Drill Rod Tool Steels 86220159 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86220159 is an A2 air-hardening tool steel flat stock bar cut to 5/16 inches thick, 1-1/2 inches wide, and 18 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 precision-ground to tight tolerances, making it well-suited for fabricating dies, punches, gauges, and custom tooling components. Machinists, toolmakers, and industrial maintenance technicians work with this material in job shops, tool-and-die operations, and maintenance facilities where consistent stock dimensions are critical to finished-part accuracy.

This flat stock is used in cold-work tooling applications where moderate toughness and good hardenability are required. Typical uses include blanking dies, forming dies, trim dies, and precision fixture components. The 18-inch length provides a practical working blank for most bench and machine operations. The bar ships in a single-piece quantity, making it straightforward to order for individual tooling projects or prototype work.

Installation Notes

This is raw material stock intended for machining, grinding, and heat treatment by qualified toolmakers or machinists. Follow standard tool steel handling practices: secure the bar properly during sawing or milling operations, and use appropriate cutting fluids for tool steel. Heat treatment should be performed by a qualified heat treater following AISI A2 specifications for austenitizing, air quenching, and tempering. Always wear appropriate PPE when machining tool steel.
