Value Collection NS06264949 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264949 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die-making, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 0.5 inches thick, 2 inches wide, and 36 inches long, weighing 10.32 pounds. O1 tool steel is a versatile oil-hardening grade known for its good dimensional stability during heat treatment and its ability to hold a sharp edge after hardening. Machinists, tool and die makers, and metalworking shops use this stock to fabricate punches, dies, gauges, and cutting tools requiring consistent geometry and reliable hardenability.

This flat stock is suited for job shops, tool rooms, and production environments where precision-ground or saw-cut blanks are needed as starting material. The controlled tolerances make it appropriate for applications where near-net-shape stock reduces pre-machining time. It ships as a single bar per package and is intended for professional metalworking use where AISI O1 oil-hardening properties are specified by print or process requirement.

Key Features

• 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
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Single bar per package, minimum order quantity of 1

Compatibility

Designed as a general-purpose O1 oil-hardening flat stock blank compatible with standard tool and die fabrication processes requiring AISI Type O1 material specification.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers using appropriate personal protective equipment. Follow established shop protocols and applicable safety standards when sawing, milling, or surface grinding O1 stock. Heat treatment including annealing, hardening, and tempering must follow AISI O1 specifications to achieve desired hardness and avoid cracking. Avoid quenching in water; O1 is an oil-hardening grade and requires an appropriate quench medium.
