Craftsmen who cut sheet metal with hand shears know that this is a very laborious process, but it is also dangerous. And it’s not worth talking about cutting corrugated or profiled material. In this case, metal shears are ready to come to the rescue of professionals and amateurs. This tool is quite simple to use, for which you do not need much effort, since chopping or cutting is done automatically. When using such a unit, a fairly even cut line is obtained. Electric shears for metal are able to cut even three-millimeter material. It is worth considering what types they are.
All modern electric shears for metal can be divided into three types:
- slotted;
- punching;
- for cutting sheet steel.
The generally accepted selection criteria are performance, power, equipment, reliability and functionality. Here you can give standard recommendations, which are based on the principles for choosing similar tools based on an electric motor. There is only a certain difference in terms of endurance, durability and reliability of the tool. In this sense, it would be best to focus on manufacturers who have already managed to prove themselves quite well: Bosch, Hitachi, Makita and ZUBR. It is worth saying that metal shears differ in terms of production compatibility, so some of them are suitable for some specific purposes, while not at all suitable for other tasks. This is the starting point.
Shears for sheet steel are usually more modest in size, and they are usually used for precise cutting of not the thickest metal. Such a tool is very easy to manage, it is accurate, fast in operation, quite productive and reliable. When cutting metal, no waste is left. According to the principle of operation, such scissors do not differ from manual mechanical tools. The material is located between a pair of knives, while one of them is movable. When you turn on the device, it moves, cutting the metal. Such models allow you to adjust the gap between the cutting parts, so that the tool can be optimally adjusted to work with specific types of materials. Electric shears for metal "Interskol" have proven themselves very well.
Punch type is great for cutting profiled materials or creating holes of different sizes and shapes in materials. Such scissors are distinguished by their cutting part, which includes a punch and a fixed matrix. The movements of the punch are similar to how a hole punch works. The main advantage that this type of tool can boast of is the ability to start cutting from any point in the material. Higher maneuverability is another advantage of such a device.
Makita Slotted Electric Shears are a tool that is considered ideal to work with, as they can be used to obtain the highest quality cut. With such a device, you can perform the widest range of installation work.
In general, the choice of one type or another depends entirely on the tasks that you face.
