Drill Rod Tool Steels 869025 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 869025 is an O1 oil-hardening tool steel flat stock bar measuring 3/32 inches thick, 3/8 inches wide, and 36 inches long. AISI Type O1 is a general-purpose tool steel valued for its ease of hardening in oil quench and its ability to hold a sharp edge after heat treatment. This flat stock is suited for machining, grinding, and fabricating cutting tools, jigs, fixtures, punches, and dies. Machinists, toolmakers, and metalworking shops rely on this material in the annealed condition for stock removal, then heat treat to working hardness. Thickness tolerance is held to plus or minus 0.001 inches for close-tolerance tooling work.

This flat stock is used in tool and die shops, machine shops, and industrial fabrication environments. Typical applications include blanks for punches, blades, scraper tools, and small dies where dimensional accuracy in the annealed state is required before finish grinding and hardening. The 36-inch length provides sufficient stock for multiple parts from a single piece. Width tolerance is plus 0.005 inches, minus 0.000 inches, and length tolerance is plus 0.5 inches.

Installation Notes

This material is supplied in the annealed condition and must be heat treated by a qualified machinist or tool and die maker to achieve working hardness. Follow established AISI O1 heat treatment procedures for hardening and tempering, including proper oil quench protocol. Use appropriate personal protective equipment and ventilation during any grinding, machining, or heat treatment operations. Consult applicable shop safety standards before cutting or hardening.
