Professional electrofret can cut wood up to 80-135 mm, steel – up to 10 mm, aluminum – up to 20 mm. The cost of Jigsaw is largely dependent on popular brand of power tools and additional functionality and make them in Germany and Czechoslovakia. Cutting Jigsaw construction material is a special sawing, which is contained in an electric motor. Sawing motion makes a vertical (reciprocating) with a frequency of up to 3500 strokes per minute. The mechanism is installed on the mounting platform (stove, floor), which is the directing and allows perform very accurate cutting of material, keeping a constant distance from the workpiece. In addition, the platform can be rotated 45 degrees to install the correct cutting angle.

The platform is usually made of steel, aluminum or plastic. For safe sawing of the work closes with transparent protective screen, which is made of organic glass (Plexiglas). Handle Jigsaw may be skoboobraznoy (which is the most common) and the mushroom-shaped. The quality of jobs is not reflected, but the mushroom-shaped easier to work on sloping planes, as the first option allows you to better see the cutting line. Basically choose the form of handles depends on personal preference. Cordless Jigsaw use without the possibility of connecting to the power supply. The presence of additional features multistage pendulum mechanism, which is present in all current models, according to Pielke additional horizontal movement (in the direction of cutting back and forth) and allows you to cut the material only when the upward movement.
