Universal scissors for metal - nozzle for a cricket drill. Types and applications of nozzles for a drill for cutting metal The difference between a drill and other tools

On this video useful attachment for a screwdriver or for an electric drill. The author recently purchased this cutting tool sheet metal, tinplate, corrugated iron. The device is compact, weighs only 400 grams, easy to use. You can buy it from this Chinese store.
Equipment. In addition to the device itself, the key is included. Allen key on one side, 12 key on the other.

How does a screwdriver bit work?

The shank is screwed to the cartridge, the working part cuts the metal. The handle itself spins. And in the place where she was, there is another knife. By loosening the nuts, the blades can be rotated to any angle. They rotate around their own axis. The same nuts are fixed. The nozzle is very simple. The knives work due to the eccentric. Great for cutting sheet metal.
The video shows how a 1.5 mm thick metal sheet is cut.

This attachment is for cutting thin sheet profiled metal up to 0.8 millimeters thick. The set includes a replaceable matrix, a replaceable punch, a handle-holder. It has a low cost and is suitable for small amounts of work.
The device has two cutting surfaces. The handle must be installed before installation. When one plane is dull, unscrew the handle, turn the nozzle over, install it on the other side. We insert into the drill, fix it. You can start cutting metal.
As shown in the video, the cut is without deformation, the speed is decent.
There is a myth that the grinder cuts faster. Verification shows that this is not the case. The grinder is slightly inferior in speed to the nozzle on the drill.
The most important thing is that the cut is very even, smooth, without hooks. Cut grinder with burnt coating, burnt zinc. During cutting, there are many sparks that fall on paintwork on metal. If the sparks from the grinder fall on polymer coating, the surface for the next season may become rusty. Every self-respecting manufacturer categorically forbids cutting with a grinder. If the cutting technology is violated, it will void the warranty.
There are disadvantages when using the nozzle. You have to work with metal using both hands. On the roof, this is problematic. But on the other hand, she will perfectly cope with your roof and with the roof of a neighbor.

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

The tool performs a smooth cut even the most soft materials, which allows you to get any shape with neat edges.
After cutting, the workpiece does not need to be leveled and filed. You will be pleasantly surprised by the durability of these heads. It gives you maximum maneuverability.

If you have ever spent hours working with a hacksaw or the room is full of bad smell from the work of the grinder, then you will see the difference.
Working with metal with such a tool is safe. You can work with even the smallest details. It allows you to work freely while holding a drill in your hands when performing roofing, plumbing, bodywork, heating and ventilation work. Patented Cutter special form facilitates roofing and sheathing work without damaging the material profile.
If you are modifying a car according to the special requirements of the customer, you fit acoustic systems, perform plumbing, ventilation work, install kitchen sinks, make round or square holes, then you can no longer do without the help of a nozzle on a drill.

You can use it to cut out windows in a camper van or mobile home. It is easy to change the head punch, cutter. Depending on the goals, you can change the position of the head. There are four positions at your disposal. The tool rotates on a drill. Therefore, it is comfortable, regardless of whether you operate with your right or left hand. You have no idea how nice it is to work with him. The jigsaw cuts metal itself.

You don't even have to put in the effort. Just guide the tool or part. Cuts not only cleaner, faster and longer, but also easier. You get a lot more and pay a lot less. In the manufacture of this instrument, modern achievements of science and technology are applied. it's easy to do too.

Thanks to great choice With a variety of drill bits, this versatile tool can replace many other tools. For example, grinding discs eliminates the need to purchase grinder, and a nozzle for tightening screws and self-tapping screws will replace a screwdriver.

With these tools, you can do the following:

• grinding;
• polishing;
• cutting;
• mixing;
• twisting;
• drilling holes of different diameters;
• milling.

At correct use the result will be of the same quality as if the work was done with a special single-purpose tool. you can’t do without a drill with different nozzles for, a pigsty, cages for rabbits and others outbuildings in the country.

Types of nozzles

All nozzles for drills are divided by purpose:

• stops;
• for drilling holes, crowns;
• cutting, nozzle-scissors "Steel beaver" and "Cricket";
• for drilling at an angle;
• polishing and grinding;
• cutters for wood and metal;
• removable;
• sharpening.

