Drill Rod Tool Steels 03718129 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718129 is an A2 air-hardening tool steel flat stock bar measuring 0.25 inches thick, 0.75 inches wide, and 36 inches long. A2 tool steel is a versatile cold-work die steel known for its balanced combination of wear resistance and toughness after air hardening. This flat stock is held to tight dimensional tolerances, including plus or minus 0.001 inches on thickness and plus or minus 0.003 inches on squareness, making it suitable for toolmaking, die work, and precision machining applications. Machinists, tool and die makers, and metalworking professionals are the primary users of this material.

This flat stock is used in tool and die shops, maintenance and repair operations, and fabrication environments where dimensional accuracy is critical before and after heat treatment. A2 tool steel responds well to air hardening, reducing the risk of distortion compared to oil- or water-hardening grades. It is well suited for punches, dies, forming tools, gauges, and similar components that require a consistent cross-section and predictable heat-treat response. The 36-inch length provides usable stock for a range of small to medium tooling projects.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treatment
• Thickness held to plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to plus 0.005 inches for controlled oversizing
• Squareness tolerance of plus or minus 0.003 inches across the cross-section
• Length tolerance of plus or minus 0.250 to 0.500 inches on the 36-inch bar
• Ready-to-machine flat stock format for toolmaking and die applications

Compatibility

Designed as a standard A2 tool steel flat stock suitable for general cold-work tooling, die making, and precision machining applications where AISI A2 material specification is required.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed with appropriate personal protective equipment and tooling rated for hardened or semi-hardened steel. Heat treatment should be performed by qualified personnel following established procedures for AISI A2 steel, including proper austenitizing temperature ranges and controlled air cooling. Avoid contact with water or oil quench media during hardening unless the process has been specifically adapted. Verify final dimensions after any heat treatment cycle before use in precision tooling applications.
