Abstract
A rotary angle tool is provided for driving a fastener while controlling the rotational speed of the chuck by varying the pressure or force of the tool against the fastener. The tool includes an angled chuck assembly that is drivable by a motor, an output shaft of the chuck assembly having a rotational axis that is non-parallel to the rotational axis of the motor drive shaft. A sensor is responsive to the proximity of or movement of a detectable element at the chuck output shaft. The sensor generates a signal for controlling the output of the motor in response to detection of the proximity or movement of the detectable element. Moving the chuck output shaft by urging the rotary tool against a fastener varies the proximity of the detectable element relative to the sensor and the sensor output or control proportionally varies the power supplied to the motor.