The parallel stop is used to adjust the insertion depth of the drill, there are also special bottom drilling stands reliable fastening tool. In addition to the standard drilling function, blind holes can be made with a drill, for example, for installing hinges in wooden furniture. In this case, a Forstner drill is used. The base of the hole is flat, and its edges are absolutely smooth. Or they use feather drills instead.

Cutting attachments

Unlike a grinder, drill bits for cutting metals work more delicately and do not deform the coating of the material being processed. The tool is driven by the chuck of the tool on which it is installed.

For cutting metals, you should choose drill models with a speed of at least 2800 rpm.

Benefits of cutting attachments:

• even cut;
• comfortable work;
• easy to use and maintain, no adjustment required.

The nozzle on the drill "Cricket" is nibblers with two cutting heads. They are used for cutting thin sheet metal: profiled metal sheets, metal tiles, profiled or sheet plastic as well as polycarbonate. "Cricket" is simply irreplaceable when erecting on a site.

"Cricket" is used for sheets of materials with the following parameters:

• the thickness of sheet steel should not be more than 1.5 mm;
• stainless steel up to 1.2 mm;
• aluminum, copper and plastic no more than 2 mm.

The cut after processing this nozzle always remains smooth, without notches, and the coating is intact.

To make a high-quality and even internal cut, you must first drill a hole.

The nozzle matrix rotates, thanks to which it can work with both horizontal and vertical surfaces. The recommended number of revolutions of the tool to use this tool is 3000 rpm, the minimum is 1500 rpm.

Also, for cutting profiled sheet metal and tiles, the Steel Beaver scissor attachment is used.

The principle of operation is similar to the previous nozzle, the cut occurs due to the frequent reciprocating movements of the punch, which bends the material and breaks it against the matrix. This tool can make curved and straight cuts. The minimum cutting radius is 1.2 cm. You can work with it at any angle (360 °). Compared to the Cricket, the rig is capable of cutting steel sheet thicker - 1.8 mm. The main advantage of the nozzle is a smooth cut, and due to the absence of sparks, it does not deform during operation. protective covering material.

At the end of work, be careful with sheet material, since the cut edge becomes sharp after processing.

Attachments for grinding and polishing

With the help of nozzles on the drill for grinding and polishing, you can carry out the following types works:

• metal polishing, wood flooring, as well as glass surfaces;
• grinding of metal, details from it and other materials;
• removal of corrosion, scale, chipping and old coatings;
• glass edge grinding.

Compared to special tools these devices have a low price, and can cope with large quantity different tasks I make any surface perfectly even and smooth. In addition, they can be processed hard-to-reach places where other tools cannot be used. But due to not large sizes they are difficult to fulfill large volume work.

When purchasing a nozzle for a drill for processing wood or other material, you should carefully study the instructions. Since for different types rigging required different power and the number of revolutions of the tool.

All polishing and grinding attachments are a rod on which grinding material is fixed, such as foam rubber, felt, brushes or sandpaper.

The following types are produced:

• plate;
• disk;
• fan;
• drum;
• end;
• cup.

Polishing devices are divided not only by the type of construction, but also by the degree of hardness: hard, soft, super soft, embossed.

Cup

A cup attachment for a drill for grinding wood or other coatings consists of a rod for fixing in a cartridge, and a cup-shaped body filled with hard or light bristles. Most often it is used to remove corrosion or old coatings. Models with a soft polishing part are also available: foam rubber, felt or other similar material. The body is made of durable and lightweight plastic or metal. Soft nozzles on a drill are most often used for car polishing.

Disc and platter

Disc devices, like cup ones, consist of a rod, a body and a grinding material. The main difference from the previous model is the direction of the bristles (steel wire, brass brush), it is directed from the center to the edges of the disc. You need to use them carefully, as you can quickly ruin the coating.

Plate attachments for polishing or grinding drills are made according to the same principle as for grinding devices. But instead of a thread, they are equipped with a movable or fixed rod for fixing in the cartridge. Sandpaper is attached to them with Velcro.

Experts recommend purchasing plate nozzles with a moving rod, rubber or with a soft and thick layer between Velcro and the base. Since then you can adjust the angle of the drill and smoothly follow the contours of the material.

