Value Collection NS06265383 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06265383 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, punches, and general precision machining applications. Measuring 0.625 inches thick by 0.625 inches wide by 36 inches long, this flat stock is cut to close tolerances and ships ready for heat treatment. O1 tool steel is an oil-hardening grade known for its good wear resistance, dimensional stability during hardening, and ease of machining in the annealed state. Machinists and toolmakers use it to fabricate cutting tools, gauges, jigs, and fixtures where hardness and edge retention are required after hardening. The piece weighs 4.04 pounds.

This flat stock is suited for job shops, tool and die shops, and maintenance machining operations that require a reliable O1 tool steel bar in a square cross-section profile. The 36-inch length allows a single piece to be cut down into multiple blanks for small tool components. The annealed condition makes it readily machinable before the hardening and tempering cycle. Toolmakers, machinists, and die makers working on prototype or production tooling will find this stock appropriate for applications demanding oil-quench heat treatment to achieve final hardness.

Key Features

• 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

Compatibility

Designed as an OEM-style stock bar for toolmaking, die making, and precision machining applications requiring O1 oil-hardening tool steel in a flat bar profile.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists using appropriate coolant and tooling rated for tool steel. The bar is supplied in the annealed condition and requires a proper oil-quench hardening and tempering cycle to achieve final hardness — follow the heat treatment parameters specified for AISI O1 tool steel. Use personal protective equipment when cutting or grinding. Secure the workpiece firmly before any machining operation.
