Starrett 819 Automatic Self-Centering Punch

Starrett's 819 Automatic Center Punch is an indispensable tool around the shop. The tool features a pressure actuated internal trip hammer that lets you use the punch one-handed. Just press firmly, and bam! It's the right tool for the job whenever and wherever you need to start drilled holes accurately. Rotating the cap adjusts impact pressure from light enough for wood to heavy enough for cast iron. This model is perfect for hinge installation - the sleeve around the pin centers the punch in the hinge hole so that you can pre-drill with precision.
