Drill Rod Tool Steels 85998763 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998763 is an A2 air-hardening tool steel flat stock bar cut to a finished size of 0.125 inches thick, 0.375 inches wide, and 18 inches long. A2 tool steel offers good toughness and wear resistance with minimal distortion during air hardening, making it a reliable choice for dies, punches, gauges, and precision tooling components. This flat stock is supplied in an annealed condition ready for machining, then hardened by the end user. Machinists, tool and die makers, and industrial maintenance shops are the primary users of this material. The piece weighs approximately 0.27 pounds.

This flat stock is suited for fabrication of cutting tools, forming dies, blanking dies, trim dies, and general toolroom applications where dimensional stability after heat treatment is critical. The 18-inch length allows for single-piece tooling blanks or multiple shorter components cut from one bar. Its air-hardening characteristic reduces quench cracking risk compared to oil-hardening grades, making it a preferred grade in precision tool shops handling complex cross-section components.

Installation Notes

Machining and grinding should be performed in the annealed state before hardening. Heat treatment, including austenitizing temperature, soak time, and air quench procedure, should follow the material manufacturer recommendations for A2 tool steel and applicable shop standards. Always use appropriate personal protective equipment when cutting, grinding, or heat treating tool steel. Secure workpieces properly during machining to maintain dimensional accuracy within the stated tolerances.