When working with a rigid cymbal, it is more difficult to control, and even with a slight tilt, it will make a noticeable indentation in the surface. As a result, you can completely spoil the material. Therefore, they are recommended to be used only with a firmly fixed instrument on the stand.

Fan (petal), drum and end

Grinding fan nozzles on a drill are small disc in the center, to the edges of which the petals of sandpaper or other abrasive material are fixed. It is convenient to handle hard-to-reach places, internal cavities or grind holes with such a device, as it is able to take any shape. They are fixed in the drill chuck in the same way as previous models, using a rod.

Drum made in the form of a cylinder with a rod, covered on the outside sandpaper. Unlike a poppet attachment on a drill, the processing surface is parallel to the chuck, and not perpendicular. They process wood, metal, glass. Most often used for sharpening the end of glass. They are soft and hard, depending on the purpose of the appointment.

The end ones are a rod, at the end of which the processing material is fixed in the form of a circle or cone. Nozzles work on the principle of a file. Using them, you can increase the diameter of the hole, as well as remove notches and make the edges smooth.

Other nozzles

An angled drill attachment allows you to make holes in places where it is impossible to work normally. The angle can be adjusted or be fixed - 90 °. Drill bits are used for drilling in wood, concrete, ceramic and tiles, metal and other materials of large holes. They are made of high quality steel so that the holes are smooth, without chips and cracks.

The nozzle for sharpening drills is a body with a leash and grindstone inside. Sharpening holes are different diameters. Their number can reach 15 pieces. Mixer attachments are used for mixing various mortars, paints and other mixtures. Selected depending on the consistency. There is also a special nozzle for tightening self-tapping screws or screws, but it should be purchased for drills equipped with a speed reduction function.

For bird owners, a pen-removable attachment for a drill for plucking birds has been developed. It instantly and safely removes all feathers from the carcass. In this case, the skin and meat are not damaged. Before work, it is not necessary to pre-scald the carcass or process it after plucking with a blowtorch.

The nozzle on the drill for plucking birds is easy to use, you just need to fasten the tool with high quality and bring the bird to it. It is made from easily washed materials and takes up very little space.

For those who work with wood material, nozzles cutters of different types are issued. They allow you to make grooves various forms, machine holes or remove defects. They are pointed and backed.

Before working with any nozzles, you should check the reliability of their fastening in the chuck and the material being processed. The drill must be held with both hands. Be sure to use protective equipment (gloves, goggles) while working.

Homemade nozzles for a drill - video

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 are 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 alternative way process the material, but also in the case when heating sheet metal unwanted.

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 expendable materials.
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 battery, can be performed in places where it is not possible to connect to the 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 universal fixture, 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 subjected to constant loads not deformed. 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. 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. High quality 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.

The need to cut products made of metal arises in many situations related to construction and repair work. To fulfill this technological operation special equipment is used various types, but if it is not at hand, a drill attachment for cutting metal can help. Using such nozzles and a hand-held electric drill, it is possible to perform effective cutting of products of small thickness made of various metals.

Types of metal cutting equipment

You can cut a metal sheet or a more massive metal product using various equipment.

This device is also known as the "Bulgarian". It can be used to cut rebar, plate metal and other types of metal products. This is the most popular equipment used for such purposes.

Such a saw allows you to make cuts at different angles and perform them with great accuracy. Meanwhile, when using this equipment, the resulting cuts have a limited depth and a large amount of waste is generated.

This is a high-performance metal cutting equipment, with the help of which workpieces of a simple configuration are processed.

Such equipment allows you to perform cuts at different angles. Like a jigsaw, and band saw because of their design features impose significant restrictions on the size of products that must be cut.

Equipment of this type is innovative. It allows you to cut metal with high precision, while the thickness of the workpiece can reach up to 20–30 cm. The most significant disadvantage of this cutting method, in which the workpiece is not subjected to thermal action, is the high cost.

As mentioned above, you can also use drill bits for cutting metal products, which are on modern market presented in a wide variety.

Features of the use of nozzles on a drill

Nozzles, with the help of which an ordinary electric drill turns into a device for cutting metal, in fact, are a punch (cotter pin). Making numerous reciprocating movements in the internal cavity of the matrix, such a punch pierces a metal sheet, forming a cut line on it, the width of which is 3.1 mm. When using nozzles, a point effect is exerted on the treatment area, due to which the protective layers on the surface metal product fully retain all their functions.

