Nozzle scissors cricket for cutting metal. Nozzle for a drill "cricket" and other "usefulness" with detailed descriptions. Thicknesses of materials that the scissors can cut

HPM is an analogue of the actuating mechanism of punching shears. 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 notches form a continuous cut line. 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 more high quality products. But if you need to 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. For getting 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, the NRM "Steel Beaver" does not burn protective layer metal coating(does not form sparks), which ensures safety anti-corrosion coating 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 electric scissors. professional level. This attachment is not designed for effective processing of thick metal sheets. It should be remembered that the maximum that it can cut is steel sheet 2.5 mm thick. In the conditions of professional and, moreover, industrial metal processing, a more powerful specialized tool, among which the Bulgarian stands out. This tool is capable of effectively processing metal workpieces of almost any thickness.

To the entry "Nozzle for a drill for cutting metal" 2 review(s).

Leave your review

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

There are a great many tools that can be useful in everyday life or for infrequent custom work. In order to buy, for example, the so-called "grinder", you will need a considerable amount, and in the meantime the tool will lie somewhere in the garage or workshop idle, being unclaimed.

Not every tool designed for a particular job, a person is able to buy: it will take a lot of money and extra storage space. And, as practice shows, there is simply no point in this. But there is still a way out of this situation.

Nozzles are for the following works:

• Drilling at an angle;
• grinding;
• Polishing;
• Sharpening nozzles;
• Drilling;
• For cutting metal.

As can be seen from what has been said, having only one drill and a few nozzles, you can thus replace a lot of expensive tools and not waste your money.

Basic Sheet Metal Cutting Methods

Sooner or later, every homeowner, not to mention specialists, cuts sheet metal in one scale or another. Ever since labor lessons at school, and for many after, in production, such tools for cutting metal are known:

But time goes by and technical progress does not stand still. Mankind has invented a simple and inexpensive cutting tool that works in tandem with an electric drill called "metal nibbling scissors". This equipment is simple, constructive and very convenient in operation.

When there is one in the tool arsenal of any man, as well as an electric drill, then there are no problems with cutting a metal sheet and cannot be.

And if there is none on the farm, then it can be purchased at the nearest household or construction market.

Good alternative to Bulgarian

This drill attachment has been helping out craftsmen for many years now. Such a tool is called nibbling scissors.

Easily punches a track about 3 mm thick in metal. This cutting method gives the desired cleanliness of the cut, and there is no particular need for further cleaning of the cut.

Thicknesses of materials that the scissors can cut:

• Copper and brass - 1.5 mm;
• Aluminum - 2 mm;
• Stainless steel - 0.8 mm.

For metalworking

These nozzles are scissors simple and original design, where rotary motion the drill chuck is converted to reciprocating.

Nibblers "Cricket"

The technical capabilities of the "Cricket" nozzle allow cutting metal and plastics. Moreover, the material can be cut both sheet and profile. Two cutting heads of the cutting nozzle on the drill allow cutting materials certain thickness (specified maximum thickness):

1. For aluminum - 2 mm;
2. For steel - 1.5 mm;
3. For stainless steel - 1.2 mm;
4. For plastic - 2 mm.

Additional characteristics:

• Electric drill power from 420 W;
• Turnovers - from 3000 rpm;
• Cutting radius (minimum) - 12 mm;
• The cutting direction is unlimited, hence 360 ​​degrees.

Application area:

1. Mounting;
2. Roofing works;
3. Production of gutters;
4. Disassembly of various structures;
5. Body work;
6. Curly (decorative) cutting.

When working with nibblers, the drill does not require any adjustments and special skills and knowledge.

The Cricket tool for cutting metal is very maneuverable, and its capabilities are cutting tool are very wide.

