Nozzle for a screwdriver for cutting metal tiles. Nozzle for screwdriver scissors. However, there is still a difference

It all started with the fact that I was going to change slate roof on a metal tile and sheathe the house with metal siding.

I went and bought everything I thought I needed. I am engaged in construction, but I have never worked with roofs, with painted galvanization either. Zero experience. But hands from where it is necessary to grow.


In general, the slate was removed, everything was prepared, sheets of metal tiles can be fixed. The roof is multi-pitched, a lot of trimming and fitting. As it seemed to me at that time, I would cut with an angle grinder, in the common people with a "grinder", ordinary cutting disc. And after the first attempt, doubt crept in, sparks flew in all directions, stuck to the coating and even burned it in places. It is no longer difficult to guess that in the place where the coating is broken, corrosion will appear very quickly and the meaning of replacing the roof will be irretrievably lost. I tried ordinary metal scissors, it's funny to remember how much time it would take me to go through all the corners, oblique cuts and fittings. Moreover, ordinary scissors are not at all designed for cutting metal tiles.


I started calling my friends. Friends explained to me that there are punching and cutting electric scissors that perfectly cope with such tasks. In the store where I arrived, they showed me a lot various models, everything would be fine, but the price turned out to be very biting. The cheapest 12.000 rubles. What's the point of buying them, what am I going to do with them? In the installation of plumbing and heating, (what I do) they have no use. In short, I was upset and, out of hopelessness, was about to fork out, when suddenly a man standing nearby and hearing our dialogue with a friend wrote the address of the store and the name "nozzle for a drill, nibblers for metal "Cricket" on a piece of paper


We arrived, twisted, turned, listened to a brief oral instruction manual and bought it. The purchase cost 1250 rubles, that is, ten times cheaper!

In 3 days we covered 200 square meters of roofing and sheathed the house with metal siding. The nozzle exceeded all my expectations. First, put the nozzle on the screwdriver, (1800 rpm) the cutting speed is slow and the quality is not super, burrs, uneven edges, already upset. Then they put it on an electric drill, (3000 revolutions) heaven and earth, the edges are smooth and the speed is completely satisfied. It is convenient to work with an uneven and sharply convex surface, as well as adjust the degree of inclination. The cricket handle is independent of the drill and rotates 360 degrees. Cuts sheet metal up to 1.6 mm like paper. Any hole in the sheet, please enter a 12 mm hole and you're done! I tried to cut two sheets of galvanized 1.0 mm, that is, 2.0 mm at the same time, and it cuts very decently. I also liked that there are two heads on the nozzle, on any of which you can screw the handle, and after it becomes dull, do not immediately change the matrix, but only turn it 90 degrees and change the cutting edge. This is done in three movements, loosen the screw with a special key, turn the matrix, tighten the screw. And in this small, in my opinion, indispensable tool in everyday life, everything is as simple as one, two, three!

To date, there is a great variety of various tools, the tasks of which include cutting and cutting thin-sheet material. One way or another, they cope with their tasks, but they have one feature - there are no universal metal scissors. Some devices are easily cut with flat sheet steel, others are great for stationary work, and still others, being household tool, barely cope with the task of cutting a drywall profile. The only exception is one device - cutting scissors, one of the options for which is the attachment for the cricket drill, which will be discussed in this article ..

How nibblers work

Submit your work nibblers quite simple - in fact, it can be compared with a chisel that makes breakdowns in metal with high frequency. Another comparison is the modern electric jigsaw, in which the standard saw blade with teeth is replaced by a punch rod (chisel). This principle of robots, combining a punching tool and a jigsaw, opens up wide possibilities and allows the use of a tool of this type even for figured cutting of sheet iron. It is for this reason that modern builders use a "cricket" for cutting:

  • profiled flooring;
  • any smooth steel, when we are talking about large amounts of work.

These are not the only reasons why the cleaver drill attachment has become widespread in the field of construction and repair.

