Value Collection NS06140206 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06140206 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die-making, jig fabrication, and precision machining applications. The blank measures 5/8 inch thick, 2 inches wide, and 18 inches long, with a thickness tolerance of +/- 0.001 inches, a width tolerance of +0.005 / -0.000 inches, and a length tolerance of +0.25 inches. O1 tool steel is a cold-work grade known for its consistent hardenability, fine grain structure, and good dimensional stability after heat treatment. Machinists and toolroom technicians rely on this material for producing punches, dies, gauges, and cutting tools that require a hard, wear-resistant working surface after oil-quench hardening.

This flat stock is suited for toolroom and industrial machining environments where ground or precision-tolerance stock is specified. It is appropriate for both small-shop and production toolroom use, covering applications such as form dies, blanking punches, broaches, taps, and reamers. The pre-cut 18-inch length reduces saw time and material waste for common short-run tooling jobs. Machinists, tool-and-die makers, and metalworking professionals select O1 flat stock when predictable oil-quench response and close dimensional tolerances are required from the as-supplied bar.

Key Features

• AISI Type O1 oil-hardening tool steel for consistent heat-treat response
• Thickness tolerance of +/- 0.001 inches for tight-tolerance tooling work
• Width tolerance of +0.005 / -0.000 inches
• Length tolerance of +0.25 inches on the 18-inch blank
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Ready-to-machine flat stock format minimizes setup and material prep time

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock blank for general toolroom fabrication; verify dimensional requirements against your specific tooling design before ordering.

Installation Notes

Tool steel flat stock is machined and heat-treated by qualified machinists or tool-and-die makers using appropriate metalworking equipment. Follow established shop safety procedures when cutting, grinding, or milling tool steel, including the use of appropriate personal protective equipment. Oil-quench hardening of O1 steel should be performed in accordance with the material supplier's published heat-treatment guidelines and applicable shop procedures. Allow the workpiece to reach ambient temperature before taking finish measurements to confirm dimensional conformance.