As for cutting with a grinder, there are a number of disadvantages here, compared with cutting shears for metal. The nozzle on the drill has a number of significant advantages:

• The material does not overheat during cutting, which is especially valuable when cutting metal tiles.
• Maneuverability nibblers for a drill is much higher than that of a well-known grinder.
• Higher cutting speed.
• A cleaner saw cut that rarely requires further plumbing.
• When working with nibblers for a drill, there are no jamming of the tool from distortions, which very often happens when working with a grinder, hence the almost complete absence of injuries.
• Zinc does not burn paintwork material, which helps prevent premature corrosion and, most importantly, maintain the warranty on the material.
• When working with the Cricket tool for cutting metal, there are no sparks, unlike a grinder, which not only protects the material from burning, but also eliminates the possibility of injury to the eyes of the worker.

Nozzle-scissors "Cricket" has a number of analogues, for example:

1. "Beaver";
2. "Steel Beaver";
3. Scissor attachment NP 1.8 SPARKY;
4. EDMA NIBBLEX;
5. Malco turboShear TS1 - can be used with a drill and for installation on a screwdriver.

All of the listed nozzles have some differences on technical specifications and prices. The most expensive nozzle is Malco turboShear TS1. It has a slightly different design and is made in the USA, not China.

It should be noted that normal work of these devices can only be provided with a passport drill speed of more than 2700 rpm.

Nozzle for screwdriver

If an electric drill is not available, then a screwdriver can also perform the same functions.

There is, however, a difference:

• The revolutions of a screwdriver are lower than those of a drill. Low speed and, accordingly, the power of the power tool will not allow cutting metal with the same productivity, especially if it is closer to 2 mm in thickness.
• Lack of inertia. After the user releases the button, the chuck immediately stops rotating. In terms of safety, this is even somewhat better, as well as in the case of a figured cut.
• Small size and light weight compared to a drill. This allows you to do all sorts of "pirouettes" when cutting, more easily than with a drill.
• Screwdrivers run on batteries, therefore, its operation is autonomous, and power cord does not interfere with normal operation.
• There is no adjustment of the rotation speed of the cartridge.

It is quite clear that a screwdriver can also be used instead of a drill with a Cricket type nozzle.

For cutting metal tiles and more

This nozzle is a real find for cutting material such as metal tiles.

Advantages:

1. Does not damage the material and coating;
2. Easily follows the contour of the material profile;
3. Able to make cuts of varying complexity.

"Cricket" is a real find for both the handicraftsman and the professional. It can make an internal cut and can work both horizontally and vertically.

The nozzle for cutting metal tiles allows you to cut metal tiles and corrugated board, with which this tool does an excellent job. After all, it is well known that it is difficult to work by making cuts in these materials with another tool, and the Cricket copes with this task perfectly: cleanly, quickly and without errors.

Advantages and disadvantages

Advantages:

• Surface cleanliness is better than that of a grinder.
• This device can make holes ("windows") of any complexity in the metal.
• The tool is easy to use and maintain, takes up little storage space.
• Low price.
• You can cut both metal and plastic, as well as carbonate of a certain thickness, stated in the instructions for use of this equipment.
• The possibility of using the device in places where there is no power supply is compensated by the presence cordless drill. In addition, it can be successfully used in damp rooms, where using an electric drill from the mains is life-threatening.
• The device is multifunctional.
• The low weight of the device is also an undeniable advantage.

Of the shortcomings, there is the only and main one: the device must be held with both hands, which is not always convenient and safe when working at height.

In conclusion, I would like to summarize what has been said. Any user, both beginner and experienced, who does not want to overpay for a fabulously expensive tool, can always buy an inexpensive analogue that will pay for itself very quickly by performing the same functions.

Very often it turns out that suddenly there was a need to use a cutting tool, and it was not included in the plans to buy something expensive, which is not known when it will be needed (if it is needed at all).

AT this case it is cutting shears for metal that will come in very handy.

That's why cutting attachment found on a drill wide application in many branches of human activity: repair, assembly, dismantling and restoration.

Good luck with your purchase and enjoy working with the Cricket attachment for metal cutting!

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 curly 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 hexagon - such a shaft provides more secure fastening than round and has a significantly lower chance of slippage.

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 this value 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 track 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, a counterweight cutting wheels for grinder and jigsaw. "Cricket" will help not only to quickly cut sheet metal, but also to quickly make a hole 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.
