Drill Rod Tool Steels 85997187 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997187 is an A2 air-hardening tool steel flat stock bar sized at 0.125 inches thick, 0.5 inches wide, and 72 inches long. A2 tool steel offers excellent dimensional stability during heat treatment and good wear resistance, making it a reliable choice for dies, punches, gauges, and general toolmaking applications. At 1.2 pounds per piece, this flat stock is easy to handle on the bench. Machinists, tool-and-die makers, and metalworking professionals will find the controlled tolerances and consistent cross-section suited to precise fabrication work.

This flat stock is used in toolroom and shop-floor applications where air-hardening steel is preferred over oil- or water-hardening grades. Typical uses include die components, forming tools, fixture plates, and cutting blades that require good toughness and moderate wear resistance. The 72-inch length allows for multiple parts to be cut from a single bar, reducing material waste on production runs. This product is appropriate for both custom one-off tooling and short-run production.

Installation Notes

Cutting, grinding, and machining should be performed by qualified machinists or tool-and-die makers using appropriate equipment and personal protective equipment. When heat treating to harden, follow standard AISI A2 air-hardening procedures and use calibrated furnace equipment. Allow the bar to reach a safe handling temperature before finishing operations. Always secure workpieces properly during any cutting or grinding operations.
