Automatic Center Punch Operation

The General Tools 70079 is a spring-loaded hand tool that creates a starter dimple without a hammer. Squeezing the handle stores energy and releases it in a single controlled strike on the workpiece.

General Metal Marking Tasks

Suited for machinists, fabricators and DIY users who need quick, repeatable centre marks before drilling. Not suited for buyers who need adjustable impact force or a complete punch and chisel set for heavier layout work.

Spring-Loaded Impact Mechanism

The internal spring delivers automatic impact when the handle is pressed, removing the need for a separate striking tool. This mechanism decides whether the punch fits the user's preferred marking workflow.
