Value Collection NS06264188 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264188 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, jig fabrication, and precision machining applications. Measuring 3/8 inch thick, 1-1/4 inches wide, and 36 inches long, this flat stock is manufactured to tight tolerances, with a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 to minus 0.000 inches. O1 tool steel is a popular choice for shops that need a readily machinable steel that responds well to oil quench hardening, making it suitable for punches, dies, gauges, and cutting tools where dimensional accuracy in the annealed state matters before heat treatment.

This flat stock is intended for use in machine shops, tool and die shops, and fabrication environments where O1 tool steel is the specified material. It ships in the annealed condition, which allows for machining and grinding prior to hardening. The 36-inch bar length is a standard cut suited to bench work and small-run tooling production. Machinists, tool and die makers, and toolroom technicians are the primary users. The AISI Type O1 oil-hardening specification means the material conforms to established composition and heat-treat response standards used across industrial tooling applications.

Key Features

• Length tolerance of plus 0.500 inches
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Standard 36-inch bar length suitable for toolroom and bench fabrication

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolmaking, die making, and precision fixture fabrication where AISI Type O1 material specification is required.

Installation Notes

This material is typically handled by machinists and tool and die makers using standard metalworking equipment including surface grinders, mills, and lathes. Prior to hardening, all machining and grinding operations should be completed to final dimensions. Oil quench hardening should be performed by qualified personnel following recognized heat treatment procedures and shop safety protocols. Allow material to reach ambient temperature and inspect for warpage before post-heat-treat grinding.
