Steel beaver attachment

The device is designed for cutting flat and profiled sheets (corrugated board, metal tiles). It has a cutting mechanism that works similar to the processing of materials with a nibbler.

In the process of metal processing using the “Steel Beaver” tool, sparks are not formed and the protective layer of the metal coating is not burned.

  • cutting is performed at a drill rotation speed of 1500–3 thousand rpm;
  • the maximum thickness of aluminum and copper sheets should be 2 mm;
  • stainless steel sheets must be no more than 1.2 mm thick;
  • the maximum thickness of the steel sheet can be up to 1.8 mm;
  • changing the direction and angle of the cut. 360 degrees;
  • minimum cutting radius. 12 mm.

Special nozzle “Cricket” for a drill for cutting metal

Cricket nozzle. The Cricket device is a nibbler that is capable of making a straight cut. The tool is used to cut not only smooth, but also profiled metal sheets.

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

Cutting metal with a Circular Saw: Toolsday with Metal Saws

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

Using the Cricket nozzle, 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 processing of metal tiles or corrugated board is required. After using Cricket, the materials used will not be deformed, and the cut will turn out to be smooth and beautiful.

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

What are metal cutting attachments

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

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

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

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

The cutting tool is driven by the drill chuck, on which it is fixed. It is worth noting that the nozzle will be able to cut metal only if the number of revolutions of the drill is at least 2700 rpm.

Types and application of drill bits for metal cutting

Engaged in construction or repair work, almost everyone is faced with the need to cut any workpiece made of metal. To perform this procedure, you can use an angle grinder, cutter, hand scissors for metal.

Advantages of attachments

Compared to an angle grinder, the drill bit has many advantages.

  • High cut quality.
  • Cost savings due to the fact that you do not need to spend money on consumables.
  • Performance.
  • Versatility.
  • Convenient cutting process, as the tool is equipped with a special handle.
  • Possibility to work from an electric or pneumatic drill.
  • Easy to use and maintain.
  • Possibility to make holes of any shape.

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

Drill bit models and their application

With special attachments on the drill, you can make both straight and curved cuts. Make curly cuts for installing gutters of the gutter system or ventilation parts of the roof, cut in the vertical and horizontal direction.

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

On the construction market, drill bits are presented in several models:

  • ACKO YT-160A.
  • EDMA NIBBLEX.
  • Sparky NP 1,8 L.
  • “Cricket” from the producers of Enkor.

By and large, all models of drill bits work according to the same parameters. An exception may be the thickness of the metal sheet, which can be cut by this or that tool.

After using the tools, the edge is sharp, even and not wrinkled. It is only necessary to make sure that the rotations of the used drill correspond to 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 craftsmen, this tool will be the 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.

How to choose and use electric screwdriver bits for cutting metal?

Using a special attachment, the electric screwdriver can be modified into a tool for cutting metal products. It is quite convenient, high quality and economical. This method is a very effective alternative to special metal cutting tools. However, in order for the result after working with an electric screwdriver with such a nozzle to really be of excellent quality, you need to choose the right nozzles.

How to choose

  • Don’t ignore the domestically produced tips. In terms of quality, they are not at all inferior to foreign products, and at a price they can be much more profitable.
  • Do not buy attachments by hand. The marriage may not be noticeable at first glance, but in the future, its presence may result in a serious problem.
  • Make sure that the mechanism is suitable in all parameters for your particular instrument.

When choosing a milling cutter for working with an electric metal screwdriver, you should also take into account the purpose of the mechanism and choose a product that matches the specifics of the work. You can divide nozzles into the following types:

  • device for cutting thin sheet metal;
  • a sharpening product for regenerating a cutting metal edge;
  • attachment for polishing, grinding metal coating.

The main difference between electric screwdriver bits is the thickness of the metal being cut. Other technical properties are also important. Modern building sales departments, as well as Internet sites, offer many models of metal cutting attachments, thanks to which the tool produces smooth and neat cuts. For example, the following attachments are the most common models:

  • “Cricket”.
  • “Steel beaver”.
  • Sparky NP 1,8L.
  • EDMA NIBBLEX.
  • ACKO YT-160A.

