Value Collection NS06266746 O1 Tool Steel Flat Stock

Product Description

The Value Collection NS06266746 is an O1 oil-hardening tool steel flat stock bar sized at 1-1/4 inches thick by 1-1/4 inches wide by 36 inches long and weighing 16.13 pounds. Manufactured to AISI Type O1 specifications, this flat stock is commonly machined into dies, punches, gauges, and cutting tools that require a hard, wear-resistant working surface after heat treatment. The material holds tight dimensional tolerances out of stock, with a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 to minus 0.000 inches, making it suitable for precision toolmaking applications where consistent pre-hardened stock dimensions matter before final grinding and heat treat operations.

O1 tool steel flat stock of this size is used in job shops, tool-and-die facilities, and industrial maintenance departments. Typical applications include blanking dies, forming tools, drill jigs, and precision fixtures. The 36-inch length allows a machinist to cut multiple blanks from a single bar, reducing material waste when producing short-run tooling components. This stock is intended for professional machinists, toolmakers, and die makers working in both production and prototype environments.

Key Features

• AISI Type O1 oil-hardening tool steel — hardens by quenching in oil for controlled distortion during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for consistent pre-machined stock dimensions
• Width tolerance of plus 0.005 to minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Single-piece packaging suitable for low-quantity toolroom procurement

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat stock suitable for use in toolmaking, die making, and precision machining applications requiring oil-quench hardenable steel in flat bar form.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment. Heat treatment, including austenitizing and oil quenching, should follow established procedures for AISI O1 tool steel and should be performed by personnel familiar with metallurgical safety requirements. Proper eye protection, gloves, and ventilation are required during grinding and heat treat operations. Consult applicable shop safety standards and material data sheets before processing.
