Value Collection NS06264121 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264121 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, punches, gauges, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 3/8 inches thick, 1/2 inches wide, and 36 inches long, and weighs 1.94 pounds. O1 tool steel is known for its fine grain structure and excellent machinability in the annealed state, making it a reliable choice for fabricating cutting tools, jigs, and fixtures that require hardening after machining. Thickness tolerance is held to plus or minus 0.001 inches, ensuring dimensional consistency for precision work.

This flat stock is suited for machine shops, tool and die operations, and maintenance departments that fabricate their own tooling. It is commonly used to produce punches, dies, blades, drill bushings, and other small precision components that will be oil-hardened after final machining. The 36-inch length provides adequate stock for multiple parts from a single bar, reducing setup time in production environments.

Installation Notes

Machining and heat treatment of O1 tool steel should be performed by qualified machinists or toolmakers familiar with tool steel handling practices. Always machine to final dimensions in the annealed condition before oil hardening. Use appropriate personal protective equipment and follow established shop safety procedures when cutting, grinding, or heat-treating tool steel. Disposal of cutting fluids and quench oils must comply with applicable local environmental regulations.
