Stroke
The length of the stroke of the working blade of the jigsaw during operation. The longer the stroke, the more of the file will be in contact with the material in one movement; accordingly, at the same frequency of movement of the blade, a jigsaw with a longer stroke length will be more performant.
Shoe sizes
The size of the sole of the jigsaw is a plane that, during operation, is closely pressed against the workpiece and ensures its correct position relative to the saw blade. This parameter is important primarily for stationary models (see "Type"). On the one hand, a large sole makes it easier to work with large sheets of sawn material (especially if the thickness of such a sheet is small and it tends to bend); on the other hand, this indicator significantly affects the weight and dimensions of the unit. However, some manufacturers indicate the size of the sole for a portable tool.
Wood
Maximum cutting depth in wood, in other words — the maximum thickness of a wooden workpiece that a jigsaw can handle. This parameter characterizes not only directly the maximum thickness of the material, but also the performance of the tool as a whole: the greater the depth of cut, the higher the performance. In the case of wood for domestic use, a depth of about 70 mm is considered sufficient, deeper models are usually professional.
It is worth noting that the depth of cut is usually indicated for certain files recommended by the manufacturer for a particular material. The use of other canvases does not guarantee compliance with the claimed parameters, and in some cases it is even fraught with breakdowns and injuries.
