Cutting scissors for metal: an overview, types, manufacturers and reviews

In the plumbing and carpentry stillA mechanical tool for cutting metal is used to perform typical simple operations with soft sheet material. But quality figured processing of thick and corrugated products is impossible without the support of the electric drive. Such work with minimal expenses can be performed by the shearing metal scissors, also called punching scissors. This is a handheld device designed to cut not only sheet roofing materials, but also valves with pipes.

The design and operation of the instrument

Outwardly, such scissors resemble modernelectric screwdriver. The design provides a body of approximately the same dimensions, and even the electric drive has similar performance characteristics. Differential scissors for metal only with a cutting mechanism. It is represented by a punch used for reciprocating movements. During processing, the mechanism performs the deflection of the metal, cutting one of the parts of the workpiece on a sharpened matrix.

The compact dimensions of the scissors providemaneuverability, which makes it possible to carry out work operations under difficult conditions. This quality is especially important when working on the roof with a profile and metal. For the implementation of curvilinear cutting, the shearing metal shears "Cricket" are also used, which differ in the special nozzle inserted into the cartridge.

This device, by the way, can be used as an addition to a conventional electric drill - it is enough to compare the nozzle parameters with the characteristics of the main tool in advance.

Varieties of nibbling scissors for metal

All models of shearing scissors can be divided intohousehold and professional. They differ in performance. For example, modifications designed for home use, provide a cut in the range of 1-3 mm. This is enough to work with a thin roofing profiled without high corrugation. In professional working operations, metal nibbling scissors with a cutting depth of up to 5 mm are more often used. It is quite possible to implement the machining of reinforcement with such a tool. Regarding the quality of work, both varieties show similar indicators. The difference can be manifested only in operations with a problematic hard metal - in such cases it is desirable to abandon the use of low-power household models.

Reviews of the BN 503 from Sparky

Company Sparky offers universal nibblingscissors in the modification BN 503. According to users, this model qualitatively performs processing of metal and plastic products. The tool is given a curved cut if the target material is represented by a thin sheet.

The physical strength of the device is also noted -to increase reliability, the manufacturer provided the apparatus with a gear box made of metal. Due to the switch in the "Start" position, the processing process is much easier for the master. In addition, the Sparky metal cutting shears can be supplemented with an auxiliary handle, which is mounted on the left or right side to the user's choice. By the nature of the work, this model is still classified as domestic, because with hard steel sheets, for example, this tool does not without difficulty.

Reviews of the model JN 1601 from Makita

This is a more productive model, equipped withelectric motor for 550 watts. As practice shows, the Japanese tool is suitable for working with ordinary sheet, corrugated and corrugated trapezoidal metal. Owners of the device highly appreciate the possibility of turning the head 360 degrees. It can be fixed in four positions, the step between which is 90 degrees. Like all modern models of hand power tools, the Makita metal shear cutters of the JN 1601 version provide for the presence of carbon brushes that protect the engine from premature breakages.

Users of the model emphasize that the process of theirreplacement is greatly facilitated through open access. The advantages of the device include external ergonomics, which is facilitated by a comfortable grip, the presence of a fixed start button, as well as the limiting grooves that relieve the master from controlling excessive depth of cutting.

Reviews of the model GNA 3,5 from Bosch

German designers are known as manufacturersA quality tool that combines both functionality, performance, and durability. According to those who use the model GNA 3.5, it fully meets these characteristics. The high power potential of 620 watts makes it possible to work at a professional level. Practice shows that the tool effectively works with a cutting thickness of 1.6 to 4 mm. At the same time, the device is free from the drawbacks inherent in high-power units.

In the process of work, shearing scissors for metalproduce a minimum of noise and do not cause discomfort with the vibrating effect, which contributes to a qualitative cut. The minuses of this modification include a large weight of 3.5 kg. But to compensate for the load, the manufacturer also provided for the possibility of completing the structure with a convenient grip.

Conclusion

Availability in a private sector of specializedtool for cutting metal products, of course, is a good help in the process of performing repair work. Repairing the roof, assembling the fence from the corrugated board and even cutting fine fixtures - all this helps to perform hand-cutting metal scissors, without requiring the connection of specialists. But the cost of this tool is quite high and on average is about 10-15 thousand rubles. Professional modifications and may cost 30-40 thousand. Of course, for rare and occasional events such an acquisition may seem superfluous, but do not forget about the quality of metal processing that no other tool from the household segment can provide.
