Abstract:
The invention relates to a power tool, in particular an electrically operable hand-held power tool, having at least one tool drive shaft for direct or indirect rotary drive of an insert bit, with the insert bit being accommodated in a tool holder that is connected or detachably connected to the tool drive shaft, particularly in a replaceable fashion. At least one drive device and at least one clutch device that couples the at least one drive device to the at least one tool drive shaft is provided which has at least two different, user-selectable, limit torques. An actuating device is provided that makes it possible, with a replacement of the insert bit and/or a replacement of the tool holder, to reset the clutch device to a lower limit torque, preferably to the lowest possible limit torque.
