Drill Rod Tool Steels 85999571 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999571 is an A2 air-hardening tool steel flat stock measuring 3/16 inches thick, 5/8 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work alloy known for its dimensional stability during heat treatment, good wear resistance, and moderate toughness. This flat stock is supplied in the annealed condition and is intended for machining into dies, punches, forming tools, and other precision tooling components. Machinists, tool-and-die makers, and industrial fabricators work with this material when consistent cross-section tolerances are required across the length of a blank.

This flat stock is suited for toolroom and production environments where cold-work tooling is fabricated in-house. Typical applications include blanking dies, trimming dies, forming punches, and gauges. The 36-inch length provides a full working blank for most bench-length tooling projects. The tight thickness tolerance of plus or minus 0.001 inches reduces the amount of stock that must be removed during surface grinding, saving setup time on precision tooling projects.

Key Features

• A2 air-hardening tool steel per AISI specification - stable dimensions during heat treat with minimal distortion
• Thickness tolerance of plus or minus 0.001 inches for precision-ground flat stock
• Width tolerance of plus 0.000 to plus 0.005 inches - stock is never undersized in width
• Length tolerance of plus or minus 0.250 to 0.500 inches on the 36-inch nominal length
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Full 36-inch length supports common toolroom blanking and layout requirements

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for fabrication of cold-work dies, punches, gauges, and similar precision tooling components where AISI A2 material is specified.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool-and-die makers using equipment appropriate for hardened or semi-hardened alloy steels. Always anneal or stress-relieve per the material specification before and after rough machining as required. Follow the tool steel manufacturer's recommended heat treatment cycle for hardening and tempering A2 material. Use appropriate personal protective equipment when cutting or grinding any tool steel stock.
