Apex 82270 Center Punch 3/8 X 5 Inch Alloy Steel

Product Description

The APEX 82270 is a center punch designed for marking centerlines and pilot drill locations on metal workpieces. Built from alloy steel with a precision-hardened work end, the punch delivers enough hardness to pierce metal surfaces cleanly while the striking end is softened to reduce the risk of chipping under hammer blows. The hex stock profile seats securely in a grip or holder for controlled, repeatable use. At 5 inches long with a 3/8-inch diameter, this punch suits the demands of professional metalworkers, machinists, pipefitters, and fabricators who need accurate layout tools on the job or in the shop.

This center punch is suited for layout and layout-prep work in fabrication shops, mechanical rooms, and field installations where accurate pilot locations are required before drilling. The 3/8-inch hex stock is compatible with standard punch holders and grips, making it straightforward to integrate into an existing tool kit. The ground surface finish and laser-etched size identification marks support fast tool selection in high-volume environments where multiple punch sizes are in regular use.

Key Features

• Precision-hardened work end for reliable metal-piercing performance

Compatibility

Installation Notes

Center punches are typically used by machinists, fabricators, and trade professionals performing layout work prior to drilling. Place the hardened tip on the marked location and strike the softened end with a ball-peen or machinist hammer — do not use a sledge or oversized striking tool. Inspect the tip periodically for deformation and replace the punch if the work end shows cracking or mushrooming.