Particular attention should be paid to the HPM “Cricket” attachment using the example of the “Enkor 14210” model. The fixture can be used for metal sheets up to 1.6 mm thick. If it is copper, aluminum or polymer material, then the mechanism will also take a 2 mm blade. The product is put into operation by a cartridge. With the help of these products, it is possible to make any kind of cuts. The strength of the attachment is given by the tool steel, which is used in the manufacture, due to this, the device has a long service life. Also, the advantages of the model include low noise and mechanical losses. It is quite suitable for artistic cutting and making large-diameter holes on metal.

The Steel Beaver attachment is also worth mentioning. It is a kind of steel scissors. The model is more suitable for metal tiles and corrugated board. The advantage of the nozzle is its property not to burn the protective layer of the metal product, due to which the coating retains its anti-corrosion qualities. The fixture is used for steel (up to 1.8 mm), stainless steel (1.2 mm), copper and aluminum (2 mm). Minimum cutting radius. 12 mm.

The Sparky NP 1,8L device allows you to make both linear and radial cuts. Differs in high quality edging. Perfect for metal tiles.

Features of the

When asked whether it is possible to drill metal with an electric screwdriver, professionals give a positive answer. However, it is worth knowing that cutting for metal with an electric screwdriver is possible only at home and when working with an insignificant volume. For example, it is easier to bring multiple attachments to a proposed project than one heavy power tool. For professional work in industrial processing of metal sheets of large thickness, attachments for an electric screwdriver will not replace a specialized tool such as an angle grinder.

A device that turns an electric screwdriver into a metal-cutting device is essentially a punch. It evenly penetrates the metal sheet by means of multiple reciprocating movements. In the course of work, the tool acts on the sheet in a point, due to which the coating retains the maximum performance.

Thanks to a special attachment, the master can work with thin metal and sheet metal with a width of no more than 2 mm. The product consists of two cutting parts, one of which is covered with a handle. If the blade is dull, then the handle can be adapted to it, and the work can be continued with the sharp part. According to some craftsmen, this method is even faster than, for example, when working with an angle grinder. The cut edges are not deformed, the convenience is created by the absence of sparks when cutting.

Advantages and disadvantages

Cutting metal with an electric screwdriver has many advantages.

  • The result of working with an electric screwdriver is a high-quality and even cut.
  • Profitability. When purchasing a nozzle, there is no need to make a purchase of additional consumables.
  • Greater device performance.
  • The versatility of such attachments.
  • Due to the presence of a special handle, the workflow is light, convenient, and efficient.
  • Some models are applicable to any screwdriver and drill, electric or pneumatic.
  • Special attachments are quite easy to maintain.
  • This method makes it possible to carry out cuts in almost any configuration.

The disadvantages of this method of cutting metal include some inconvenience in work for novice craftsmen. First you need to adapt to the process, acquire some skill, even art. Experienced craftsmen will not need this. they will easily cope with the task. Another disadvantage of the product is the difficulty when working on the roof, since both hands are used when cutting metal.

Recommendations for use

Turning to a screwdriver as a tool for cutting metal, it is worth considering some of the features of working with it. When using this method for the first time, heed the recommendations of experts.

  • Before work, make several cuts on unnecessary metal blades in order to adapt and adapt to cutting and avoid mistakes during the main work.
  • Hold the drill or electric screwdriver with both hands to ensure a clean and smooth cut of the desired shape.
  • Make sure that nozzles and cutters are stored in dry rooms where there are no conditions for metal oxidation.

For how to use the sheet metal cutter, see the following video.

Other useful drill bits

The next group of attachments for an electric drill is designed to help its owner when performing a large volume of the same type of work.

1.Nozzle for installing aluminum rivets.

There are many different designs of them, both for one size of rivets and with replaceable sleeves for different diameters. Such a nozzle will be very useful if such fasteners have to be done often:

And the point here is not only in the automation of manual labor, but also in the speed of this type of work.

Tape nozzle for self-tapping screws.

It is even more than the previous one, it allows you to save time when installing plasterboard partitions or large volumes of fastening other sheet materials using self-tapping screws.

attachment, cutting, metal

Sanding belt attachment.

Such a nozzle costs several times less than a manual belt sander, and the work with it can be done the same, which practically neutralizes some difference in convenience in work.

A drill attachment will be useful, allowing you to turn it into a hammer drill. We have already written that an impact drill (link to article), due to the specifics of the formation of a micro-impact, cannot perform the work of a puncher, and even more so to receive a blow without rotation. The same nozzle is nothing more than an impact unit of a hammer drill, which makes it one of the most needed in the household for an electric drill.

