Drill Rod Tool Steels 86220050 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86220050 is an A2 air-hardening tool steel flat stock bar measuring 5/16 inches thick, 1/2 inch wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock is precision-ground to tight tolerances, including a thickness tolerance of plus or minus 0.001 inches and a square tolerance of plus or minus 0.003 inches. It is used by tool and die makers, machinists, and metalworking professionals who need a reliable blank for tooling, punches, dies, and fixtures.

A2 air-hardening flat stock is a standard material in tool and die shops, job shops, and maintenance departments. The 18-inch length and 5/16 by 1/2 inch cross-section make this bar well-suited for cutting into blanks for small punches, form tools, jig components, and precision fixtures. The air-hardening characteristic of A2 steel reduces distortion during hardening compared to oil- or water-quench grades, making it a practical choice for close-tolerance tooling applications.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers using appropriate equipment. Follow established metallurgical procedures for hardening and tempering A2 tool steel, including proper soak times and temper cycles. Always wear appropriate personal protective equipment when cutting or grinding tool steel. Allow material to reach room temperature before taking final measurements after thermal operations.
