Value Collection NS06124127 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06124127 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, punches, and precision machining applications. Manufactured to AISI Type O1 material specification, this flat stock measures 0.375 inches thick, 1.25 inches wide, and 18 inches long, with a package weight of 2.42 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications that demand tight dimensional control. Width tolerance is plus 0.005 inches, minus 0.000 inches, and length tolerance is plus 0.25 inches. O1 tool steel offers good machinability in the annealed state and responds well to oil-quench hardening heat treatment.

This flat stock is used in machine shops, toolrooms, and fabrication environments. Typical applications include blanks for punches, dies, blades, gauges, and cutting tools. It is sized for bench or surface grinder work where a close-tolerance starting blank is needed. Machinists and tool-and-die makers work this material in its annealed condition before hardening and tempering to final service hardness. The 18-inch length provides workable stock for most short-run tooling projects without excessive material waste.

Installation Notes

Machining and grinding of O1 tool steel should be performed in the annealed condition prior to hardening. Heat treatment, including austenitizing, oil quenching, and tempering, should be carried out by qualified personnel following established metallurgical procedures for AISI O1. Always use appropriate cutting fluids and personal protective equipment when machining tool steel. Dispose of grinding swarf and cutting fluids in accordance with local regulations.
