Drill Rod Tool Steels 85998631 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998631 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers working in job shops and industrial manufacturing environments. This flat stock measures 1.5 inches thick by 1.5 inches wide by 18 inches long and is held to tight dimensional tolerances, making it suitable for precision tooling applications where dimensional consistency is critical. The A2 grade designation indicates an air-hardening, medium-alloy cold-work tool steel known for good wear resistance and dimensional stability during heat treatment. It ships as a single piece at a weight of 11.61 pounds.

A2 air-hardening flat stock is commonly used in the fabrication of dies, punches, gauges, jigs, and cutting tools in both light and heavy industrial settings. The air-hardening characteristic of A2 steel reduces distortion during the hardening process compared to oil- or water-quench grades, making it a practical choice for complex or precisely dimensioned tool components. Machinists and tool and die makers typically source this flat stock for applications requiring a balance of toughness and wear resistance in cold-work tooling.

Installation Notes

Machining, grinding, and heat treatment of tool steel flat stock should be performed by qualified machinists or tool and die makers following established shop safety procedures. Always follow ANSI and applicable safety standards when cutting, grinding, or heat-treating tool steel. Use appropriate personal protective equipment, including eye and face protection, when working with this material. Consult the material data sheet for recommended heat treatment parameters before hardening.
