Drill Rod Tool Steels 06320402 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 06320402 is a precision-ground A2 air-hardening tool steel flat stock used in toolmaking, die making, and machining applications where dimensional accuracy and consistent hardening response are required. Measuring 5/16 inch thick, 4 inches wide, and 18 inches long, this flat stock ships in an annealed condition ready for machining. Thickness tolerance is held to +0.010 to 0.015 inches, width tolerance to +0.010 to 0.015 inches, and length tolerance to +0.062 inches. A2 tool steel is known for moderate toughness, good wear resistance, and low distortion during air-hardening heat treatment, making it a reliable choice for punches, dies, and gauges.

This flat stock is suited for job shops, tool and die shops, and maintenance departments that fabricate or repair cutting tools, forming dies, jigs, and fixtures. The 18-inch length and 4-inch width provide workable stock for a range of mid-size tooling components. The annealed condition allows conventional machining before hardening. This item is typically purchased by machinists, toolmakers, and die setters working in precision manufacturing environments.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures. Follow the material supplier heat treatment guidelines for austenitizing and air-quench hardening sequences. Always use appropriate personal protective equipment when grinding or cutting tool steel stock. Consult applicable shop safety standards before performing heat treatment operations.