Benefits of this tool

Another significant advantage of the cricket is its careful attitude to the protective and decorative coating or metal tiles. Punching through the material, it not only does not injure it along the edges of the cut, but, on the contrary, rolls it, thus protecting the end of the cut from corrosion. As a result, the metal lasts much longer.

Additionally as an advantage cutting metal nozzles for a drill, the following points can be distinguished.

  • High productivity – a 1 m long cut can be completed in less than a minute. Yes, the grinder cuts faster, but unlike the nozzle, it burns the protective and decorative coating.
  • What is the ability to overcome almost any obstacle. The wave and various bends are not a problem at all - you can direct the movement of the cutter not only left and right, but also up and down.
  • According to the manufacturers, this tool is able to easily handle metal up to 2 mm thick, which is quite enough to work with roofing materials.
  • The cost of the instrument can be called purely symbolic. It is at least five times lower than the price of professional cutting shears with built-in electric drive.

As for the shortcomings, the most significant is only one - it is almost impossible to achieve a perfectly even cut. In principle, it is not needed, since the edges in most cases are covered either by another sheet of metal or by special elements. If you try hard and come up with some kind of guide, then this problem can be solved.

Safety precautions when working with a "cricket"

In addition to the risks of cutting yourself on the edges of sheet iron, there are a couple more points that you need to beware of when working with a perforated drill bit. These are shavings - small and, most importantly, sharp fragments of metal in the form of a crescent. They can cause very serious trouble.

  • First of all, the shavings easily pierce into the legs, and this may not even be felt on hardened feet. Then suppuration begins and all the ensuing consequences. It is best to work with the tool in closed shoes.
  • The second point is, or rather, its impeller, which serves to cool the electric motor. Penetrating into the air intake hole, small metal crescents quickly disable the power tool. There is only one way to protect the drill - to pack it in a mesh material (for example, nylon tights).

In addition, we should not forget that small chips scattered around the yard quickly corrode, and if it remains, for example, on paving slabs, then rust eats into it and spoils appearance coatings. Timely cleaning of the workplace solves almost all issues.

What to look for when buying a "cricket"

Almost all tools of this type have the same design and work on the same principle - they are not provided with any additional options, and no additional devices are provided for them. Everything is simple - including the choice, approaching which you need to pay attention to just a couple of points.


In principle, decide for yourself what is best for you - cheap and cheerful or expensive, but for a long time. From practice, I can only say one thing - my first nozzle from Sparky worked in intensive operation without repairs and Maintenance within five years. By and large, we are not talking about such big money - a professional nozzle can be purchased for about 30-50 dollars.

In conclusion of the topic, the attachment for the “cricket” drill, it remains to add only one thing - to remind you that it is possible to extend the life of any tool through proper care of it. Every self-respecting master should clean his "breadwinners" at the end of work and control their technical condition. Naturally, one should not forget about caring attitude to the tool - hammering nails with a nozzle and generally using it for other purposes is simply wrong.

Nozzle-scissors "Cricket" Enkor 14210 is used in conjunction with any drill. Designed for cutting metal up to 1.6 mm thick. It is fixed in the cartridge, which drives the nozzle mechanism. Works on the principle of cutting scissors. Allows both linear and figured cuts, suitable for cutting material during ventilation and roofing work.


Nozzle for cutting metal "Cricket" manufactured by Enkor is intended for installation on devices with a rotary chuck - they can be represented by drills or even small ones.

Due to its design, it is able to completely replace specialized scissors, carrying out easy cutting of steel, aluminum and other metal sheets. The advantage of the model is small dimensions, low weight, as well as a well-thought-out design that minimizes the percentage of torque losses.

Characteristics of the scissors nozzle "Cricket" for metal up to 1.6 mm Enkor 14210

The device is designed to complete screwdrivers and corded drills that have a power of at least 0.4 kW - this indicator is average for this category of tools. This somewhat limits the scope of its application, since devices with a less powerful drive may be presented on the market. The internal mechanism is a standard hex shaft - such a shaft provides a more secure fit than a round one and has a much lower chance of slipping.

