1. A power tool, comprising:
a tool receiving device configured to be moved in rotation about an output axis and hold a tool device on the power tool such that the output axis and a tool rotation axis substantially coincide, the tool receiving device comprising:
at least one driving device having at least one torque transmission region arranged at a distance from the output axis so as to transmit a driving force to the tool device; and
a clamping device that is movable relative to the driving device,
wherein:
the driving device and the clamping device are both configured to reach through a single cutout of the tool device that extends through the entire material thickness of a connection region of the tool device,
the clamping device is movable substantially in a radial direction in relation to the output axis to clamp the tool device, and
when the clamping device is in a release state, the clamping device projects, in an axial direction relative to the output axis, beyond the driving device in a direction oriented away from the power tool.
