Drill Rod Tool Steels 85997658 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997658 is an A2 air-hardening tool steel flat stock bar intended for toolmaking, die work, punches, gauges, and precision machined components that require consistent dimensional control. It measures 0.5 inches thick, 1.25 inches wide, and 72 inches long, with a weight of 12.9 pounds. A2 tool steel offers good toughness and wear resistance with minimal distortion during air-hardening heat treatment, making it a reliable choice for applications where dimensional stability after hardening is critical. Machinists, tool-and-die makers, and metal fabricators work with this material in job shops and production environments.

This flat stock is suited for fabricating cutting tools, forming dies, jigs, fixtures, and wear plates in both job shop and production settings. The 72-inch length allows for multiple part blanks to be cut from a single bar, reducing material waste. The tight thickness tolerance of plus or minus 0.001 inches supports applications where close fits are required before and after heat treatment. This product ships as a single bar per package.

• Squareness tolerance of 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-bar packaging with a minimum order quantity of 1

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications where A2 grade material is specified.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool-and-die makers using appropriate metalworking equipment. Follow the material manufacturer's published heat treatment guidelines for A2 tool steel when hardening and tempering. Always wear appropriate PPE when cutting or grinding tool steel. Verify final dimensions after any heat treatment cycle, as minor distortion can occur even with air-hardening grades.
