TECHNOLOGY MACHINE

The invention relates to a power tool (211)， in particular a hand-held power tool， preferably an angle grinder， which has a tool-holding device (213)， which can be rotated about an output axis (A)， wherein said tool-holding device (213) is designed to hold a tool device (11)， in particular an insert tool， on the power tool (211) in such a way that the output axis (A) and a tool axis of rotation (a) substantially coincide， wherein the tool-holding device (213) has at least a driver device (215) and a clamping device (217)， which can be moved relative to the driver device (215)， wherein， in order to transfer a driving force to the tool device (11)， said driver device (215) has at least one torque transfer region (219)， which is arranged at a distance from said output axis (A). According to the invention， the driver device (215) and the clamping device (217) are provided for reaching through a cut-out (17) of the tool device (11)， which cut-out in particular extends through the entire material thickness of the tool device (11)， and to clamp the tool device (11) by means of the clamping device (217)， which can be moved substantially in a direction radial to the output axis (A).
