Hand tools and attachments for metal cutting. Types and application of attachments for a drill for cutting metal Attachment for a drill, scissors for metal

With the need to cut any metal products almost every specialist involved in construction and repair work encounters. Many professionals use a variety of tools for high-quality metal cuts, from cutters, grinders and ending with hand scissors. But what to do if at the right moment 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 purchase specialized drill bits for cutting metal.

What is a metal drill attachment?

According to their design features the nozzle resembles a punch or cotter pin, which, due to the matrix, penetrates the metal big amount repeated movements. After that, strips of the required shape are formed in the workpiece. In the process of cutting, the impact on the metal occurs in a point manner, which helps to preserve the integrity of the products as much as possible. This nozzle repeats the job.

Using a nozzle, you can process metal with the following parameters:

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

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

Features of the work of the nozzle

Before direct work, the nozzle is securely fixed in the drill (chuck), which activates 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, the number of revolutions should be correctly selected. For example, for 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 speed.

Typical types of drill bits

There are several models of drill bits for metal on the market:

  • cricket nozzle(acts like a nibbler) - used for cutting thin sheet metal. Consists of two special cutting heads. The cricket nozzle is often indispensable for roofing work. For example, such as cutting metal tiles or corrugated board. The use of such a nozzle allows you not to deform the material and get even and beautiful cuts. Unlike cutting with a grinder, the nozzle is capable of making edges that are sharper without burrs. The cricket can also be used to drill neat round holes 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;

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

There are a wide variety of options for performing this instrument from different manufacturers however, the principle of operation is the same for everyone.

The main advantages of attachments

As a rule, experts identify several main advantageous differences between drill bits and grinders:

  • versatility of the tool;
  • simplicity in service and application;
  • high cut quality;
  • good performance;
  • the ability to make holes of any shape;
  • cost savings due to the absence of the need to use additional consumables in the 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 don't have to adapt for a long time to work with the attachment. Any beginner can easily cut through up to 10 meters of metal in 1 hour. The attachment can be attached to any type of modern drill.

In general, do 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-grade electric scissors. In addition, the supported thickness of 1.5 mm does not allow for 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 for performing not too resource-intensive work. In such situations, the nozzle will significantly save a lot of time and money.

Who hasn’t encountered the need to cut a metal part during repairs? Among the masters, most likely there is no person who would refuse a powerful portable instrument... In most cases, it is used:

  • grinder disc;
  • milling unit;
  • scissors for cutting metal.

But the modern market for power tools does not stand still, and now there is a drill attachment for cutting metal.

Various types of cutters, as a result of repeated repeated movements, cut metal using a matrix. As a result, durable metal lends itself to processing. Thus, we cut, punch holes or grind a metal surface. Point impacts allow you to work accurately without disturbing the structure of the elements. In addition, the natural protective layer of the product.

Using nozzles, you can act on the following metals:

  • 2mm aluminum plates;
  • copper, brass, iron, zinc and steel elements;
  • galvanized parts 1.5 mm thick;
  • stainless steel 0.8 mm thick.

Using a drill

It's no secret that a drill can be used not only as a drill, but also as a multifunctional tool. There is a whole range of different devices that facilitate the work of the worker.

For example:

  • cutter for metal for a drill, avoids monotonous manual work with a file;
  • scissors attachment on a drill provides the ability to cut metal sheets and elements;

  • drill bit for cutting metal tiles in turn helps to accurately cut sheet metal roofing at any angle.

Working with this kit takes some skill, but over time you will realize the benefits of this method.

Let's take a closer look at each option.

For cutting tiles

Another name for this drill bit is cricket. The set can be used both for smooth surfaces and for profiled iron sheets. The advantage of this cutter is the ability to create an even cut, without burrs and irregularities.

The cricket drill attachment is convenient to use for:

  • cutting thin-sheet products;
  • cutting out parts from metal sheets.

Since its application does not depend on the spatial arrangement, you can easily cut a horizontal and even vertical sheet.

