Drill Rod Tool Steels 85999308 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999308 is an A2 air-hardening tool steel flat stock bar measuring 3/32 inches thick, 2 inches wide, and 36 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 held to tight tolerances: plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus or minus 0.250 to 0.500 inches on length. It is used by tool and die makers, machinists, and fabricators working in job shops, maintenance operations, and production environments.

This flat bar is suited for applications requiring precise stock material that will be further machined, ground, or heat-treated. Typical uses include punches, dies, jigs, fixtures, gauges, and wear components. The A2 air-hardening grade is commonly selected when distortion control during hardening is a priority. The 36-inch length and 2-inch width make it practical for benchtop layout and cutting operations without additional breakdown.

Key Features

• A2 air-hardening tool steel for low distortion during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for precise stock removal planning
• Width tolerance of plus 0.000 to 0.005 inches for close-fit applications
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• AISI Type A2 material specification for consistent alloy chemistry
• Ready-to-machine flat stock format in a single 36-inch length

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat bar suitable for cold-work tooling, die-making, and general precision machining applications where dimensional stability after heat treatment is required.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate tooling rated for hardened or semi-hardened steel. Secure the workpiece firmly before any cutting operation. Heat treatment of A2 tool steel should follow the alloy manufacturer's published hardening and tempering cycle; improper heat treatment can result in cracking or inadequate hardness. Eye protection and appropriate PPE are required when cutting or grinding.
