Drill attachment, screwdriver “Cricket” on Aliexpress: the best sellers and stores

Aliexpress is a huge online marketplace where thousands of sellers operate. Unfortunately, not all of them work honestly. Although the administration is actively fighting against scammers, there is still a risk of receiving a low-quality product or even being left without it. Therefore, it is worth learning how to choose stores for purchase. We talked about how this is done in the article.

Can't always find foliage finishing material required size and shapes. During repairs, installation of fencing made of profiled metal sheets, devices roofing you need to quickly cut this or that workpiece and adjust the standard element to the actual dimensions. For cutting, you can use an angle grinder, scissors, etc. cutting tool. If you don’t have it at hand or you are limited on funds, then there is an alternative – a cricket attachment for a drill.

Brief description

This is a removable mechanism that is installed on a standard chuck of an electric hand drill. It is designed for cutting flat and grooved metal sheets:

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

By appearance The cricket drill attachment resembles a steel blank cylindrical, with “fingers” sticking out in both directions. A cylindrical blank is a body through which torque is transmitted from the drill to two cutting surfaces. “Fingers” are paired dies 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 key, are supplied with the nozzle.

Operating principle

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

Scope of application

The attachment is widely used for cutting thinly sheet metal. Its design is specially designed to perform both straight and curved cuts. Having certain work skills, you can perform figured sawing along a complex trajectory.

Unlike corner grinder or metal scissors, the “cricket” is capable of cutting 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. Mostly profiled sheets are used, which are perfectly cut using this tool.

Positive properties

The cricket drill attachment is widely used thanks to a number of positive properties. It outperforms some power tools in terms of performance.

• Mobility. She has small size, much less than that of the Bulgarian. The attachment is easy to install and remove from the drill, making work easier
• High level of autonomy. The “cricket” has two full-fledged cutting matrices. If one fails, you can use the other. In addition, a third spare is included with the tool.
• Maintainability. There is no complex mechanisms, there is practically nothing to break. The cutting part is supplied as a ready-made unit, which is easy to install on site
• Speed ​​of work. Numerous tests show that the performance and sawing speed of the attachment are significantly superior to those of an angle grinder. Metal scissors cannot be compared 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 cutting area remains smooth. There are no burrs on it. The metal does not heat up, protective polymer coating 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 an angle grinder involves the formation of sparks that fly over a considerable distance. If a galvanized profiled sheet is processed, sparks burn out protective coating. During use, the metal will become covered with brown spots of rust. Sawing with the dragonfly attachment takes place in the complete absence of sparks. No rust problems
• Ergonomics. Handle holder makes working with the tool convenient and safe

Negative properties

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

• Limitation associated with the type of grip. He only has two hands. Therefore, it is impossible to perform operations on inclined planes where to stay
• Metal thickness. Attachment designed for cutting thin metal

Safe work rules

Practically do not differ from standard measures when working with sawing tools:

1. Do not saw while holding the tool with one hand. This may cause it to bounce;
2. Before starting work, check the rigidity of the handle holder. To do this, it is turned clockwise until it stops.
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. Do not work with a faulty tool. These include: a loose drill chuck, a ground sawing matrix, a loose handle holder

Manufacturers

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

There are several companies worthy of attention on the Russian market:

• Anchor
• Corvette
• Sparky

Using scissor attachments on a drill greatly facilitates roofing work, installation of metal fencing, and other manipulations with sheet material. Convenient combination with hand drill allows you to reduce the cost of purchasing expensive specialized tools. Finished product It turns out neat and high quality.

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

Types of processing

Once upon a time, the only possibility of processing metal products was, but as technological progress developed, 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 tools.

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 cutting by burning in oxygen, directed in the form of a jet to the site of the intended cut. Melting does not occur - the material remains hard, resulting in an even cut.

There are also oxygen-flux and oxygen-lance options. In the first case, a flux additive is supplied to the cut site along with oxygen, which has a chemical, thermal or abrasive effect on the material, which facilitates the cutting process. With the oxygen-lance variety, the necessary 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 electrically heated material burn in an oxygen stream, and scale is blown away from the cut.

Gas methods are inexpensive, relatively easy to use, but do not provide high quality result: after them you need additional processing cut edges.

Plasma treatment is carried out using a plasma torch, which creates a plasma jet heated from 5000 to 30000 degrees. The latter method has a number of advantages compared to the previously mentioned:

1. Universality of application of the technique.
2. High speed and cutting accuracy.
3. Possibility of cutting along complex curved contours.
4. Higher level of environmental safety.

Among the disadvantages this method This includes the high cost of the equipment and the complexity of its maintenance, the noise of the process, and 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 your face and hands from sparks and hot splashes.

Harder than iron

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

These could be:

1. Scissors.
2. Accessories for electric drills.

When cutting metal sheets, the first type of tooling is usually used. Known the following types scissors:

• manual metal cutting shears;
• splined, powered by an electric motor;
• guillotine – manual and mechanical type.

The guillotine type is equipped with a single oblique blade moving in one plane at an angle, thanks to which you can work without applying as much force as when working with conventional roofing scissors.

Saws are electrically driven and are divided into:

• saber;
• disk;
• angle grinders.

