5 Inch Automatic Centre Punch Tool

This five-inch spring-loaded centre punch delivers a hardened steel tip that marks drill points or breaks glass without a hammer. The automatic mechanism stores energy in an internal spring and releases it with a single press, giving repeatable impact force for workshop layout tasks or emergency vehicle egress. Its compact length fits a tool belt pouch or glove compartment.

Spring-Loaded Operation Frees Both Hands

The self-acting design removes the need for a separate striker, letting the user hold the workpiece with one hand and trigger the punch with the other. High-speed steel construction resists tip deformation on hard metals, while the knurled body provides grip in oily or wet conditions. No external power source or consumable cartridges are required.