Just to use it in full, it is worth purchasing a cartridge for securing the corresponding tool.

The pruning shear attachment is useful for cutting thick power cables as well as for trimming fairly thick tree branches.

If you want to save money on the purchase of a jigsaw, and work for it is periodically found, then the corresponding nozzle will help turn your drill into it.

Accessories for adapting an electric drill to a hand-held circular saw can also be useful to you on the farm.

attachment, cutting, metal

Not to mention such small but useful attachments, such as a nozzle for sharpening small-diameter drills, a pump nozzle for pumping small volumes of liquid or a nozzle for polishing various surfaces.

It is clear that instead of a polishing nozzle, you can insert various cleaning, grinding and other nozzles into the drill, which we will not write about in this article due to their wide popularity and applicability. As well as about the various types and types of drills and drills directly used to work with a drill.

Of course, there are more exotic drill bits:

But the most commonly used attachments for electric drills are assembled in a short

Dear readers, if you have any questions, ask them using the form below. We will be glad to communicate with you

Many experienced craftsmen know that purchasing a quality screwdriver or electric drill is much more profitable than buying a tool of dubious quality. Usually, manufacturers provide for the possibility of successful use of various attachments on it, which completely change the working functionality. In particular, jigsaw attachments. Whether they are effective, we will consider further.

Cutting

The drill attachment for cutting wood is a rather complex mechanism that works on the principle of a jigsaw. It can be used to cut wood up to 20 mm thick, as well as plywood and chipboard.

It can also be used to cut plastic and even steel. Thus, this device will be useful to every home craftsman, unless, of course, there are no special tools for cutting this or that material.

True, it should be noted that the price of such a nozzle is quite high, which is explained by the complexity of its mechanism.

Advice! Before making an internal cut with a jigsaw, it is necessary to drill a hole equal in diameter to the width of the saw.

Drill attachment for cutting wood saw

The main purpose of a drill when working with wood is to drill holes. However, this tool is much more powerful than most people think. To expand its functionality, special wood nozzles are used, which, in fact, this article is devoted to.

Next, we will look at what drill bits for woodworking exist, and for what purposes they are used.

Making large holes

To make holes of large diameter, several types of nozzles are used:

  • Pen drills. due to their flat cutting edge and special sharpening, they allow you to make holes in wood, chipboard, plywood and OSB up to 60 mm in diameter. It should be noted that pen drills are not only for wood, but also for metal.
  • Drill bit for wood. allows you to drill holes in wood with a diameter of up to 100 mm.
  • Forstner drill. has a centering point. With this drill, you can make blind holes, for example, for mounting hinges in the manufacture of furniture.

Advice! When making a hole in chipboard and other similar materials, do not press down hard on the drill, as this can lead to chips and cracks.

I must say that there are special devices on sale that allow you to change the drilling angle. Their purpose is to provide ease of drilling in hard-to-reach places.

Cylindrical router bit for wood drill

Angle stops and milling attachments for a drill

Most of these attachments turn an electric drill into a kind of hand router. With their help, you can mill various grooves, make grooves, cut tiles and much more.

An interesting way to independently make a simple milling nozzle for a drill, offered in the video:

True, for those who want to make such a nozzle for themselves with their own hands, we would advise to slightly modify the design, namely:

  • Make the distance of the thrust platform in relation to the drill adjustable by making the fastening of the plates to the ring movable. You can make longitudinal grooves in them, and screw them to the ring with 4 screws, or come up with another rather rigid, but adjustable mount. This will make it possible to perform deeper milling.
  • It will be useful to provide for the possibility of attaching a parallel stop to the thrust platform, which will allow milling at a given distance from the base edge of the workpiece.

Jigsaw attachment for drill

For the successful execution of work on the figured cutting of a tree, it is necessary to fulfill a number of prerequisites:

  • The electric drill must be installed on a sturdy frame or equipped with a lockable stop.
  • The drill drive must have the necessary power reserve, because the energy during reciprocating movement is always more than with rotary.
  • A too high-speed drill will force the gearbox to be loaded, since with a large number of strokes of the saw blade, it quickly heats up and breaks down.
  • Woodworking is accompanied by the appearance of a significant amount of small chips, from which it is necessary to protect the drive.

It should also be remembered that any electric drill is not designed for long-term operation, so the performance will not be high.

