Abstract
A clutch mechanism for use in a rotary power tool having a motor comprises an input member to which torque from the motor is transferred and an output member movable between a first position in which the output member is engaged with the input member for co-rotation therewith, and a second position in which the output member is disengaged from the input member. The clutch mechanism further comprises a biasing member biasing the output member into the first position and an electromagnet which, when energized, moves the output member from the first position to the second position.
