<p>A hand-held power tool has a tool body (103), a motor (111) housed in the tool body (103) and a grip part (109) designed to be held by a user, and performs a predetermined operation on a workpiece by a tool bit (119) rotationally driven by the motor (111). The power tool includes a clutch (134) that transmits torque and interrupts torque transmission between the motor (111) and the tool bit (119), a non-contact torque sensor (151) that detects torque acting on the tool bit (119) in non-contact with a rotation axis (149) rotating together with the tool bit (119), and a clutch control system (157) that controls coupling and decoupling of the clutch (134) according to a torque value detected by the non-contact torque sensor (151).</p> |