The main design difference of the jigsaw attachment is the length of the saw blade: it is always longer, due to the presence of the acceleration phase of the blade by the transforming mechanism. Such a jigsaw attachment includes:

  • body;
  • a mechanism that converts the rotational movement of the shaft into the translational movement of the saw blade;
  • adjustable limiters;
  • control system.

Usually, jigsaw attachments for a drill have a useful saw length of up to 100 mm, and are designed to work with a drill with a power of at least 750 W (and, if necessary, cut aluminum. at least 1000 W). The number of revolutions of the main tool is taken in the range of 2500 2700 rpm. The cutting length in this case is always limited, and for internal cuts at the starting point of the workpiece, an inlet hole with a diameter slightly larger than the width of the saw blade is drilled.

The disadvantage of the nozzle is its low rigidity due to the fact that most of the knot hangs in the air without reliable support. Accordingly, the bending moment at the opposite end of the saw blade is quite high.

Milling

With special tips, the drill can even be used for milling wood parts.

Reception of cutters (cutters) are of various types:

  • Cylindrical;
  • End;
  • End;
  • Disk;
  • Shaped, etc.

The choice of cutter depends on the type of operation being performed. For example, if it is necessary to make grooves in the part, use disc cutters for wood for a drill. For complex cuts, it is best to use a router bit.

It should also be noted that cutters differ in the shape of the teeth, which are:

  • Pointed;
  • Backed up.

Refined teeth are good because they can be re-sharpened if necessary, while sharp-pointed teeth are not restored.

Screwing in self-tapping screws

Self-tapping attachment is the simplest type of tip. However, it should be noted that it can only be used with those types of drills that have the option to reduce the speed.

These products, as a rule, are sold in sets, in which there are heads of several diameters. This allows you to work with self-tapping screws and screws of different sizes.

These are, perhaps, all the most common types of attachments. I must say that there are also less popular tips, for example, flexible cable drills that allow you to make holes in hard-to-reach places, as well as angle bits that allow you to turn a drill into an angle grinder. True, on sale they can be found much less often.

  • metal roofing;
  • corrugated board;
  • sheets with profile stamping and stiffening sheets;
  • large volumes of smooth steel.

When making a cut, the nozzle does not damage the edges of the protected metal, but rolls, thanks to which the material is protected from corrosion. Work can be carried out horizontally and vertically.

The advantage of the “cricket” is its high productivity. 1 m / min. although the angle grinder works faster, it damages the protective and decorative coating that is used for metal tiles.

You can cut with a drill with such an accessory even sheets with a complex relief, since it is convenient to move the cutter in the desired direction. Craftsmen pay attention to the device and due to its low cost. So, the domestic “cricket” is several times cheaper than professional die-cut electric shears.

The tool also has a drawback. Even with a virtuoso mastery of a drill with a nozzle, it is difficult to achieve an even cut. However, this is not critical. The fact is that usually the seams are covered with special shaped parts.

Instructions for using the “Cricket” nozzle

  • following the surface relief, bending around the edges. for an average bend radius;
  • when processing metal tiles. along the stiffeners.

Why a drill is more convenient than other metal cutting tools?

A drill is a tool that every craftsman has in his arsenal. However, it is rarely used for cutting metal. But the attachments, the variations of which are becoming more and more, make it possible to use the tool for these purposes as well.

The drill has many advantages over the other tools in question. In particular, it is ease of use, accessibility, versatility. Rechargeable models are available. You can work with them when the power grid is not available.

Nozzles are devices that are punch in design. The metal rod, due to the reciprocating movement inside the matrix, punches the sheet. The method is especially convenient when working with materials coated with protective compounds: due to a point effect, the top layer is rarely damaged.

The upper cutting part of the nozzle moves up and down, thus cutting the metal and pushing its particles into the slot

The maximum sheet thickness that can be cut with this tool depends on the type of metal.

13 Ways to Cut Metal

“Steel beaver” (die-cut nozzle)

This is a classic nozzle that is used for flat sheets and metal roofing tiles. The assembly consists of a shaft that turns freely in a bearing. The principle of operation resembles a crank mechanism. But in this device, energy is spent on rotation.

The ready-to-use “steel beaver” contains a support section attached to the bed. The movable part performs reciprocating movements during operation. The drill moves relative to the nozzle due to the occurrence of reactive torque.