Scissors attachment

Of all the nozzles presented, this one is the least similar to a drill. It turns the drill into an electric shear, not a nibbler. They work according to the principle straight cut cutting metal with sharp edges using mechanical force. This is a rougher method for cutting metal and plastic. Such scissors perform only a straight cut; it is very difficult to change its direction during operation.

This set is more suitable for cordless tools.

Milling cutter

In another way, this nozzle is called roller cutter. It is designed for processing wood and metal products:

  • a roller cutter replaces a file;
  • significantly speeds up the grinding process;
  • eliminates defects.

One set can include cutters different shapes Thus, the most suitable attachment can be selected for each specific situation. Some of them practically do not differ externally from the drill.

Metal crowns

In addition to the basic tips, there are other devices, for example, a metal crown. This is a special drill designed for making wide holes.... Its use is due to the need to lay communications. The downside of a metal crown is its roughness: the edges of the hole made require additional processing. It is in such cases that the roller cutter comes into play.

The set of crowns can include both simple and diamond-coated edges. They can be used to drill concrete floors and thick a metal sheet.

Riveter

An attachment such as a riveter on a drill is different from a conventional cutter or cutter. It is used to connect or fasten with small rivets. Riveting is a rather tedious process if done by hand. In addition, you will have to use several conventional riveting tools at once. That is why riveting with a drill and riveter is very popular among builders.

A peculiar method of fastening requires some preparation... Special holes are pre-drilled in the details using conventional drills. Riveted parts are securely connected to each other, forming a strong connection.

The drill attachment helps to quickly and efficiently process metal without special expensive machines. They can be used with different kinds drills, but its power should not be lower than 2700 rpm. Of course, a drill is not always capable of replacing professional tools, but for inconstant renovation works it fits perfectly. Another plus is the ease of use: you do not need to spend a lot of time to master any attachment.

When performing construction or repair work, it is often necessary to cut a metal workpiece. To do this, you should use special equipment in the form of a cutter, grinder or. However, it is not always at hand. To cope with this task, you can use a drill attachment for cutting metal, which will cut a product of small thickness.

Many craftsmen are accustomed to using a drill for its intended purpose, namely for drilling holes. But not everyone knows that this tool can be turned into a multifunctional device, supplementing it with special attachments, fixtures and stands, which will make the drill universal and indispensable in any work.

With the help of special attachments for a drill, which can be bought at any specialized store on affordable price, it is possible to carry out drilling of holes of all possible diameters, cutting, grinding, polishing, twisting, mixing and milling. There is also a pump attachment for a drill designed for pumping liquid. The attachment for plucking chickens is simply irreplaceable in the household. With the correct and competent use of additional attachments, the result will not be of the worst quality, as with the use of a special single-purpose device, but the cost of such a universal tool will be several times lower.

By design, all existing attachments are divided into:

  • accessories for drilling holes and crowns;
  • scissor attachments for metal cutting;
  • stops;
  • corner fixtures;
  • grinding and polishing attachments;
  • equipment for milling wood and metal;
  • sharpening devices;
  • feathering nozzles.


When working with any drill attachment, you must follow the safety rules:

  • the equipment must be securely fixed in the tool holder;
  • the drill must be held with two hands, which is especially important for powerful models;
  • constantly adjust the pressure of the tool;
  • work in personal protective equipment;
  • after completing work for several minutes, do not touch the drill to avoid burns.

What are metal cutting drill bits

Equipped with a special attachment for cutting metal conventional drill turns into a punch or cotter pin. The device penetrates a metal product due to the implementation of numerous reciprocating movements along the inner cavity of the matrix. As a result, a straight cut line with a width of 3.1 mm is formed, while maintaining a protective layer on the surface of the metal sheet.

Important! The maximum efficiency of the nozzle is achieved only when working with an electric drill, the rotation frequency of the chuck of which is at least 2700 rpm.


