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 protective layers products are kept 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 the protective layer of the metal coating is not burned.

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. Make 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.

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:

  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 home electrical network voltage 220 V.
  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 with a drill engine speed of 1500 to 3000 rpm.

"Beaver"

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

The beaver has 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 the effective operation of the nozzle, the manufacturer recommended the optimal drill speed of 3,000 rpm.

The estimated cost of EDMA NIBBLEX in the Russian market is 5,000 rubles. The high quality of the device is confirmed by numerous tests 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)

For repair and construction work, it is necessary to periodically cut the metal. It is not always possible or expedient to purchase special expensive equipment. In such cases, a nozzle on a drill for cutting metal can help out.

Special equipment for metal cutting

In production and construction, it is necessary to regularly cut metal sheets, cut holes in them, cutouts of various shapes.

Many types of tools and equipment can handle such tasks:

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

Nozzle on a drill "steel beaver"

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

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

The design of the nozzles on the drill

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

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

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

The nozzle can 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 a metal surface and will not damage the polymer coating of the material with sparks.
  • The lightness of the tool. There is no need to put in a lot of effort.
  • Drill and screwdriver compatible. There is no need to purchase an extra tool.
  • Price. Much cheaper than special equipment for cutting metal rolled products, and also saves money on the purchase consumable type of cutting discs on the grinder.
  • Easy to use. Easily installed on the cartridge, and also easily removed.
  • Performance. With the help of the "cricket" you can quickly cut the material.
  • Convenience. Thanks to its shape, it allows you to hold the tool at any angle.
  • Ability to cut holes and cuts of any shape.
  • Versatility. Suitable not only for flat sheets of metal, but also for profiled ones.

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

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

The "steel beaver" is similar in design and principle of operation to the "cricket". It also does a good job of cutting sheet metal. Curvilinear cuts are made with a minimum radius of up to 12 mm. The difference is that the metal can be thicker - stainless steel up to 1.2 mm.

And also you need to take into account that when working with these nozzles, a lot of metal chips are formed.

Safety

Regardless of the brand of drill and nozzle, their prices and characteristics, it is very important to observe safety precautions.

This will prevent injury and damage to the material.

  • Wear protective goggles and gloves when operating the drill.
  • Before starting work, it is important to check the fastening of the nozzle.
  • Be sure to check whether the material to be cut is well fixed.
  • The drill must be held with two hands for special holders.
  • When working with a metal cutting attachment, constantly remove falling chips. For example, when installing a roof, a large amount 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 pay attention to drill nozzles.

Video: Nozzle-scissors for cutting "Cricket"

Need to 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 the drill and the "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 a 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 cartridge is rotated, it accelerates to the same speed and is used as 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.