The “steel beaver” is used mainly for flat products or profiled sheets with a significant bend radius. This tool allows you to control the cutting line well. The protective decorative coating, which is often used to cover the metal, does not melt, sparks are not formed, the edge remains free of burrs. However, the zinc layer is burned. the cutting line can be as long as the operator needs.

Attention! If there is a need to cut a sheet with small-diameter bends, it is recommended to use the “Cricket” nozzle model.

Master Class. How to make a lathe from a drill

Surprisingly, a drill can also be used to create a simple lathe. All structural elements are made by hand (with the exception of screws and bearings). There is nothing superfluous. only the most necessary!

The first step is to prepare everything that is required for work.

Next, you should decide on what the dimensions of the countertop will be. It is not necessary to take the dimensions given in the example. you can have your own.

On a note! The dimensions of the table top depend on what the dimensions of the drill are and the dimensions of the workpieces to be processed.

After that, the center of the drill is determined. It is placed on the countertop, then the distance from it (countertop) to the center of the chuck is measured. A square piece of wood is taken, a hole is made in it for the neck of the drill. The center of this hole will be the previously measured distance. This will fix the drill exactly.

All unnecessary is cut off, after which the mount must be put aside for a while.

We start assembling two corner pieces, which are a pair of rectangular pieces of wood glued to each other.

The smaller part (headstock) will hold the rotating workpiece from the opposite side, and the larger one is the bed, the tool itself will rest on it. It is important that the height of the headstock is about 1.5 times greater.

Then, guides are created on both blanks. holes are drilled along the mowing line, which are then connected at an angle.

3 important elements are ready. Spray them if you like.

A hole for the bearing is drilled in the headstock (it should not be through). A bolt is inserted into the bearing itself, pulled together with a nut. Glue is applied to the seat, then the bearing is placed (it should be nut outward).

The slats are attached to the worktop. Holes are drilled (3 pieces) for long bolts, the drill mount is fixed with self-tapping screws. You also need to install a small wooden rectangle under the handle of the drill. All parts are screwed.

The drill itself is fixed with self-tapping screws. it must “sit” rigidly.

The design is almost ready, all that remains is to make a clamp to hold the workpiece. For this purpose, a round is cut out, self-tapping screws are inserted into it, as well as a bolt with a nut.

The finished part is fixed in the chuck.

Mechanical cutting methods

The mechanical method is also called cold, since the material is not exposed to high temperatures. The work uses tools, the strength and hardness of which is higher than that of metal.

    A circular saw. The tool allows you to cut metal at different angles, and with a fairly high accuracy. The disadvantage of a circular saw is a shallow cutting depth and a large amount of waste.

Circular saw for cutting metal

  • Hand scissors. It is a simple device that is relatively inexpensive but requires significant physical effort.
  • angle grinder, or angle grinder. Convenient for cutting rebar, plate, and other similar products.
  • READ  Metal Cutting With A Hacksaw For Metal

    Many craftsmen use an angle grinder to cut sheet metal.

  • Machine with a band cutter. The machine processes metal at different angles. However, due to structural features, the size of the sheets is extremely limited.
  • Guillotine. Such devices are characterized by high performance. However, they are used only to obtain simple blanks.
  • Guillotine (locksmith tool)

  • Hydraulic equipment. This is a new word in metal processing technology. Such equipment provides high cutting accuracy, and the thickness of the workpiece can reach 20 cm or more. Not every master can afford expensive equipment.
  • The foliage is cut mechanically and thermally. And in the arsenal of craftsmen, a nozzle for a drill for cutting metal appears more and more often. Each of them has advantages and disadvantages. Some types of equipment are used in factories or in private workshops, others are in demand in home workshops.

    Benefits of using drill bits

    Drill bits, when compared to such a popular metal cutting tool as an angle grinder, have a number of advantages.

    • The cut is of high quality.
    • When using a drill bit for cutting metal, there is no need to purchase additional consumables, which significantly saves money.
    • The use of such a nozzle ensures high productivity of the cutting process.
    • Drill bits are highly versatile.
    • Due to the fact that this tool is equipped with a special handle, it is very convenient to perform the cutting process with it.
    • These attachments are suitable for both electric and pneumatic drills.
    • Undeniable convenience of these attachments both in use and maintenance.
    • With the help of such tools, you can make cuts in almost any configuration.