The metal drill attachment can handle cutting such metal products:

  • aluminum, up to 2 mm thick;
  • made of brass, copper, zinc, galvanized steel and sheet iron, up to 1.5 mm thick;
  • made of stainless steel, up to 0.8 mm thick.

Using a drill bit for cutting metal has a number of advantages:

  • the cut is of high quality;
  • there is no need for the constant purchase of consumables, which saves financial resources;
  • high productivity is provided when cutting metal;
  • versatility of the device;
  • the equipment is convenient and easy to use and maintain;
  • the nozzle can be used for electric and pneumatic drills;
  • using the attachment, you can make cuts of any configuration.


Despite all of the above advantages, in order to get a high quality cut, some skills and dexterity are required to work.

Popular attachment models

Today there is a large number of various models of drill bits, thanks to which you can not only cut metal in a straight line, but also make curly cuts. This is necessary when installing ventilation ducts, roof structures, gutters. The use of the attachment allows you to cut in any position without making preliminary adjustments.

Types of attachments:

  • the punching nozzle "Steel beaver" is used for cutting metal tiles, corrugated board and any flat profile sheets;
  • universal nozzle "Cricket" is used for cutting profile metal, polycarbonate and plastic;
  • special attachments for making curved and curved cuts are represented by the EDMA Nibbek, ACRO YT-160 A, Sparky NP 1,8 L models, which differ in the thickness of the processed sheet.


Drill scissor attachment"Steel beaver"

The classic drill bit for cutting metal tiles and any flat metal sheets in the form of a freely rotating shaft in a bearing with a fixed eccentric works on the principle of a crank mechanism with the difference that energy is supplied here for rotation.

A full-fledged nesting tool has a support part located on the bed and a movable part connected to an eccentric. It is the moving part that makes reciprocating movements during the rotation of the shaft. Mandatory element design is a handle, which is fixed perpendicular to the axis of rotation of the spindle. As the load increases, a reactive torque arises, due to which the drill moves relative to the bit.

It should be remembered that the tool must be positioned strictly vertically relative to the workpiece when cutting. Failure to do so could result in damage to the product and injury to the operator.

The device resembles a metal scissors. The drill bit is used for cutting flat products or profiled sheets with large bends. The cutting line is easy to control. During the operation of the tool, the protective layer of the coating is not burnt, which excludes the formation of sparks and the likelihood of burrs. You can perform continuous cutting of a product of any length. You can buy a drill attachment for cutting metal tiles and flat metal sheets for 1600 rubles.


Using the "Steel beaver" attachment for the drill, you can make a figured cutout for the installation of ventilation elements of the roof or gutter

The sheet is cut at a drill speed of 1500-3000 rpm. The cutting angle is 360 degrees, the minimum radius is 12 mm. With the Steel Beaver attachment, you can cut:

  • copper or aluminum sheet 2 mm thick;
  • steel - no more than 1.8 mm;
  • from stainless steel - up to 1.2 mm,

Helpful advice! To cut a profiled sheet with small-diameter bends, use the Sverchok-type shears.

Drill bit "Cricket"

The Sverchok nibbler got its name from the characteristic noise during operation of the device. The attachment is similar to the previous model, but has a different design of the working element, consisting of two cutting heads. The principle of operation of the "Cricket" attachment is similar to an office punch. Neat holes are squeezed out in metal with oscillatory movements of the cylindrical striker with a high frequency. Thanks to translational movements along the marked line, it is possible to obtain an even cut.


The Sverchok scissor attachment is used for cutting thin metal and profiled sheets, and polymer thin-sheet products up to 2 mm thick. Work can be carried out horizontally and vertically. Thanks to the ability of the tool to rotate 360 ​​degrees. you can drill large round holes and make artistic cuts. You can buy a drill bit for cutting metal "Cricket" for an average of 1500-4000 rubles.

The tool can cut metal with stiffeners and various profile stampings in two ways. The first option involves repeating the surface of the profile, bending around the edges. Used for products with a medium bend radius. For cutting metal tiles, another cutting option is used, according to which the tool moves along the stiffeners without bending around the sheet profile.

