<p>A torque-controlling actuator clutch (240) is used in a tool system with a motor for rotating a bit. The actuator clutch (240) includes a driving shaft (241) rotatingly driven by the motor (220), a driven shaft (242) operatively connected to and rotated by the driving shaft (241), the bit removably attached to the driven shaft (242), a clutch mechanism (243) for selectively coupling and uncoupling the driving shaft and the driven shaft and an actuator (244) operated by a pressure of a working medium for pressing the clutch mechanism (243) into engagement so that a torque can be transferred from the driving shaft (241) to the driven shaft (242). A control unit (300) is used to control the pressure of the working medium supplied to the actuator (244) and the torque transferred from the driving shaft to the driven shaft.</p> |
