Patent ID: 8540580

Claim:
A tool for use with a power tool, the tool comprising: an input shaft having a rear portion with a shank configured to be removably coupled to a power tool, and a front portion; an output shaft having a front portion and a rear portion, the rear portion of the output shaft rotatably coupled to the front portion of the input shaft, the front portion of the output shaft configured to be coupled to at least one of a tool bit, a screw, and a nut; a clutch assembly releasably coupling the input shaft to the output shaft, the clutch assembly including (i) at least one recess defined in one of the front portion of the input shaft and the rear portion of the output shaft, (ii) at least one aperture defined in the other of the front portion of the input shaft and the rear portion of the output shaft; (iii) at least one roller received in the at least one aperture; and (iv) a spring that biases the at least one roller radially inwardly into the at least one recess such that torque is transmitted from the input shaft to the output shaft when a predetermined torque threshold is not exceeded, and that enables release of the at least one roller radially outwardly from the at least one recess such that torque is not transmitted from the input shaft to the output shaft when the predetermined torque threshold is exceeded; and a clutch lock out member moveable between a first position and a second position, wherein in the second position the clutch lock out member completely prevents interruption of torque transmission from the input shaft to the output shaft regardless of an amount of input torque.
