When using the Rennsteig Automatic Center Punch, form Anglo American Tools, a machine steel, rugged self-striking mechanism is activated by downward pressure, eliminating the need to strike with a hammer. A precision all-steel design with replaceable hardened pin is used for striking center holes for drilling in layout work. The shank diameter is approximately 9/16". This tool is available in three sizes: 3/4" (No. RN430229), 5" (No. RN430230) and 5-1/4" (No. RN430231). Spare pins are available. These tools have also been updated to feature a protective two-component hand-guard.
