Value Collection NS06266787 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06266787 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, punches, gauges, and precision machined components. Manufactured to AISI Type O1 material specification, this flat stock measures 1-1/4 inches thick, 2 inches wide, and 36 inches long, with a weight of 25.79 pounds. Thickness tolerance is held to +/- 0.001 inches, making it suitable for applications where dimensional accuracy is critical before and after heat treatment. Machinists and tool and die makers select O1 flat stock for its consistent pre-hardened properties and predictable response to oil-quench hardening.

This flat stock is suited for job shop, tool room, and light manufacturing environments where custom tooling, fixture components, jigs, and wear parts are fabricated in-house. The 36-inch length provides sufficient stock for multiple part blanks from a single piece. Width tolerance is held to +0.005 / -0.000 inches and length tolerance is +0.5 inches, allowing for standard saw-cut or shear-cut ends. Squareness is specified at 0.003 inches on edges and 0.004 inches per inch of thickness on ends, consistent with standard mill-finish tool steel flat stock.

Compatibility

Designed as a standard mill-form O1 oil-hardening tool steel flat bar suitable for tool room and die shop applications requiring AISI Type O1 material specification.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by a qualified machinist using appropriate metalworking equipment and personal protective equipment. Oil-hardening heat treatment should be carried out by a trained heat treat technician following established procedures for AISI O1 tool steel. Allow the bar to reach a uniform temperature before quenching, and handle hot stock only with proper tooling. Verify final dimensions after any heat treat operation, as distortion can occur.
