Drill Rod Tool Steels 85999266 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999266 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick by 3/4 inches wide by 36 inches long. A2 tool steel is an air-hardening, cold-work alloy known for its dimensional stability during heat treatment and its balanced combination of wear resistance and toughness. This flat stock ships in the annealed condition, ready for machining, grinding, and subsequent hardening by the end user. It is used by toolmakers, machinists, die makers, and maintenance technicians who require tight-tolerance steel stock for fabricating punches, dies, gauges, blades, and similar tooling components.

This flat stock is suited for job shops, tool rooms, and maintenance departments in both light and heavy manufacturing environments. Its A2 air-hardening designation makes it appropriate for applications where oil-hardening steels would introduce unacceptable distortion risk. Typical uses include cutting tools, forming dies, shear blades, and precision fixtures where consistent cross-section dimensions and controlled tolerances are critical to finished-part accuracy.

Key Features

• AISI A2 air-hardening cold-work tool steel for minimal distortion during heat treat
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations
• Width tolerance of plus 0.000 to plus 0.005 inches for predictable fit in tool slots and fixtures
• Length tolerance of plus or minus 0.250 to 0.500 inches - cut-to-length bar format
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-piece minimum order quantity suits small-quantity toolroom procurement

Compatibility

Designed as a standard AISI A2 air-hardening flat tool steel bar compatible with conventional toolroom machining, grinding, EDM, and heat-treat processes that accept A2 grade cold-work tool steel.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers following established shop procedures. Always use appropriate personal protective equipment when machining or grinding tool steel. Heat treatment - including hardening and tempering - must follow verified time and temperature cycles for AISI A2 steel; consult the steel supplier's published data sheet for guidance. Deburr all cut edges before handling to prevent injury.
