The invention relates to a power tool, particularly an electrically driven hand power tool, having at least one tool drive shaft (22, 322) for directly or indirectly rotationally driving a tool insert. The insert tool is thereby received in a tool holder (16, 316) releasably, particularly interchangeably, connected to the tool drive shaft (22, 322), and can be driven by at least one drive device (14, 134), and at least one clutch device (44, 44a, 44b, 44c, 45, 344, 345) coupling the at least one drive device (14, 314) to the at least one tool drive shaft (22, 322). The clutch device (44, 44a, 44b, 44c, 45, 344, 345) comprises at least two different limit torques, preferably selectable by the user, wherein means (122', 322') are provided for resetting the clutch device (44, 44a, 44b, 44c, 45, 344, 345) to a lower, preferably the lowest possible, limit torque when the insert tool and/or the tool holder (16, 316) is changed out.
