Drill Rod Tool Steels 85997575 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997575 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. It measures 0.375 inches thick by 0.5 inches wide by 72 inches long and ships at 3.88 pounds. A2 tool steel is an air-hardening, cold-work alloy known for its dimensional stability during heat treatment and good wear resistance. This flat stock is ground to close tolerances, making it suitable for fabricating punches, dies, gauges, and similar precision tooling components. Machinists and toolmakers work with this material in both job shop and production environments.

This flat stock is used in cold-work tooling applications where dimensional accuracy and post-heat-treat stability are priorities. Typical uses include punch and die sets, form tools, blanking tools, and precision fixtures. The 72-inch bar length provides flexibility for cutting multiple blanks from a single piece. The close width and thickness tolerances reduce the amount of stock removal needed before final finishing or heat treatment.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate coolant and tooling rated for hardened or semi-hardened steel. Heat treatment of A2 tool steel should follow established metallurgical procedures and is typically performed by a qualified heat treater. Always wear appropriate PPE when cutting or grinding tool steel bar stock. Handle long bar stock carefully to prevent bending or edge damage during storage and transport.
