A hand-held power tool includes a motor mounted in a housing, with a two-axis universal joint mounted to the housing and supporting a rotary chuck. The universal joint includes a yoke mounted to the housing and a hub mounted to the yoke, the hub supporting the chuck. First and second clutches are provided for locking the yoke and the hub. A locking mechanism operatively connects the first and second clutches, and releases both of the first and second clutches simultaneously. A quick release chuck includes a spindle having a longitudinal bore for accepting a shank. A ball or like engaging device is disposed in a radial bore, extending into the longitudinal bore, and radially movable so that at least a portion of the ball extends radially into the longitudinal bore to engage a recess in the shank. A spring biased outer collar disposed about the spindle is movable longitudinally relative to the spindle and has a tapered face for forcing the ball into an aperture. A spring biases the collar into a locking position.
