Drill Rod Tool Steels 869047 O1 Flat Stock 1/8x5/16x36 in

Product Description

The DRILL ROD TOOL STEELS 869047 is an O1 oil-hardening tool steel flat bar cut to 1/8 inch thick, 5/16 inch wide, and 36 inches long. O1 is an oil-quench tool steel known for good wear resistance, machinability in the annealed state, and stable hardening response. It is widely used for punches, dies, gauges, blades, and precision tooling components where tight dimensional tolerances and consistent hardness are required. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications where dimensional accuracy directly affects tool performance. Machinists, tool and die makers, and fabricators work with this material daily.

This flat stock is suited for job shop, toolroom, and manufacturing environments requiring small-section O1 tool steel in a ready-to-use bar length. The 36-inch length accommodates multiple blanks from a single piece, reducing waste in short-run tooling and fixture work. Width tolerance is plus 0.005 inches, minus 0.000 inches, and length tolerance is plus 0.5 inches. These tolerances follow standard tool steel flat stock conventions and should be accounted for during layout and machining operations.

Key Features

• Supplied in annealed condition for machining prior to hardening

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolroom and fabrication applications requiring this material specification and cross-section.

Installation Notes

Cutting and machining should be performed in the annealed condition before oil hardening. Use appropriate personal protective equipment and follow shop safety protocols when cutting or grinding tool steel. Heat treatment should be performed by qualified personnel following established procedures for O1 tool steel, including proper preheat, austenitizing, and oil quench steps. Consult material data sheets for full heat treat parameters before processing.
