Drill Rod Tool Steels 85999019 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999019 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die-making, and precision machining applications. Measuring 0.5 inches thick, 4.5 inches wide, and 18 inches long, this flat stock is produced to close dimensional tolerances: thickness tolerance of +0.010 to 0.015 inches, width tolerance of +0.010 to 0.015 inches, and length tolerance of +0.062 inches. Squareness is held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends. At 11.47 pounds, this is a substantial piece suited for fabricating punches, dies, gauges, and other tooling components requiring high wear resistance after heat treatment.

A2 air-hardening tool steel is a standard choice for toolroom and die shop work where dimensional stability through heat treat is critical. This flat stock is suitable for low-to-medium production dies, cutting tools, and forming tools in both job shop and production environments. It is commonly machined in the annealed condition and then air-hardened to final hardness. Machinists, tool and die makers, and metalworking fabricators are the primary users of this material in commercial and industrial settings.

Installation Notes

Tool and die makers should machine this material in the annealed condition before heat treatment. Air-hardening steels require proper heat treat equipment and controlled cooling - follow the material manufacturer's published heat treat parameters for A2 tool steel. Use appropriate cutting tools and feeds for tool steel when sawing or milling to size. Personal protective equipment including eye protection and gloves is required when handling and machining steel stock.
