Drill Rod Tool Steels 85998995 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998995 is an A2 air-hardening tool steel flat stock cut to 3/8 inch thick, 5/8 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 ground to close tolerances, making it suitable for fabricating punches, dies, gauges, and cutting tools. It is used by machinists, tool-and-die makers, and industrial maintenance professionals who require a reliable, heat-treatable steel in a ready-to-use bar form.

This flat stock is suited for cold-work tooling applications in machine shops, fabrication facilities, and maintenance operations. Its pre-cut 18-inch length and tight thickness tolerances reduce setup time when producing tooling components. The A2 grade offers a good balance of toughness and wear resistance, making it a practical choice for moderate-production tooling where D2 would be excessive and O1 would lack sufficient air-hardening stability.

Key Features

• A2 air-hardening tool steel for dimensional stability during heat treat
• Thickness tolerance of +0.010 to 0.015 inches for close-fit applications
• Width tolerance of +0.010 to 0.015 inches
• Length tolerance of +0.062 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Ready-to-machine flat stock in a single-piece quantity

Compatibility

Designed as a standard A2 tool steel flat stock for general cold-work tooling, die-making, and precision gauge fabrication applications where air-hardening steel in flat bar form is required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with cold-work die steels. Follow the steel manufacturer's published heat-treat schedule for austenitizing temperature and air-quench procedures specific to A2 grade. Grinding operations after hardening should use appropriate coolant to prevent surface burning. Wear appropriate PPE when cutting or grinding tool steel stock.
