A machine tool, in particular a wood-working machine, with a tool for chip removal rotating in direction of rotation D and a suction hood covering the tool with a partially opened circumferential wall that has a radial spacing A from the tool and that has a suction nozzle for suctioning off chips. In the machine tool rotating air vortices directed in the opposite direction based on the direction of rotation D of the tool can be generated in the suction hood in the area of the suction nozzle during the chip removal.
