Drill Rod Tool Steels 57969 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57969 is an O1 oil-hardening tool steel flat stock bar intended for toolmaking, die work, punches, gauges, and precision machined components requiring tight dimensional tolerances. Conforming to AISI Type O1 specification, this flat stock measures 9/16 inches thick, 2 inches wide, and 36 inches long, with a weight of 11.61 pounds per piece. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy before heat treatment is critical. Licensed machinists and tool and die makers are the primary installers and users of this material.

This flat stock is used in tool and die shops, machine shops, and maintenance departments requiring a reliable pre-cut O1 tool steel bar. O1 grade is a general-purpose oil-hardening steel well suited for short-run tooling, blanking dies, forming tools, bushings, and fixtures. The 36-inch length allows for multiple blanks to be cut from a single bar, reducing material waste in typical shop environments. This product ships as a single piece with a minimum order quantity of one.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metal-cutting equipment. Wear appropriate personal protective equipment when cutting, grinding, or machining. Heat treatment, including oil quenching, should follow established AISI O1 hardening procedures and be performed by personnel trained in tool steel metallurgy. Handle bar stock with care to avoid nicking or scoring precision-ground surfaces prior to machining.