With the help of a drill attachment, you can cut metal sheets of the following thickness:

• made of aluminum - up to two millimeters;
• made of copper, brass, sheet iron, zinc and galvanized steel - up to one and a half millimeters;
• made of stainless steel - up to eight tenths of a millimeter.

The reciprocating movement of the punch, which is the main working body of the nozzle, is reported due to the rotation of the chuck of an electric drill. It should be borne in mind that such a nozzle can effectively cut a metal sheet only if it is used in conjunction with electric drill, the cartridge of which rotates at a frequency of at least 2700 rpm.

Benefits of using drill bits

Drill nozzles, when compared with such a popular metal cutting tool as a grinder, have a number of advantages.

1. The cut is of high quality.
2. When using a drill attachment for cutting metal, there is no need to purchase additional consumables, which significantly saves money.
3. The use of such a nozzle provides high performance cutting process.
4. Drill bits are highly versatile.
5. Due to the fact that this tool is equipped with a special handle, the cutting process with its help is very convenient.
6. These attachments are suitable for both electric and pneumatic drills.
7. The convenience of these nozzles is undeniable both in use and in maintenance.
8. With the help of such tools, cuts of almost any configuration can be made.

Despite the simplicity of the design of such nozzles, their use requires certain skills and dexterity from the user.

Popular models and their applications

Modern models drill attachments allow you to cut sheet metal not only in a straight line. With this convenient and easy-to-use device, you can also perform curly cuts which is often required during installation roof structures, ventilation ducts, as well as gutters and other elements of the drainage system.

Using such nozzles on a drill, cuts can be made in almost any spatial position. An equally important advantage of these nozzles is that they do not require pre-configuration.

Among the most popular models nozzles for drills for cutting metal, presented on the domestic market, are the following:

• "Cricket" (from the company "Enkor");
• Sparky NP 1.8L;
• EDMA NIBBLEX;
• ACCO YT-160A.

The differences between the models of nozzles for drills are not in the principle of their work, but in maximum thickness cut metal and a number of other specifications. Modern models of nozzles for drills allow you to get even and neat cuts with sharp, even and uncluttered edges. At the same time, the protective coating applied to the surface of the metal sheet is not damaged and fully retains all its functions.

"Cricket"

One of the popular attachments for a drill, which is a compact nibbling (cutting) scissors, is a device called the Cricket. This nozzle, which allows you to get a smooth and accurate cut, can be used for cutting both flat and profiled metal sheets.

Nozzle-scissors "Cricket" is designed to operate from a pneumatic or electric drill (screwdriver) with a power of at least 420 W

With the help of the “Cricket” scissors attachment, you can cut not only a metal sheet, but thin-sheet products made of polycarbonate and other polymer materials. The thickness of products that can be cut with this compact nibbler can be up to:

• 1.5 mm - for steel sheet material;
• 1.2 mm - for stainless steel;
• 2 mm - for copper and aluminum, as well as polymeric materials.

With the help of the attachment for the Cricket drill, it is possible to cut sheet material in horizontal and vertical planes, as well as to perform internal cuts on the surface of the sheet.

It should be borne in mind that in the place of the sheet from where the internal cut will be made, it is necessary to pre-drill a hole.

"Cricket" is good nozzle on a drill for cutting metal tiles and corrugated board. When using this device for cutting metal, the surface of these materials is not deformed, and the cut itself is smooth and accurate. The Cricket nozzle can easily cope with such challenging tasks, as artistic cutting and the creation of large-diameter holes in sheet material.

"Steel Beaver"

Another popular drill attachment that can be used to cut metal is the Steel Beaver. The principle by which such nozzles work on a drill is similar to how punching scissors function. When using this device, sparks are not formed in the cutting zone and there is no thermal effect on the metal sheet, respectively, the protective coating that is applied to it is not burned.

Not always found in foliage finishing material required size and forms. During repair, installation of a fence made of profiled metal sheet, device roofing it is required to quickly cut this or that workpiece, adjust the standard element to the actual dimensions. For cutting, you can use an angle grinder, scissors, other cutting tool. If it is not at hand or you are limited in funds, then there is an alternative - a cricket drill attachment.