The maximum thickness of the cut steel sheet, not subjected to additional processing, is 1.6 mm. When working with alloyed or high carbon materials, the manufacturer recommends reducing given value up to 1 mm. If the operator needs to work with aluminum, copper and other relatively soft metals, then the sheet can have a thickness of 2 mm. Thanks to this, the "Cricket" nozzle is a good alternative to the traditional hand tool. The width of the cut path does not exceed 1.6 mm - this value allows for significant material savings when performing complex work with small objects.

Also, the functionality of the device includes the possibility of pre-drilling holes with a diameter of at least 11 mm. The length of the nozzle is 180 mm, which makes it possible to work in confined spaces with the maximum level of convenience.



Features of the nozzle-scissors "Cricket" Enkor 14210

The undoubted advantage of the nozzle for metal is the absence Supplies, as opposed to cutting wheels for grinders and jigsaws. "Cricket" will help not only quickly cut sheet metal, but also quickly make a hole of large diameter in sheet metal. Also, using this nozzle, you can cut holes of arbitrary shape from pre-cut drilled holes 11 millimeters in diameter. In addition to all of the above, it is important to point out that the Cricket nozzle is very simple and convenient to use, does not require adjustment at all, which means that even a beginner can easily master it, and a professional will appreciate the convenience and speed of work.

For more reliable fastening of the device, a plastic handle and a punch are used - they are included in the delivery. This allows you to significantly improve the accuracy of performing permissible types of work. A weight of 0.4 kg does not significantly increase the load on the operator's hands compared to the dead weight of the appliance. Drill attachment for cutting sheet metal up to 1.6 mm thick. Works with any drill.

At correct selection the number of revolutions of the drive shows excellent cutting results: it does not crease the edges of the metal, and at the same time they do not turn out sharp.

Features of metal scissors Enkor 14210

  • Ideal for punching holes in false ceiling(panels) for spotlights.
  • For working with metal sheets up to 1 mm thick.
  • Well cuts not thick metal 0.3-0.4 mm.
  • Be sure to use safety goggles and gloves.



Advantages

  • Suitable for cutting metal tiles, both along and across the wave.
  • Cut edge without burrs.
  • Does not heat or melt the coating
  • It is indispensable for working with a painted sheet, metal tiles, which are not allowed to be cut with a grinder.

Or a hacksaw is not available, then you can use an electric drill with a special nozzle for this purpose. 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 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:

  1. Better cut surface quality.
  2. The device allows you to make a hole in the metal of any shape.
  3. Significant cost savings due to the lack of spending on consumables.
  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 a rechargeable battery, it can be carried out in places where it is not possible to connect to a 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 a universal device 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.

Beaver has slightly better cutting performance 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 not deformed when subjected to constant loads. Among the variety of both domestic and foreign manufacturers, the 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.

Price for 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. It is indispensable when working with roofing metal materials, since, unlike angle 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 the effective operation of the nozzle, the manufacturer recommended the optimal drill speed of 3,000 rpm.

The estimated cost of EDMA NIBBLEX in the Russian market is 5,000 rubles. The high quality of the device is confirmed by numerous tests by both 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.
  5. Tools should be stored in rooms where the possibility of metal oxidation due to high humidity will be excluded.

HRM is analogous executive mechanism cutting scissors. It works on the principle of a die cutter. The source of movement for it is the electric motor of the drill. The rotational movement from the cartridge is transmitted to the connecting rod-crank mechanism of the nozzle. This mechanism converts it to reciprocating and sets the punch in motion. The latter creates a cutting line of the desired shape and width.

Taking into account the coincidence of the schemes of operation of the actuating mechanism of shears and HPM, we will consider the principle of operation of the latter using the example of the kinematics of electric punching shears.

Explanation for the figure:

1 - matrix holder;

2 - matrix;

3 - punch;

4 - slider;

5 - connecting rod;

6 - crank shaft;

7 - electric motor.

