Abstract
A handheld tool with a pneumatically operated linear oscillating drive is provided. The handheld tool has a motor housing and a piston movable in the motor housing, which separates the two working chambers of the motor housing from one another. A piston crown faces toward one chamber of the two working chambers, with a compressed air supply line toward the motor housing and a slide valve, which controls an alternating supply of compressed air to one and the other of the two working chambers, and with an exhaust air opening in the motor housing. The handheld power tool is distinguished in that the piston additionally has a piston skirt facing toward the other chamber of the two working chambers.