Sabers are supplied with a set saw blades length from 100 to 300 mm, moving along a reciprocating trajectory. When working with them, you need a good eye.

Cutting part circular saw is a disk, 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 reliable fastening. The lightweight body is made of aluminum, the knives are made of high-strength steel. Design features provide the ability to rotate to any angle.
2. TurboShear (perforated) MALCO TSMD EV – suitable for cutting metal products up to 1.2 mm and cutting corners up to 90 degrees. Provides a perfectly straight cutting line on both sides.
3. Black&Decker MTS04 – designed for grinding. Also, this drill attachment is suitable for cutting wood and plastic. The tool is intended to be used for repair and construction work at home.
4. TurboShear MALCO TS1 EV – involves cutting steel sheets up to 1 mm thick. The fastening is provided by the shank. Aluminum body. Carbon steel knives. Working with this part is possible only with both hands.
5. Scissors NP 1.8 SPARKY 181874 – suitable for any model of electric drill. Capable of performing linear and radius cuts, allows cutting non-alloy steel.

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 grinders.

While engaged in construction or repair work, almost everyone is faced with the need to cut some kind of metal workpiece. To perform this procedure, you can use a grinder, a milling cutter, hand scissors on metal.

But what to do if you need to cut a metal sheet, but there are no such tools at hand? You can solve the problem using an ordinary drill and a special attachment, which can be bought at any hardware store.

What are metal cutting attachments?

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

Thanks to the targeted effect on the metal, the integrity protective layers products are preserved as much as possible.

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

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

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

Advantages of attachments

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

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

Special attachment “Cricket” for a drill for cutting metal

Construction stores They offer several types of drill attachments for cutting metal.

Nozzle "Cricket". The “Cricket” device is a nibbler (cutting) scissors that can make an even cut. The tool is used for cutting not only smooth, but also profile metal sheets.

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

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

Using the Cricket attachment you can cut on horizontal and vertical surfaces, as well as make internal cuts. To ensure a high-quality internal cut, the workpiece must first be drilled.

The tool is indispensable when performing roofing work that requires processing of metal tiles or corrugated sheets. After using Cricket, the materials used will not be deformed, and the cut will be smooth and beautiful.

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

Nozzle "Steel beaver"

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

In the process of metal processing using a tool " steel beaver» no sparks are formed and the protective layer of the metal coating is not burned.

Key Features:

• 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 have a thickness of no more than 1.2 mm;
• maximum thickness steel sheet can be up to 1.8 mm;
• change of cutting direction and angle – 360 degrees;
• minimum cutting radius – 12 mm.

Models of drill attachments and their use

Special attachments The drill can make both straight and curved cuts. Do curly cuts for installation of gutters drainage system or roof ventilation parts, cut in vertical and horizontal directions.

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

On construction market Drill attachments are available in several models:

• ACCO YT-160A.
• EDMA NIBBLEX.
• Sparky NP 1.8 L.
• "Cricket" from the manufacturers Enkor.

By and large, all models of drill attachments operate according to the same parameters. An exception may be the thickness of the metal sheet that a particular tool can cut.

After using the devices, the edge is obtained sharp, smooth and not wrinkled. You just need to make sure that the speed of the drill you use matches the characteristics of the attachment.

Those involved 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 an attachment.

For home craftsmen, this tool will become optimal solution and a great helper. It is worth keeping in mind that the cutting process can be entrusted to specialists who have experience and certain skills.

The compact Cricket attachment is installed on various powerful electrical appliances - in particular, screwdrivers, drills and rotary hammers. Thanks to the ability to cut sheet metal, it significantly expands their functionality, allowing you to perform more operations with one unit. The use of tool steel for its production makes it possible to ensure maximum strength and also allows you to work with a wide range of materials. In addition, the carefully designed design results in low noise and mechanical losses.

Operating characteristics

The power of the main device on which this device is installed should not be less than 0.4 kW - with this value, effective cutting is achieved without severe bending of the metal edge. This indicator corresponds to the parameters of the majority household power tools- both drills and hammer drills, and screwdrivers. The length of the device is 180 mm - due to this, you can work not only in ideal workshop conditions, but also in limited space. The power take-off mechanism is based on a hexagonal shaft, which has good grip properties and greater strength compared to traditional round shafts.

Due to the high quality of the tool steel used, the Cricket attachment can cut fairly thick metal sheets. For stainless steel this figure is 1 mm, and for softer alloys - 1.6 mm. When using aluminum, the thickness can reach 2 mm. Using the nozzle, you can also create round holes with a diameter of 11 mm or more. A special feature of the device is also the small width of the cutting path - it is only 1.6 mm. This provides a good level of metal savings that cannot be achieved using hand tools.

Peculiarities

The attachment does not increase the weight of the electrical appliance, since its own weight is only 400 grams. To the number additional benefits The delivery set includes a punch and a replaceable handle, with which you can increase the accuracy of the work.

The "Cricket" scissor attachment is designed for cutting sheet steel along a straight or curved line, for cutting holes of arbitrary shape from pre-cut drilled hole diameter 11 mm. The nozzle is powered by an electric or pneumatic drill.

Cutting is carried out according to the principle nibblers. The nozzle does not require adjustment and is easy to use and maintain.
