Part holding press tool with non-magnetic part holding mechanism
 A workpiece holding press tool with an elongated body having an annular collar extending from an end face and a plug member secured to the collar by a fastener. The plug forms an annular groove with the body that receives a retainer clip which frictionally engages the inside surface of a workpiece to retain the workpiece on the press tool. The retainer clip is a circular spring steel wire having opposed ends with a relieved portion formed on the outside surface thereof to prevent scratching, marring or otherwise damaging the inside surface of the workpiece. In another embodiment, a second plug is added to provide a second annular groove to receive a second retainer clip for holding elongated workpieces having a cylindrical inside diameter.