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

    Popular models and their areas of application

    Modern models of drill bits allow cutting sheet metal not only along a straight mowing line. With the help of such a convenient and easy-to-use device, you can also make curly cuts, which is often required when installing roof structures, ventilation ducts, as well as gutters and other elements of the drainage system.

    Using such drill bits, cuts can be made in almost any spatial position. An equally important advantage of these attachments is that they do not require preliminary adjustment.

    This attachment turns the drill into an electric shear that works on the principle of cutting, not nibbling.

    Among the most popular models of drill bits for metal cutting on the domestic market are the following:

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

    Cutting shears-attachment on the EDMA NIBBLEX electric drill for cutting metal and plastic

    The differences between the models of drill bits are not in the principle of their operation, but in the maximum thickness of the cut metal and a number of other technical characteristics. Modern models of drill bits allow you to get straight and neat cuts with sharp, even and unnoticed 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.

    Features of the use of drill bits

    The attachments, with the help of which an ordinary electric drill turns into a device for cutting metal, are, in fact, a punch (cotter pin). Making numerous reciprocating movements in the inner cavity of the matrix, such a punch penetrates 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 processing area, due to which the protective layers on the surface of the metal product fully retain all their functions.

    Using the drill bit, you can cut metal sheets of the following thicknesses:

    • 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 communicated by rotating 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 an electric drill, the chuck of which rotates at a frequency of at least 2700 rpm.

    Examples of cuts with a nozzle of galvanized sheet (0.55 mm) and aluminum (2 mm)

    Drill bits for cutting metal: types, features, application

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

    Figured cutting of metal with a punching nozzle for a drill

    “Cricket”

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

    Scissor attachment “Cricket” is designed to operate from a pneumatic or electric drill (electric screwdriver) with a power of at least 420 W

    With the help of the “Cricket” scissor attachment, you can cut not only a metal sheet, but also thin sheet products made of polycarbonate and other polymeric materials. In this case, the thickness of the products, for which these compact nibbling shears can be used, 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 “Cricket” drill attachment, you can cut sheet material in the horizontal and vertical planes, as well as make internal cuts on the sheet surface.

    “Sverchok” works on the principle of nibbling scissors

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

    “Sverchok” is a good drill attachment for cutting metal tiles and corrugated board. When using this device for cutting metal, the surface of these materials does not deform, and the cut itself is smooth and accurate. The “Cricket” nozzle can easily cope with such complex tasks as artistic cutting and creating a large-diameter hole in sheet material.

    Types of equipment for metal cutting

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

    This device is also known as an “angle grinder”. It can be used to cut rebar, plate and other types of metal. This is the most popular equipment used for this purpose.

    This 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 equipment for metal cutting, with the help of which the processing of workpieces of a simple configuration is carried out.

    This equipment allows you to make cuts at different angles. Both the jigsaw and the band saw, due to their design features, impose significant restrictions on the size of the products that need to be cut.

    This type of equipment is innovative. It allows you to cut metal with high accuracy, while the thickness of the workpiece can be up to 20-30 cm. The most significant disadvantage of this cutting method, in which the product is not subject to thermal effects, is the high cost.

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

    Drill bits can also be used for cutting and other materials

    “Steel beaver”

    Another popular drill bit that can be used to cut metal is the Steel Beaver. The principle by which such drill bits work is similar to how nibblers work. When using this device, sparks are not generated in the cutting area and no thermal effect is exerted on the metal sheet, respectively, the protective coating applied to it is not burned.

    Metal cutting attachment “Steel beaver” is completed with a replaceable die and a punch

    Among the technical characteristics of this type of drill attachment, it is necessary to highlight the following:

    • The efficiency of such a nozzle is ensured when the drill chuck rotates at a speed of 1500-3000 rpm.
    • The maximum workpiece thickness is 1.8 mm for conventional steel sheets, 2 mm for copper and aluminum sheets, 1.2 mm for stainless steel sheets.
    • The angle by which you can change the direction of the cut. 360 °.
    • Minimum cutting radius. 12 mm.

    When deciding which tool to choose for cutting sheet metal. a jigsaw, an angle grinder or a drill bit. you should first of all evaluate the tasks for the solution of which they are needed.

    Drill bits are a good option for DIYers and small construction crews. When the volume of work on sheet metal cutting is small, the use of such a nozzle is the best solution. When choosing this device, you should pay special attention to the fact that the characteristics of the drill, complete with which it will be used, correspond to the characteristics of the tool itself.
