Drill Rod Tool Steels 817371P O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 817371P is a precision-ground O1 oil-hardening tool steel flat stock used in toolmaking, die making, and general machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 0.5 inches thick, 1.5 inches wide, and 18 inches long, with a shipping weight of 3.83 pounds. O1 tool steel is widely used for its good machinability in the annealed state and its ability to achieve high hardness after oil quenching. Thickness tolerance runs +0.010 to +0.015 inches, width tolerance runs +0.010 to +0.015 inches, and length tolerance is +0.25 inches. Licensed machinists, tool and die makers, and metalworking shops are the primary users of this material.

This flat stock is suited for fabricating punches, dies, gauges, cutting tools, and fixtures in job shop and production toolmaking environments. The 18-inch length allows for multiple blanks to be cut from a single piece, reducing material waste. Its annealed condition makes it ready for machining prior to heat treatment. The O1 grade performs well in applications where moderate toughness and good wear resistance are required after hardening.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified machinists or tool and die makers familiar with O1 oil-hardening procedures. Material should be handled with appropriate lifting and cutting equipment given its density. Always follow established shop safety practices when sawing, milling, or grinding tool steel stock. Heat treatment, including annealing and oil quenching, should be performed according to the material specification to achieve the desired hardness and avoid cracking.
