Tools 79 Automatic Center Punch, 1/2 In. Tip, 4-7/8 In. L

An automatic center punch is an essential hand tool for anyone who drills, marks, or stakes metal, wood, or other materials. The General Tools Model 79 delivers precise center marks that prevent drill bits from wandering, eliminating the need for a hammer and making one-handed operation fast and effortless. Whether you're a professional machinist, automotive technician, or DIY enthusiast, this versatile punch handles heavy-duty metals while remaining gentle enough for wood and thin-walled tubing.

Accuracy and control matter when starting holes or marking materials for cutting. This automatic center punch prevents drill bit travel by providing accurate center marks. The adjustable spring tension lets you customize the impact force for different materials—heavier strikes for steel and lighter touches for delicate work.

Features and Benefits
