Drill Rod Tool Steels 02630978 A2 Flat Stock 7/32x2.5x36in

Product Description

The DRILL ROD TOOL STEELS 02630978 is an AISI A2 air-hardening tool steel flat bar cut to 7/32 inch thick by 2-1/2 inches wide by 36 inches long. A2 tool steel offers good dimensional stability during heat treatment and resists deformation after hardening, making it a reliable choice for dies, punches, gauges, and precision tooling. The bar ships at 5.64 pounds. Thickness tolerance is held to plus or minus 0.001 inch, giving toolmakers consistent stock for close-tolerance work. This is a single-piece quantity intended for use in machine shops, tool-and-die operations, and fabrication environments where controlled distortion during hardening is required.

A2 air-hardening flat stock at this cross-section is commonly used for blanking dies, forming tools, cutting blades, and fixture components. The 36-inch length provides flexibility for multiple parts from a single bar. The air-hardening process reduces the risk of quench cracking versus oil- or water-hardened grades, making A2 a practical choice for complex or thin cross-section tooling. This stock is suited for skilled machinists and toolmakers working in job shops, production tooling departments, or maintenance and repair operations.

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat bar for use in dies, punches, gauges, and general tooling applications where controlled distortion and good wear resistance are required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with air-hardening grades. Always follow the material manufacturer's recommended preheat, austenitizing, and tempering cycles for A2 steel before placing hardened components into service. Ensure proper personal protective equipment is used during machining, grinding, and heat-treat operations. Consult applicable shop safety standards and heat-treat specifications before processing this material.
