Abstract

The invention relates to a machine tool with a tool receiving device that is movable around an output shaft. The tool receiving device is designed to hold a tool device on the machine tool such that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. To transmit a driving force to the tool device, the torque transmission region has at least two output area regions arranged at a distance from said output shaft, with each having a multiplicity of surface points. The tangent planes to said surface points are inclined in regard to an axial plane including said output shaft. The tangent planes are inclined in regard to a radial plane extending perpendicularly to the output shaft. The machine tool thus transmits the output torque to the tool device via the tool receiving device.