Short description

This is a removable mechanism that is mounted on a standard electric hand drill chuck. It is designed for cutting flat and corrugated metal sheets:

• Composite aluminum sheet up to 2 mm thick
• Galvanized profiled sheet up to 0.8 mm thick
• Copper, brass up to 1.5 mm thick

By appearance the nozzle on the drill cricket resembles a steel blank cylindrical shape, with "fingers" sticking out in both directions. A cylindrical blank is a body through which torque is transmitted from a drill to two cutting surfaces. "Fingers" are paired matrices that are in direct contact with the metal workpiece. The tool comes with a plastic threaded handle-holder, which is screwed onto one of the paired cutting surfaces.

In addition, a spare die and punch, as well as a hex wrench, are supplied with the nozzle.

Principle of operation

The cricket drill attachment does not cut metal like an angle grinder, but cuts it due to the frequent translational movements of the matrix. The working unit converts the torque from the drill rotor. The tool cannot run at low speeds. To obtain a quality cut, it must maintain a rotation speed of 2700-3000 rpm. If this parameter is not met, then the metal around the cut bends, the quality of the finished product deteriorates.

Application area

The nozzle is widely used for cutting thin sheet metal. Its design is specially designed to perform both straight and curved cuts. With a certain work skill, you can perform figured sawing along a complex path.

Unlike the corner grinder or shears for metal, the “cricket” is able to cut from the center of the workpiece without creating through cuts.

The cutting attachment is especially in demand for roofing works and installation of fences. It's all about the material. A profiled sheet is mainly used, which is perfectly cut with this tool.

Positive properties

The cricket drill attachment is widespread due to a number of positive properties. She wins on her own performance characteristics some power tools.

• Mobility. She has small size, much less than that of the grinder. The nozzle is easy to install and remove from the drill, which facilitates the work
• High autonomy. The "cricket" has two full-fledged cutting dies. If one fails, you can use the other. In addition, a third spare is included with the tool.
• Maintainability. There are no complex mechanisms in its design, there is practically nothing to break. The cutting part is supplied ready block which is easily installed on site
• Work speed. Numerous tests show that the cutting performance and sawing speed of the attachment is far superior to that of an angle grinder. Metal shears don't compare at all
• Cutting quality. According to this indicator, the "dragonfly" has no competitors. Due to the translational movements of the matrix, the edge of the metal in the area of ​​​​the cut remains flat. It has no burrs. The metal does not heat up, the protective polymer coating of the profiled sheet does not burn. Zinc protection is not destroyed. While in the process of sawing with a grinder, the edges of the sheet are charred, burrs remain on them
• No collateral damage. Working with a grinder is associated with the formation of sparks that scatter over a considerable distance. If a galvanized profiled sheet is processed, then sparks burn out the protective coating. During operation, the metal will be covered with brown dots of rust. Sawing with a dragonfly nozzle takes place in the complete absence of sparks. No rust issues
• Ergonomics. Handle - holder makes working with the tool convenient and safe

Negative properties

There are not so many of them, they do not have a critical impact on the choice of tool:

• Grip type limitation. He only has two hands. Therefore, it is impossible to carry out operations on inclined planes, where it is necessary to keep
• metal thickness. Attachment designed for cutting thin metal

Rules for safe work

Practically do not differ from standard measures when working with a saw tool:

1. Do not cut while holding the tool with one hand. This may cause it to rebound;
2. Before starting work, the rigidity of the fastening of the handle-holder is checked. To do this, it rotates clockwise until it fails.
3. It is allowed to work only in protective glasses and gloves;
4. It is recommended to cut the sheet away from you, and not towards you;
5. It is forbidden to work with a defective tool. These include: a loose drill chuck, a worn sawing die, a loose handle holder

Firms - manufacturers

Products of different brands are similar to each other. The main difference is in the thickness of the sheet that a particular model can cut. The price directly depends on this.

There are several noteworthy companies on the Russian market:

• Encore
• Corvette
• Sparky

The use of scissor attachments for a drill greatly facilitates roofing, installation of a metal fence, and other manipulations with sheet material. Convenient combination with hand drill reduces the cost of purchasing expensive specialized tool. The finished product is neat and high quality.
