Value Collection NS06264964 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264964 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, jig fabrication, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 0.5 inches thick, 2.5 inches wide, and 36 inches long. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy is critical before and after heat treatment. At 12.89 pounds, this is a solid, full-length bar intended for shop cutting and machining by metalworking professionals and tool and die makers.

O1 tool steel is a general-purpose oil-hardening grade widely used in industrial shops for producing punches, dies, gauges, knives, and cutting tools. This flat stock format is a starting material — machinists and toolmakers cut, mill, grind, and shape it to final form before hardening and tempering. It is appropriate for both low-volume job shop work and production tooling environments. Width tolerance is held to plus 0.005 inches, minus 0.000 inches, and length tolerance is plus 0.5 inches, allowing for finish-cut-to-length operations on a band saw or cold saw.

Key Features

• AISI Type O1 oil-hardening tool steel — standard grade for dies, punches, and precision tooling blanks
• 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 to allow for clean finish cuts
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Full 36-inch length provides flexibility for multiple part blanks from a single bar

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock blank suitable for use in any machine shop, tool room, or die shop requiring AISI Type O1 material in a 0.5 inch by 2.5 inch cross-section.

Installation Notes

This material is handled and processed by machinists and tool and die makers using conventional metal cutting and grinding equipment. Always use appropriate cutting fluid when sawing or milling tool steel to extend tool life and maintain surface integrity. Material should be stress-relieved or annealed before precision machining if residual stress is a concern. Oil-hardening heat treatment should be performed by qualified personnel following established metallurgical procedures for AISI O1 tool steel.
