Value Collection NS06266761 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06266761 is an O1 oil-hardening tool steel flat stock bar measuring 1-1/4 inches thick, 1-1/2 inches wide, and 36 inches long. Manufactured to AISI Type O1 specifications, this flat stock is used by machinists, toolmakers, and metalworking tradespeople who require a predictable, consistently dimensioned steel bar that responds well to oil-quench hardening. The material arrives in the annealed condition and is ready for machining, grinding, or heat treating. Thickness tolerance is held to plus or minus 0.001 inches, making it well-suited for precision tooling and die work where dimensional accuracy is critical before hardening.

O1 tool steel flat stock of this size is commonly used in job shops, tool-and-die operations, and maintenance machining environments. Typical applications include cutting tools, punches, dies, gauges, and fixtures where moderate toughness and good wear resistance after hardening are required. The 36-inch length provides sufficient stock for multiple blanks to be cut from a single bar, reducing material waste in low-volume production or prototype tooling scenarios.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for precision pre-machined fitment
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• 19.35 pounds per bar — suitable for direct use without additional stock prep in most tooling applications

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat bar suitable for use in standard tool-and-die, punch, gauge, and fixture fabrication applications where AISI O1 material specification is required.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate tooling rated for hardened or pre-hardened steel. The bar should be fully annealed before machining operations and heat treated by a qualified heat-treat technician following AISI O1 hardening and tempering procedures. Eye protection, secure workholding, and proper blade or wheel selection are required when sawing or grinding this material. Do not attempt oil-quench hardening without appropriate furnace equipment and quench facilities.
