Drill Rod Tool Steels 03720232 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720232 is an A2 air-hardening tool steel flat stock bar measuring 7/8 inch thick, 2-1/2 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 supplied in the annealed condition, ready for machining, grinding, and subsequent heat treatment. It is used by tool and die makers, machinists, and metalworking shops that require a reliable, consistent-tolerance steel bar for fabrication of dies, punches, gauges, and similar tooling components. At 22.98 pounds per piece, it is a substantial bar suited for demanding tooling applications.

A2 air-hardening flat stock is a standard material choice in tool and die shops, mold-making facilities, and precision machining environments. It is well suited for applications where distortion-free hardening is critical, such as blanking dies, forming dies, trim dies, and cutting tools. The 36-inch length provides flexibility for cutting multiple blanks from a single piece. Tolerances are held to tight commercial standards, making this stock appropriate for direct machining without requiring significant cleanup of the milled surfaces.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with cold-work die steel processing. Always follow the material manufacturer's recommended preheat, austenitizing, and air-quench procedures for A2 steel to achieve target hardness without cracking. Use appropriate personal protective equipment when cutting, grinding, or machining steel bar stock. Consult applicable shop safety standards before beginning any cutting or heat-treat operations.
