Shortly after buying the Fiolent PM-5-720E electric jigsaw (see my review of the Fiolent PM5-720E electric jigsaw), it became necessary to cut several wooden bars with a cross section of 30x40 mm and cut a couple of fiberboard sheets. To perform this work, I purchased a Bosch T101B jigsaw file. This blade belongs to the clean for Wood series of blades manufactured by Bosch and is designed for clean cuts in softwood, block plywood, chipboard and fiberboard with a thickness of 3 to 30 mm. The blade is made from high carbon steel. Switzerland is indicated as the country of manufacture on the package with files. I sawed several wooden blocks into the required sizes using a Bosch T101B file, and tried to saw them at different amplitudes of the pendulum oscillation. With the pendulum turned off and at its minimum amplitude, the cut is perfectly clean, that is, the file fully justifies its belonging to the Bosch family of wood files designed for clean cuts. With sawing fiberboard, the saw also did an excellent job. The cut was perfectly clean, without scoring. I recommend the Bosch T101B jigsaw file for purchase.