Before you buy the "Cricket" drill bit, you should take into account the main drawback of the tool. Due to the fact that the nozzle punch has a diameter of several millimeters, when cutting the product, a cut of a certain width is formed, which leads to certain material consumption. The result is metal shavings with sharp edges in the shape of a crescent, which must be disposed of immediately for safety reasons.

Helpful advice! Do not wear soft shoes when working with the tool.


Drill attachment "Cricket" does not require adjustment, easy to use and maintain

One of the most popular models is the Cricket scissor attachment for metal up to 1.6 mm Enkor 14210. The tool is able to cut a fairly thick metal sheet in a straight or curved direction. You can buy a drill attachment for cutting metal for 1300 rubles. The main feature of the tooling is that during the cutting process, a track is formed with a width of only 1.6 mm, which provides a fairly good level of material savings.

The device can be installed not only on a drill, but also on a screwdriver. The metal cutting attachment is lightweight, which does not add to the weight of the electrical appliance. The kit includes a replaceable handle, thanks to which the accuracy of the work is increased. The device has a low noise level due to its special design, which makes it more comfortable to work with.

Drill attachment for sharpening drills

This device consists of a plastic case, inside which a special shaped emery wheel rotates. It is he who allows you to form the required sharpening angle on the working part of the tool. The circle is mounted on a shaft, which is connected to the drill by a special coupling. It is activated when the tool is turned on.

Many modern models have an end cover on the body, in which holes of different diameters are located for sharpening drills of different sizes. These holes are made in such a way that the sharpening element is in contact with the emery wheel in a certain position.

The principle of operation of the sharpening attachment is simple - when the drill is turned on, the chuck rotates the grindstone located inside

The drill sharpening process is performed as follows. The product is inserted by the cutting part into the hole of the nozzle of the corresponding diameter. After starting the drill, the emery wheel begins to rotate, sharpening half of the drill part. Then the product is turned over in the hole by 180 degrees, and the procedure is repeated. This sequence of actions is performed several times until the required parameters of the cutting part of the drill are achieved.

A drill attachment for sharpening drills, which can be bought for an average of 350-500 rubles, has 15 holes with diameters from 3.5 to 10 mm. Products can be sharpened at an angle of 180 degrees thanks to the special shape of the stone. Simple construction the device allows you to perform work quickly and without special skills.

However, it should be remembered that the device is intended for sharpening sagging cutting edges. For a full-fledged sharpening of heavily worn products, an emery wheel will not last long.

Helpful advice! When buying an accessory of a certain model, you should take into account the diameter of the drill chuck.

There is also another type of additive. This is a drill attachment for sharpening knives and scissors, which is presented in the form of two emery wheels set on a shaft and located at a certain distance from each other. The price of such a device is about 250 rubles.


The attachment for and scissors for the drill is easy to operate, does not require special skills to use it

Drill attachment for grinding

With the help of a grinding attachment on a drill, old coatings, corrosion, chipping, and scale are removed from the surface of the product. It is used for grinding glass edges, metal parts and other materials. Thanks to the small size of the tool, hard-to-reach areas can be treated. The average cost of a product is 500 rubles.

Grinding drill bits are used for preliminary rough preparation of the substrate for future polishing. It is made in the form of a rod on which the grinding material is fixed in the form of a brush or sandpaper. There are various types of such devices that are used for specific tasks.

A cup attachment for a drill for grinding wood or other material is represented by a rod fixed to a chuck and a cup-shaped body filled with light or stiff bristles. The body is made of metal or durable and lightweight plastic. Typically this nozzle is used to remove old coating or corrosion from a surface.


Another variation is the disc attachment for grinding metal, where the bristles of the grinding material in the form of a brass brush or steel wire are directed towards the edges of the disc from its center. Use this additive very carefully, as it can easily damage the coating. The plate nozzle has a movable or fixed rod, which is fixed to the chuck. Sandpaper is attached to it with Velcro.

