Drill Rod Tool Steels 06340004 A2 Flat Stock 18 in

Product Description

The DRILL ROD TOOL STEELS 06340004 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 0.625 inches thick by 0.625 inches wide by 18 inches long and weighing approximately 1.99 pounds, this bar ships ready for layout, grinding, or machining to final dimensions. A2 tool steel offers excellent dimensional stability during heat treatment, making it a reliable choice for punches, dies, and forming tools that require tight tolerances and predictable hardening response. Machinists, toolmakers, and maintenance shops keep this material on hand for both production and repair work.

This flat stock is suited for fabricating or replacing tooling components in job shops, maintenance departments, and tool-and-die operations. The 18-inch length provides enough material for most short-run tooling projects without requiring a full-bar purchase. The air-hardening A2 grade is commonly specified where oil-hardening grades such as O1 produce unacceptable distortion or where through-hardness at moderate cross-sections is required. Minimum order quantity is one piece.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by a qualified machinist or toolmaker using equipment rated for tool steel work. Follow AISI A2 heat treatment guidelines from the material supplier or a recognized metallurgical reference for austenitizing, quenching, and tempering cycles. Allow the bar to reach ambient temperature before precise layout or measurement. Wear appropriate PPE including safety glasses and gloves when cutting or grinding.
