Abstract: A dual function device for pressing a workpiece in a single stroke of a press ram comprises a housing that carries first and second tools each having a working end that protrudes from one end of the housing. The housing can be removably attached, at an end opposite the one end, to the press ram. The first tool has a shank portion that includes a piston slidable in a piston chamber formed in the housing. Pressurized liquid may fill the piston chamber to hold the first tool in an extended protruding position with its working end protruding farther from the housing than the working end of the second tool. The device further includes a relief valve that selectively and controllably permits liquid to be exhausted from the piston chamber when the liquid pressure exceeds a predetermined limiting value. Therefore, as the press ram is operated through a single stroke, the first tool first contacts the work piece to perform one function.