Helpful advice! It is better to purchase nozzles with a movable rod, which allows you to adjust the angle of inclination of the drill, while smoothly following the contours of the material.

A flap or fan sanding nozzle is represented by a rod on which pieces of sandpaper or other abrasive material are fixed. It is used for performing radius grinding or surface finishing with complex profiles. It can also be used for grinding holes, like carbide cutters or cutters, which work like a file.

Grinding abrasive stones mounted on the stem are used for removing sag, burrs, boring holes or leveling a weld.


Drill bits for polishing

After sanding, the base must be given smooth surface... This is done by polishing using special attachments. They can be made of felt, wool, foam or felt. According to the degree of softness, they can be hard, soft, super soft and embossed. According to the method of attachment, nozzles with a stem, with Velcro and with a retainer are distinguished. For polishing discs, fan or disc nozzles, end fittings are used for the holes. The average price of the product is 250-300 rubles.

Do not press the attachment too much against the surface to high temperature do not burn the paint.

Drill attachment for plucking birds

Plucking poultry is a laborious process, especially when several carcasses need to be processed. Therefore, many farmers were constantly in search of new solutions not only to facilitate work, but also to reduce the total time. For this purpose, the Feather Drill Bit has been specially developed, which removes feathers from the bird in a matter of minutes. It is similar to a dishwashing brush, except that silicone fingers protrude with bristles, which, when the shaft rotates, pull feathers out of the carcass. At the same time, the bird is brought up on different sides.

A drill attachment for plucking a bird, which can be bought for an average of 1,500 rubles. processes poultry carcasses in just 2-3 minutes, without leaving a single feather. The result is smooth, intact skin. The device is effective not only for processing chickens, but also gives good result when plucking geese. The drill attachment can be used not only for fresh, but also for frozen poultry.


Helpful advice! It is not recommended to scald the carcass with boiling water before using the nozzle, which will reduce the efficiency of the processing process.

The main advantages of a feather drill bit, which you can buy in any specialized store, are speed, simplicity and mobility of use, which does not require certain skills and additional processing of the carcass before plucking. A significant disadvantage of the device is that after this mechanical process, damage remains on the carcass, which worsens it. appearance... Therefore, if the bird is intended for sale, it should be plucked manually.

Other types of attachments

When it is not possible to make a hole in the usual way, you need to use an angle drill bit. The working head of such a device can be rotated under different angles relative to the axis of rotation of the drill chuck. The main disadvantage of the tooling is the increased risk of drill failure. Therefore, the most popular is the 90-degree angle drill attachment, which is fixed on the drill neck. The price of the product is on average 800 rubles.

This is a simple and optimal solution to avoid the purchase of expensive specialized power tools.

There are many ways to process metal products, both industrial and manual; for this, various tools are used, including a drill attachment for cutting metal.

In contact with

Types of processing

Once upon a time, the only way to process metal products was, but with the development of technical progress, people invented more and more new methods, and now we have a fairly rich selection of such means.

All of them can be divided into two main groups:

  • thermal;
  • mechanical.

Each method has its own advantages, and each requires its own toolbox.

Cut while it's hot

In thermal cutting, the cut is made using high temperatures. The following types of such processing are known:

  1. Gas.
  2. Gas-electric.
  3. Plasma.

Gas causes the cut by burning in oxygen, which is jetted to the site of the intended cut. Melting does not occur - the material remains hard, due to which the cut is smooth.

There are also oxygen-flux and oxygen-lance options. In the first case, a flux additive is supplied to the cut site together with oxygen, which exerts a chemical, thermal or abrasive effect on the material, which facilitates the cutting process. With the oxygen-lance variety, the required temperature parameters are provided by the combustion of a steel tube through which oxygen passes.

The gas-electric method involves the use of electricity and includes two types of cutting:

  • air-arc - the melt is removed by an air jet supplied under high pressure;
  • oxygen-arc, when metal splashes from a material heated by electricity are burned in an oxygen stream, and the scale is blown away from the cut.

