Abstract
An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a hub rotatably supported within the housing between the arms and configured to be coupled to the spindle to receive torque therefrom, a ball detent disposed within the hub and selectively engagable with the spindle to axially lock the accessory to the power tool, a sleeve axially slidable along the arms and relative to the hub between a first position in which the sleeve biases the ball detent radially inward and into engagement with the spindle when coupled to the hub to axially secure the accessory to the tool, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the tool, and a second mating member axially fixed to the arms of the housing, wherein the sleeve is slidable between the second mating member and the body of the housing, and wherein the first and second mating members are engaged when the accessory is axially secured to the tool to rotationally fix the accessory to the tool.
