Nozzle cutting scissors for metal. Nozzle-scissors for metal cricket, metal case. Homemade nozzles for a drill - video

How to cut metal at home? In 90% of cases, with hand scissors (we are talking about thin metal sheet). The method is simple, inexpensive, but not without drawbacks.

At a minimum, it is quite difficult to make a long cut without burrs.
Since the scissors are located along the sheet, the cut planes need to be spread up and down. This makes it difficult to work, not to mention the fact that the edges subsequently need to be aligned.
If the workpiece is not flat, but with stiffeners (for example, corrugated board, or a figured "under the tiles" roof covering), it is almost impossible to cut with ordinary metal scissors.

It takes a lot of physical effort. If you need to cut several meters at a time, then you get a good workout, like in a gym. Often, a grinder with a cutting disc is used for such work.

It turns out quickly, relatively evenly and not at all hard physically. However, the edges require post-treatment and the metal at the edge is exposed to undesirable thermal stress.

If you are working with sheets of profiled metal-plastic "tiles", then protective layer in the place of the cut, it burns out and loses its aesthetic appeal.

progressive way- electric scissors for metal with a vertical arrangement of blades. However, this is an expensive tool that is rarely used (how often do you re-roof?). Therefore, there are more practical devices on sale: a nozzle for a drill for cutting metal.

In fact, this is a reducer that converts rotary motion spindle into oscillatory. Of course, in terms of its characteristics, the device is inferior to full-fledged electric scissors.

However, the drill attachment is inexpensive, and besides, you do not buy a ready-made tool (scissors with a motor), which most of the time gathers dust on the shelf. There is a drill in almost every home, if necessary, it can be easily turned into a progressive cutter.

Varieties of nozzles

The classic nozzle on the drill - scissors for metal. Second name: "beaver".

Doing construction or repair work, almost everyone is faced with the need to cut any metal blank. To perform this procedure, you can use a grinder, cutter, hand shears for metal.

But what if it is necessary to cut a metal sheet, but there are no such tools at hand? You can solve the problem with an ordinary drill and a special nozzle that you can buy at any hardware store.

What are metal cutting tools?

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

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

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

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

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

Nozzle benefits

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

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

Special nozzle "Cricket" on a drill for cutting metal

Construction stores offer several types of fixtures for drills for cutting metal.

Nozzle "Cricket". The "Cricket" device is a cutting (cutting) scissors that are able to perform an even cut. The tool is used for cutting not only smooth, but also profiled metal sheets.

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

The maximum thickness of sheet steel should be 1.5 mm.
The maximum thickness of stainless steel is 1.2 mm.
The maximum thickness of copper and aluminum is 2 mm.
The thickness of the plastic is 2 mm.

With the help of the Cricket attachment, you can cut on horizontal and vertical surfaces, as well as make internal cuts. In order for the internal cut to turn out to be of high quality, the workpiece must first be drilled.

The tool is indispensable when performing roofing works, during which it is required processing of metal tiles or corrugated board. After applying Cricket, the materials used will not be deformed, and the cut will turn out to be even and beautiful.

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

Nozzle "Steel beaver"

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

During metalworking with the Steel Beaver tool sparks are not generated and the protective layer of the metal coating is not burned.

Main characteristics:

cutting is performed at a drill rotation speed of 1500–3 thousand rpm;
the maximum thickness of aluminum and copper sheet should be 2mm;
stainless steel sheets must have a thickness of not more than 1.2 mm;
maximum thickness steel sheet can be up to 1.8 mm;
changing the direction and angle of the cut - 360 degrees;
the minimum cutting radius is 12 mm.

Models of nozzles for a drill and their application

With special nozzles for drills, you can perform both straight and curved cuts. Do curly cuts for installing gutters drainage system or ventilation parts of the roof, cut in the vertical and horizontal direction.

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

In the construction market, nozzles for a drill are represented by several models:

ACCO YT-160A.
EDMA NIBBLEX.
Sparky NP 1,8 L.
"Cricket" from Enkor manufacturers.

By and large, all models of nozzles for a drill work according to the same parameters. An exception may be the thickness sheet metal, which can be cut by a particular tool.

After applying the devices, the edge is obtained sharp, smooth and not wrinkled. It is only necessary to ensure that the speed of the drill used matches the characteristics of the nozzle.

Those who are engaged in construction or repair sometimes need to cut metal. And, if it is not possible to purchase an expensive tool, then the cutting process can be entrusted to a drill with a nozzle.

For home crafters, this tool will become optimal solution and great helper. It should be borne in mind that the cutting process can be entrusted to specialists who have experience and certain skills.

The compact nozzle "Cricket" 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 large quantity 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 crafted design results in low noise and mechanical losses.

Performance 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 a strong bend in the metal edge. This indicator corresponds to the parameters of most household power tools - both drills and rotary hammers, and screwdrivers. The length of the device is 180 mm - due to this, it is possible to work not only in ideal conditions workshop, but also in a limited space. The power take-off is based on a hexagonal shaft, which has good traction and is stronger than traditional round shafts.

Due to the high quality of the tool steel used, the Cricket nozzle can cut rather 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. With the help of the nozzle, you can create and round holes, whose diameter is 11 mm or more. A feature of the device is also the small width of the cut track - it is only 1.6 mm. This provides good level metal savings that cannot be achieved using hand tools.

Peculiarities

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

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

Cutting is carried out according to the principle of nibbling scissors. The nozzle does not require adjustment, is easy to use and maintain.

Or a hacksaw is not available, then you can use it for this purpose electric drill co 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 have not only a large number of advantages, but also limitations, the main of which is the thickness of the material with which you can work.

The use of such equipment can be not only in the absence of alternative way process the material, but also in the case when heating the metal sheet is undesirable.

Among the main advantages of using a nozzle on a drill, before using a grinder, the following can be distinguished:

Better cut surface quality.
The device allows you to make a hole in the metal of any shape.
Significant savings Money, due to the lack of spending on consumables.
The tool is very easy to use.
Many nozzles allow you to work with both metals and plastic sheets of appropriate thickness.
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.
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.
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. Restriction on maximum thickness 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.

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.
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.
Nozzles for Russian-made drills are practically not inferior in quality to foreign counterparts, while the price may differ significantly downwards.
It is not recommended to purchase devices from your hands, you can buy defective goods for a lot of money.
Tools should be stored in rooms where the possibility of metal oxidation due to high humidity will be excluded.

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 and fence installation. 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. 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 a grinder is associated with the formation of sparks that scatter over a considerable distance. If a galvanized profiled sheet is processed, then sparks are burned out protective covering. 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:

Do not cut while holding the tool with one hand. This may cause it to rebound;
Before starting work, the rigidity of the fastening of the handle-holder is checked. To do this, it rotates clockwise until it fails.
It is allowed to work only in protective glasses and gloves;
It is recommended to cut the sheet away from you, and not towards you;
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 on 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.
