A method and die assembly for forging a rolling mill coupling, the body of which has a socket in one end and tangs extending from the other end. The assembly comprises bottom and top punches which extrude metal downwardly from the bottom portion of a workpiece and upwardly from the top portion to form walls defining the socket at one end of the workpiece and tangs extending from the other end.
