Value Collection NS06148159 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06148159 is an O1 oil-hardening tool steel flat stock bar sized at 0.75 inches thick, 1.5 inches wide, and 18 inches long. O1 tool steel is an oil-hardening cold-work steel known for its good wear resistance, dimensional stability during heat treatment, and ease of machining in the annealed state. This flat stock ships in the annealed condition, ready for machining to final shape before hardening. It is used by toolmakers, machinists, and die makers fabricating punches, dies, gauges, cutting tools, and precision fixtures. The part weighs 5.81 pounds.

This flat stock is suited for job shops, tool and die operations, and maintenance machining applications where close-tolerance O1 tool steel bar is required. Typical uses include blanking dies, form punches, woodworking tools, taps, and gauging fixtures that require a hard, wear-resistant surface after oil-quench heat treatment. The 18-inch length provides workable stock for most bench-scale tooling projects without requiring further cut-down from a longer bar.

Key Features

• AISI Type O1 oil-hardening tool steel — stable geometry during oil-quench hardening
• Tight thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.005 inches, minus 0.000 inches maintains consistent material allowance
• Length tolerance of plus 0.25 inches provides sufficient stock for facing to final dimension
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Annealed condition supports straightforward machining before heat treatment

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock suitable for general tool and die, gauging, and precision fixture fabrication applications requiring AISI Type O1 material specification.

Installation Notes

O1 tool steel flat stock is machined by qualified toolmakers and machinists using standard metalworking equipment. Always machine to final dimensions before hardening, as post-hardening stock removal is limited to grinding. Oil-quench heat treatment should follow the material supplier recommendations for AISI O1 and be performed in a controlled environment by personnel experienced with tool steel heat treatment. Handle edges with care — ground or milled edges can be sharp.
