Abstract: A tool is provided having a drive member and a tool attachment of a push-button release snap-on type releasably secured in the drive member of the tool. The tool includes a camming surface and a recess on one of the drive and tool attachment members, and a resiliently biased locking detent on the other of the members. Upon being disengaged from a normal operating position in the recess, the detent engages and cooperates with the camming surface to positively and automatically eject the attachment from the drive member.

Abstract: The disclosed method features an automatic high production cold working process of forming socket wrenches from coiled alloy steel wire stock. The wire is cut to length, its ends are squared to form a workpiece blank which is then located in a die station and a recess of circular cross-section is cold formed at one end of the workpiece by impacting a round punch into the workpiece which thereafter is transferred to and inserted into a downstream die in a longitudinally reversed orientation whereupon a second punch forms a square socket on an end of the workpiece opposite the end wherein the circular recess is formed. Additional steps of the process include extruding an end of the workpiece surrounding the circular recess to reduce its outside diameter, broaching a hex socket into the necked-down end of the workpiece and piercing an axial through-hole between sockets at opposite ends of the workpiece.
