Starrett Automatic Center Punch

Starrett's Automatic Center Punch is an indispensable tool around the shop. The Center Punch 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.
