The Self-Centering Punch Set is handy and versatile. Features a threaded handle with self-centering pointed plunger. The handle will accommodate nine interchangeable threaded cutting tubes. Can cut through leather, rubber, paper, plastics, and other soft materials. The self-centering point makes these punches ideal for cutting concentric washers in small quantities by hand. All cutting edges are properly hardened. Comes in a sturdy plastic box for storage.
Use punches on a wood or plastic cutting block or the C.S. Osborne # 603 Cutting Pad. To apply pressure, use of a C.S. Osborne wooden or rawhide mallet, or rawhide maul is recommended. Not recommended for use with a steel hammer.Tube Sizes in Punch Set - 1/4", 5/16", 3/8", 7/16", 1/2", 5/8", 3/4", 7/8", and 1"
