Drill Rod Tool Steels 57882 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57882 is an O1 oil-hardening tool steel flat stock bar sized at 0.125 inches thick, 6 inches wide, and 36 inches long. Conforming to AISI Type O1 material specification, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 inches to 0.000 inches. At 7.13 pounds, it provides substantial stock material for precision machining, toolmaking, and die work. Licensed machinists, tool and die makers, and metalworking shops are the primary users of this material.

O1 oil-hardening tool steel flat stock is commonly used in the fabrication of punches, dies, gauges, knives, and cutting tools where dimensional accuracy and hardening capability are critical. This 36-inch length allows for single-piece or multiple-part blanks to be cut from a single bar, reducing scrap and setup time in production and job shop environments. It is suited to applications requiring a ground or precision-milled flat stock starting material prior to heat treatment.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment. Follow established shop safety practices including eye protection and secure workholding when sawing or milling. Heat treatment should be performed by a qualified heat treater familiar with O1 oil-hardening procedures. Handle bar stock carefully to avoid surface damage that could affect dimensional tolerances.
