    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.

    摘要: The tool holder according to the invention for a chipping hammer has a tool receptacle for receiving a tool and a tool securing device for securing the tool in the tool receptacle. The tool securing device provides a shaft having an eccentrically arranged mandrel and at least one end piece and a bar having at least one eye in which the end piece engages in a form-fitting manner. The tool securing device is pivotable into at least one first position for inserting and removing the tool and into at least one second position for securing the tool. The eye has a non-circular cross-section.
