Abstract: A punch tool for punching orifice that has wall surfaces extending at an angle relative to a generally planar surface of a workpiece. The punch tool of the preferred embodiments is provided with configurations that, at the very least, increase the life of the tool, reduce damages to the workpiece during punching in the formation of the angled orifices.

Abstract: A method of using a tool for punching orifice that has wall surfaces extending at an angle relative to a generally planar surface of a workpiece. The method includes sequentially forming two spaced apart impressions formed in the workpiece between first and second generally planar surfaces spaced apart along a longitudinal axis of the workpiece. The two spaced apart impressions form a first orifice wall surface disposed at an obtuse angle with respect to the generally planar surface facing the tool and a second orifice wall surface disposed at an acute angle with respect to the generally planar surface, and coincidental with the punching process, a retention arrangement that secures the workpiece during the forming of the orifice.
