Abstract

The invention relates to a percussion mechanism for an at least percussively-operated hand machine tool, in particular a hammer drill or chisel, comprising a drive motor and a tool holder ( 10 ) for housing a tool, with a percussive pin ( 12 ) acting on the tool which is axially displaceable within a percussive pin guide ( 11 ). The percussive pin guide ( 11 ) has a body ( 13 ) enclosing the percussive pin ( 12 ). According to the invention, the body ( 13 ) is made from two materials of differing hardness. The invention further relates to an at least percussively-operated hand machine tool, in particular a hammer drill or chisel with a percussion mechanism.
