    摘要: A hand-held machine tool is provided. The hand-held machine tool includes a striking element that is accelerated along a working axis, and a guide for the striking element. A cushioning damper limits a motion of the striking element along the working axis and has an elastic damping ring. The damping ring has grooves running on at least one face side radial to the working axis.