Gas techniques are inexpensive, relatively easy to use, but do not provide a high quality result: after them, additional processing of the cut edges is required.

Plasma treatment is carried out using a plasma torch that creates a plasma jet with heating from 5000 to 30,000 degrees. The latter method has a number of advantages over the previously mentioned ones:

  1. The versatility of the application of the technique.
  2. High cutting speed and precision.
  3. The ability to cut along a complex curved contour.
  4. Higher level of environmental safety.

Among the disadvantages this method can be attributed to the high cost of equipment and the complexity of its maintenance, the noise of the process, the impossibility of processing large-sized products with a thickness of more than 8 - 10 cm.

Important! when carrying out heat treatment, it is necessary to observe safety precautions, protecting the face and hands from sparks and hot splashes.

Harder than iron

The mechanical version is much more accessible than the thermal one in everyday life and involves processing with tools that have a higher hardness in comparison with it, the use of which requires quite significant physical efforts.

It can be:

  1. Scissors.
  2. Accessories for electric drills.

When cutting metal sheets, the first type of tool is usually used. The following types of scissors are known:

  • hand-held metal shears;
  • splined, powered by an electric motor;
  • guillotine - manual and mechanical type.

The guillotine view is equipped with a single oblique blade that moves in the same plane at an angle, so that you can work with less force than when working with conventional roofing shears.

The saws have an electric drive and are divided into:

  • saber;
  • disk;
  • angle grinders.

Reciprocating saws are equipped with a set of saw blades with a length of 100 to 300 mm, moving along a reciprocating path. A good eye is required when working with them.

The cutting part of a circular saw is a disc, the diameter of which primarily determines what type of work can be performed with its help - the larger it is, the more varied they are.

  1. TurboShear MALCO TSCM EV - used for profiled sheets up to 0.6 mm thick. Telescopic clamp and shank provide a secure fit. Lightweight body - aluminum, knives - made of high-strength steel. The design features provide the ability to rotate to any angle.
  2. TurboShear (slotted) MALCO TSMD EV - suitable for cutting metal products up to 1.2 mm and cutting corners up to 90 degrees. Provides a perfectly straight cut line on both sides.
  3. Black & Decker MTS04 - designed for grinding. Also, this drill attachment is suitable for cutting, wood, plastic. The tool assumes use for repair and construction work in everyday life.
  4. TurboShear MALCO TS1 EV - for cutting steel sheets up to 1 mm thick. The attachment is provided by the shank. Aluminum body. Carbon steel knives. Working with this part is only possible with both hands.
  5. Scissors NP 1,8 SPARKY 181874 - will fit any model of electric drill. Able to perform linear and radius cuts, it can cut unalloyed steel.

Useful video: drill attachment for cutting metal

The use of the above devices allows you to significantly expand the scope of the tool, making it universal. However, it cannot completely replace saws, scissors and a grinder.

Various attachments for equipment can replace expensive counterparts. For example, a grinding disc attached to a screwdriver will brilliantly perform the functions of a grinder. In this article, a drill attachment for cutting metal, its advantages and basic models will be considered.

All existing gadgets, mounted on rotating heads of drills or screwdrivers, are divided by purpose into:

  • grinding;
  • polishing;
  • drilling at an angle;
  • sharpening;
  • feather-removable;
  • drilling holes;
  • cutting.

The last group is the subject of consideration.

Unlike cutting discs of a grinder, attachments for a screwdriver or drill cut the workpiece more delicately without deforming the coating of the material. The accessory is attached to the chuck of the power tool and rotated by pressing the "Start" button.

An important point - the considered metal nozzles are not compatible with every drill. The frequency of rotation of the latter should be at least 2700 rpm.

Advantages and disadvantages of using

The attachment is easy to put on the chuck and remove after work. In addition, the user discovers other advantages of using the equipment, including:

  • evenness of the cut;
  • no burrs on the workpiece;
  • comfort of work;
  • ease of use and installation;
  • no need for additional adjustment;
  • increase in productivity;
  • compatibility of known nozzles with an electric or pneumatic drill;
  • ease of maintenance;
  • the ability to cut holes.

