Value Collection NS06266423 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06266423 is an O1 oil-hardening tool steel flat stock bar intended for toolmaking, die making, punches, gauges, and precision machining applications. Manufactured to AISI Type O1 specifications, this flat stock measures 1 inch thick, 4 inches wide, and 36 inches long, with a weight of 41.25 pounds. Thickness tolerance is held to plus or minus 0.001 inches, ensuring dimensional consistency for close-tolerance work. The controlled tolerances on all three axes make this stock well-suited for applications where fit and finish are critical before heat treatment.

This O1 tool steel flat stock is used in machine shops, toolrooms, and fabrication environments where a readily machinable, oil-hardening steel is required. O1 is a general-purpose tool steel that machines well in the annealed condition and achieves high hardness after oil-quench heat treatment. Typical applications include blanking dies, forming tools, cutting tools, jigs, and fixtures. It is appropriate for both small-shop and production toolroom use where a reliable, predictable tool steel is needed prior to hardening and grinding.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate personal protective equipment and cutting tools rated for steel. Material should be in the annealed condition for machining prior to any heat treatment cycle. Heat treatment, including oil quenching, should follow established metallurgical procedures and applicable shop safety protocols. Secure the workpiece properly during all cutting and grinding operations to prevent movement and injury.
