The General Automatic Center Punch is the standard in automatic center punches. It is tough enough to handle those heavy-duty metals, yet not overbearing when working with aluminum skin, or thin-walled tubing.

Replacment point for General's professional automatic center punch P/N GT79

Spring loaded. Alloy hardened steel tip

Stainless steel automatic center punch.

Used for repetitive punching or riveting action. Adjustable for light or heavy impact. Enlarged plastic handle for impact cushioning.

It's a brilliant idea, connect a prick punch and a center punch to each end of a powerful spring to produce the ultimate hammerless punch. Just place the working end on any surface, pull the striking end straight back and release.
