Value Collection NS06148100 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06148100 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, jig fabrication, and precision machining applications. Measuring 0.75 inches thick, 1 inch wide, and 18 inches long, this flat stock is supplied to tight tolerances suitable for tool and die work. The AISI Type O1 designation means the steel is designed to be hardened in oil quench, producing a hard, wear-resistant surface with minimal distortion. Machinists, tool and die makers, and metal fabricators work with this material before and after heat treatment to produce punches, dies, gauges, and cutting tools.

This flat stock is suited for use in job shops, tool rooms, and manufacturing facilities where precision ground or pre-finished bar stock is required as raw material. The 18-inch length is a practical cut for producing multiple smaller tool components from a single piece. The combination of close thickness, width, and length tolerances makes this bar ready to use as received for many layout and machining operations without additional surface preparation.

Key Features

• AISI Type O1 oil-hardening tool steel construction for consistent hardenability
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.25 inches
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Weighs 3.87 pounds per piece — suitable for bench and vise work without lifting equipment

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications where O1 grade material is specified.

Installation Notes

This is raw material stock handled by machinists and tool and die makers. Cutting, grinding, and drilling should be performed with tooling rated for tool steel. Heat treatment to full hardness requires oil quench per AISI O1 procedures and should be performed by a qualified heat treater familiar with tool steel. Allow the stock to reach ambient temperature before precision measurement. Use appropriate personal protective equipment when machining or handling freshly cut edges.