The rotation from the electric motor 7 (through a two-stage cylindrical gearbox) is transmitted to the shaft of the crank mechanism 6. From it, the reciprocating motion is already transmitted through the connecting rod 5 to the slider 4. The punch 3 is fixed in the slider, and the matrix 2 is in the die holder 1. The material to be cut is placed into the gap between the die and the punch. When the latter moves down, it is incised and moves in the right direction (possibly in any direction). Successive cuts form solid line cut. The cut workpiece is separated along it.

What metal can be cut

The following metals can be machined with HPM:

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

What determines the quality of the cut

Enterprises, taking into account market demands, produce NRMs that operate on the same principle, but, of course, various designs. They have different specifications:

  • some NRMs are designed for strictly defined grades and sizes of materials, have simple design higher reliability and lower cost. Devices of this group provide higher quality products. But if necessary, cut various metals, you should purchase a whole line of such devices. Therefore, they are used in the mass processing of metal of the same size;
  • others are universal nozzles"for all occasions". They are more complex, more expensive and the quality of processing on them is somewhat worse. To receive best quality products, you should choose a tool with a set of dies and punches.

You need to work with nozzles carefully so as not to damage the surface of the sheets. It is very important to choose the right number of revolutions of the drill. This will allow you not to crush the edges of the metal, and they will turn out sharp. For example, for metal of small thickness it is better to use a drill with a speed of 2700 ... 3000 rpm. Proceed directly to the cut should only be when the armature of the tool has gained optimal speed.

Nozzle "Cricket" for cutting metal

Very popular device HRM "Cricket". Consider it using the example of the Enkor 14210 model, which can be used in conjunction with any drill.

HRM "Enkor 14210" is designed for cutting metal up to 1.6 mm thick. It is fixed in the cartridge, which drives the nozzle mechanism.

Works on the principle of cutting scissors. Allows for all types of cuts. The use of tool steel for its production makes it possible to ensure maximum strength. The design causes a low level of noise and mechanical losses.

Nozzle for a screwdriver for cutting metal "Steel beaver"

The second very popular HPM device is the Steel Beaver screwdriver bit.

It is designed for cutting flat and profiled sheets (for example: metal tiles, corrugated board, etc.). In the process of cutting metal NRM "Steel Beaver" does not burn the protective layer metal coating(does not form sparks), which ensures the safety of the anti-corrosion coating of the metal.

Characteristics of the NRM "Steel Beaver":

  • recommended rotation speed of the drill rotor, rpm: 1500…3000;
  • minimum cutting radius, mm: 12;
  • permissible changes in the direction and angle of the cut, degrees: 360;
  • maximum thickness of the processed sheet, mm:
    • steel - 1.8;
    • stainless steel - 1.2;
    • copper and aluminum - 2;
  • weight, g: 400.

Cutting metal with a screwdriver or drill: advantages and disadvantages

Compared to other equipment, HRM has a number of advantages:

  • high quality cutting with the ability to cut any shape;
  • high economy. It is explained by the fact that consumables are not needed;
  • high performance;
  • the ability to process many grades of metal;
  • comfortable operating conditions;
  • the ability to work in conjunction with an electric or pneumatic drill (a screwdriver is allowed);
  • does not require expensive maintenance.

However, despite all the advantages of NRM, it has disadvantages. To ensure high quality cutting, certain skills and dexterity are required. In addition, it damages adjacent sections of the workpiece and often becomes the root cause of corrosion.

What not to expect

In general, you should not think that HPM will always be a replacement for several tools. Unfortunately, its power is incomparably low compared to professional-level electric scissors. This attachment is not designed for effective processing of thick metal sheets. It should be remembered that the maximum that it can cut is a steel sheet 2.5 mm thick. In the conditions of professional and, moreover, industrial metalworking, a more powerful specialized tool should be used, among which the grinder stands out. This tool is capable of effectively processing metal workpieces of almost any thickness.
