A hand held power tool, for delivering a torque to a joint, includes a housing, a motor, an output shaft, and a flywheel which is arranged in bearings with respect to the housing. A selection gear is arranged to selectively connect the motor to either the output shaft, or the flywheel, such that the flywheel may be set to rotate before a tightening operation and wherein the rotation of the flywheel may be used to decrease the counter forces acting on the power tool. |
