Drill Rod Tool Steels 85999290 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999290 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick, 1-1/2 inches wide, and 36 inches long. A2 tool steel is a chromium-molybdenum alloy known for its dimensional stability during heat treatment and its balanced combination of wear resistance and toughness. This flat stock ships in an annealed, pre-hardened condition suitable for machining, and is intended for use by tool and die makers, machinists, and metalworking professionals who require tight-tolerance raw material for tooling, jigs, fixtures, and precision components.

A2 air-hardening flat stock is widely used in tool and die shops, machine shops, and industrial fabrication environments. Its air-hardening characteristic reduces distortion during the hardening process compared to oil- or water-hardening grades, making it a preferred choice for flat tools, punches, dies, gauges, and forming tools where dimensional accuracy after heat treatment is critical. This 36-inch bar length is a standard cut suited to bench and mill operations.

Key Features

• A2 air-hardening tool steel for reduced distortion during heat treat
• Thickness tolerance of plus or minus 0.001 inches for precise stock removal planning
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• UNSPSC Code 31231200 for industrial procurement classification

Compatibility

Designed as a standard A2 tool steel flat stock for use in tool and die, machining, and industrial metalworking applications requiring AISI Type A2 air-hardening material.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate coolant and tooling rated for hardened or semi-hardened steel. When heat treating to final hardness, follow the material manufacturer's published A2 austenitizing and tempering parameters. Always wear appropriate PPE when cutting or grinding tool steel. Verify final dimensions after heat treatment before committing to finish grinding.