The attachments for cutting sheet metal, aluminum, steel have only two drawbacks. First, you need to get used to them. Over time, even a beginner in the construction and repair business will master a simple device and learn how to work effectively with it.

The second disadvantage is the need to work with two hands. This complicates the work, for example, when installing a roof, if drill bits are used specifically for cutting metal tiles.

This is due to the fact that upper layer the roof covering is protected from above by a polymer that is unstable to high temperatures.

A working grinder inevitably heats up, so a polymer layer melts at the cut points, and then a zinc coating. Moreover, sparks flying in different directions will increase the area of ​​damage. The result is disappointing - deformation of sheet metal, the possibility of rust. Therefore, for sensitive materials it is better to look at the nozzle.

The principle of operation of removable elements

The rig has a shank screwed to the working part of the drill or screwdriver. The nozzle is fixed with the same nuts that held the drill or bit for self-tapping screws. Since the part to be fixed is rounded, you can turn the fixture at a convenient angle.

The knives that cut thin sheet metal are driven by an eccentric. The modified tool is ready for use immediately after attaching the removable part. After cutting the blanks, the screwdriver bits are removed, cleaned of chips, stored in the original packaging.

Overview of popular fixtures

"Cricket"

Experienced construction masters have come across two names of attachments - "Cricket" and "Beaver". More about each - below.

"Cricket" by the principle of action resembles a nibbler (cutting). Thanks to their two cutting heads, they perform straight cut not only on smooth workpieces, but also on profile ones. Also, with their help, it is easy to cut plastic, polycarbonate.

Maximum permissible cutting thickness:

  • sheet steel - 1.5 mm;
  • stainless steel - 1.2 mm;
  • copper, aluminum - 2 mm;
  • plastic blanks - 2 mm.

The scope of application of the Sverchok attachment is extensive. Being versatile, it allows you to perform operations on a horizontal, vertical surface, and to perform an internal cut. Nibblers for a drill process corrugated board and metal tiles, are used for cutting sheet metal and coarser materials of small thickness.

After work, the user will notice a smooth cut without burrs, notches, mark the integrity of the coating. For the durability of the nozzle, it is worth considering the manufacturer's recommendations. In particular, the minimum rotational speed of the drill is 1500 rpm, the maximum is 3000 rpm.

"Steel beaver"

In the construction environment, the fixture is known simply as the "Beaver". The principle of operation is the same as that of "Cricket". The punch, which carries out a rotational-translational movement, bends the material, rests on the matrix and cuts it off.

The Steel Beaver attachment for metal cutting is the same scissors that perform straight and curved cuts with the smallest radius of 1.2 cm. The removable accessory can be positioned as you like (it rotates 360 degrees) for ease of use.

If we compare it with the previously discussed equipment, "Bober" will cut a metal sheet of greater thickness - up to 1.8 mm. The advantages are exactly the same as those mentioned above.

The minimum rotational speed of the drill should be 1500 rpm, and the allowable stainless steel thickness is 1.2 mm.

It is worth noting that almost every nozzle works according to the same parameters. The only exception is the thickness of the metal workpiece, which one tool can cut and the other cannot. The result of the work will be a smooth, sharp edge without dents and other defects. This is inevitable if the nozzle for cutting sheet metal, copper, aluminum and other metal is selected in accordance with the speed of the screwdriver (drill).

If a novice user or an experienced builder does not have the desire and ability to spend money on an expensive cutting tool, he should take a closer look at inexpensive analogues. The cost of classic attachments - "Sverchka" and "Steel Beaver" - is 1800 and 2000 rubles, respectively (average market price). This fact also explains their relevance among repairmen and novice specialists.

The need for analogues of a grinder or other cutting equipment sometimes arises suddenly. Having nozzles at hand like "Cricket" and "Beaver" is a guarantee of a quick and safe solution to the problem.
