Drill Rod Tool Steels 66727 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 66727 is an O1 oil-hardening tool steel flat stock sized at 3/32 inches thick, 1-1/2 inches wide, and 18 inches long. Conforming to AISI Type O1 specifications, this flat bar is manufactured from tool steel and held to tight dimensional tolerances, making it suitable for precision toolmaking, die making, jig fabrication, and general machine shop work. At 0.73 pounds per piece, it is a manageable single-piece stock length. Machinists, toolmakers, and die makers working in job shops, maintenance departments, or production facilities are the primary users of this material.

O1 tool steel flat stock in this size is commonly used for making punches, dies, cutting tools, gauges, and small fixtures where moderate toughness and good wear resistance after oil hardening are required. The 18-inch length provides a practical starting blank for most bench-scale toolmaking operations. This stock is supplied in the annealed condition, ready for machining prior to heat treatment.

Installation Notes

This material is supplied in the annealed condition and should be machined to final dimensions before heat treatment. Oil hardening should be performed by a qualified heat treater following established procedures for AISI O1 tool steel. Always use appropriate personal protective equipment when cutting, grinding, or machining tool steel stock. Follow shop safety standards and consult the material data sheet for heat treatment parameters before processing.
