Electric scissors for cutting metal and pipes
The need to cut metal or pipes arises during various construction and repair work. In the process of using special scissors, manual or electric. When the amount of work is large, it is more efficient to use a household power tool.

The advantages of using electric shears for metal
Scissors for metal - the necessary tool in the household. With their help, cut and tailored sheet metal, roofing materials, gutters, fabricate metal frames, decorative elements from tin. They can be cut into wire, metal mesh. In repair work, this tool is second only to a hammer, saw and drill.
And for the master roofers, tinsmiths, plumbers, ventilation installers, electric shears for metal is one of the important tools due to a number of advantages.
- In comparison with the manual analogue, the performance is several times higher.
- Electroscissors for metal without any problems cope with any sheet thickness: 3-5 mm and even higher.
- Tool can be cut out curvilinear elements.
- High precision cutting without chipping and deformation of the material.
- Manual efforts are not required, cuts and calluses on hands are excluded.
Types of electric shears for metal
Electrical appliance is dressed outside in an elongated body made of impact-resistant plastic. Under it is an electric motor that drives a multi-stage gearbox. This mechanical assembly is protected by a metal casing. Principle of operation simple: the gearbox converts the rotational movement of the spindle into the reciprocating movement of the cutting unit.
Depending on the method of impact on the metal sheet of the working part, the manufacturers offered electric shears are divided into three types:
- leafy;
- spline;
- cutting
The scope of these three variants of cutting power tools, respectively, also differ.
Sheet scissors
The working mechanism of the sheet device is arranged by the principle of ordinary scissors: the static knife is fixed horizontally, and the movable blade is working in the perpendicular direction. There is a function to adjust the gap between the blades. Leaf models differ in performance. It is effective to use such a tool for the dismantling of metal structures, for cutting iron 4-5 mm thick, for cutting metal folds, wire. When using sheet shears there will be no waste in the form of spiral chips.
The lack of design - the ability to start cutting only from the edge of the sheet, with their help it is difficult to make curved cuts and profile blanks.
Slotted shears
The cutting structure is composed of a fixed blade U-shaped and a lower knife progressively moving along the vertical, which enters the U-shaped groove. There is also an adjustment of the gap between the blades. Models of this type cope with sharp sheets up to 2 mm thick. They can be cut anywhere on the workpiece, and can also be used to cut holes. The model is mobile, suitable for use in hard to reach places.
The disadvantage is the formation when cutting metal thin spiral chips, which periodically need to be removed with nippers.
Cutting Scissors
This type of metal cutting equipment is also sometimes referred to as nibbled electric shears. This tool represents notched press in miniature, moved on the canvas with the handle. The cutting mechanism consists of a static matrix and a moving part of the snap-in. The cutting mechanism can be round or square.
The round cutting cutting mechanism is used for thin metal blanks, and the square one - for a thicker sheet.
This tool is versatile and mobile, great for cutting metal tiles. Performs a clean cut anywhere on the sheet. In the cutting process, waste is collected in the form of sharp small chips.
Recommendations on the choice of scissors for metal
When choosing a suitable tool model, it is recommended to pay attention to the following characteristics.
- Sheet metal shears can be with right and left lower blade position. The left scissors are suitable for right-handers, and the right for left-handers.
- Pay attention to the parameter maximum cutting thickness. You need to choose a tool suitable for the material that will have to be cut.
- Models differ in material qualityThe blades are made of: chrome-vanadium are resistant to corrosion and are rather durable. There are models with knives of chromium-nickel, as well as high carbon steel.
- Need to pay attention to scissor length. This parameter affects the mobility of the device.
- Power type (mains or battery) and power.
- Ergonomics and accessories.
Choosing electric shears for pipes
In the repair and construction works, craftsmen sometimes have to perform cutting on propylene: it is from this material that pipes are made for the organization of water supply to the premises, as well as the construction of heating systems. Sales of pipes, as a rule, are 12 meters each, and for installation, they need to be cut to the desired size.
For polypropylene pipes, the industry also produces professional hand and cordless scissors. The following types of tool can be distinguished.
- Manual ratchet precision scissors, equipped with a steel blade and a serrated bar.
- High performance automatic pistols that allow pipes to be cut to half a meter in diameter.
- Roller pipe cutter with a disk blade or ratchet mechanism, which allows to make high-quality smooth cut.
- Battery models with high speed. Recommended for professional use only.
When choosing such electric shears, one should take into account the maximum diameter of pipes with which one has to work and the material of the blades. As a rule, for plastic pipes choose stainless steel.
For one-time repair work, there is no sense in buying special scissors for pipes: pruning can be done with a regular hacksaw.
Overview of popular brands
In the assortment of the Japanese brand Makita sheet, cutting and slotted electric shears are presented. The purpose of the tool is cutting aluminum and steel blanks of various thicknesses. For precise adjustment of the cutting depth, an integrated thickness gauge is provided. Models differ in quality of the equipment, the thought over ergonomics the high level of safety.Depending on the capacity, size and type, prices vary in the range of 15 000 - 30 000 rubles.
More affordable Russian brand tools Bison and Interskol. Depending on the model, prices vary from 5,000 to 10,000 rubles. If we talk about professional electric shears for metal, then you should pay attention to highly specialized manufacturers.
