Value Collection NS06265763 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06265763 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a ready-to-machine blank with tight dimensional tolerances. Manufactured to AISI Type O1 specification, this flat stock measures 0.75 inches thick, 1.25 inches wide, and 36 inches long, and weighs 9.68 pounds. O1 tool steel offers excellent machinability in the annealed state and responds predictably to oil-quench hardening, making it a reliable choice for punches, dies, gauges, and cutting tools that require a hard, wear-resistant surface after heat treatment.

This flat stock is suited for job shops, tool and die facilities, and maintenance departments that fabricate or replace tooling in-house. The 36-inch length provides enough material to yield multiple blanks from a single bar when cutting to finished part dimensions. Its annealed condition allows conventional milling, drilling, and grinding before hardening. The bar is appropriate for both light-production tooling and one-off prototype applications where dimensional accuracy from the mill is critical before any secondary machining operations begin.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for tight dimensional control
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Annealed condition supports conventional machining prior to hardening

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar suitable for general toolmaking, die making, and gauge fabrication applications requiring AISI Type O1 material specification.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate coolant and tooling rated for tool steel. Follow established shop safety practices when sawing, grinding, or milling. Heat treatment, including oil quenching and tempering, should be performed according to AISI O1 guidelines by personnel familiar with tool steel hardening procedures. Always allow the bar to fully normalize before finish grinding to final dimensions.
