Abstract
A quick release tool holder assembly including a tool holder defining a circular well, a pair of pads positioned on the tool holder and presenting inboard faces intruding into the well, and a wedge block member movable radially into and out of the well in response to rotation of a hand knob. The associated tool includes a wedge recess sized to receive the wedge tip of the wedge block. The pads are positioned within an angular range of 180.degree. as measured about the central axis of the tool and tool holder and the wedge block is positioned centrally within the remaining 180.degree. as measured around the central axis. The tool may be removed for refinishing or replacement simply by withdrawing the wedge block, moving the tool slightly laterally within the well, and then lifting the tool vertically out the well. The tool may be replaced in the well by repositioning it in the well, moving it laterally against the pads, and moving the wedge block forwardly to insert the wedge tip of the wedge block into the wedge recess in the base of the tool to accurately angularly position the tool within the tool holder.
