Abstract
A device for a drilling hammer and/or percussive hammer has a tool holding fixture for holding a tool and for transmitting a torque to the tool. A component of the tool holding fixture consists of a hollow cylindrical tool holder, which has an insertion opening for an insertion end of the tool, and has an impact opening, via which a percussive action can be applied to the insertion end. A stopping surface, which is stationary with regard to the tool holder and which acts in an axial direction of the tool holder, is provided in the tool holder in the area of the impact opening. The tool holding fixture is particularly suited for insertion ends according to the SDS-max standard.
