Abstract:
The hand-held power tool has a tool socket, a motor and a pneumatic striking mechanism. The striking mechanism has an exciter driven by the motor along a working axis, a striker coupled to the exciter via an air cushion, and an intermediate striker arranged between the striker and the tool socket in the striking direction. The striking mechanism also has a guide in which the intermediate striker is guided. The guide has a first sliding surface that guides a first section of the intermediate striker, and a second sliding surface that is arranged offset relative to the first sliding surface in the striking direction and that guides a second section of the intermediate striker. A radial dimension of the first section of the intermediate striker is greater than a radial dimension of the second section of the intermediate striker.
