Value Collection NS06132153 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06132153 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Manufactured to AISI Type O1 specifications, this flat stock measures 0.5 inches thick, 1.5 inches wide, and 18 inches long, weighing 3.87 pounds. O1 tool steel is known for its excellent edge retention and machinability in the annealed state, making it a standard choice for cutting tools, punches, dies, and gauges. Thickness tolerance is held to plus or minus 0.001 inches, supporting close-tolerance work.

This flat stock is suited for job shops, tool-and-die operations, and maintenance shops requiring precise raw material stock. It is commonly used to fabricate custom tooling, jigs, fixtures, and blades. The 18-inch length provides enough material for multiple cuts on short tooling components. Width tolerance is plus 0.005 inches and minus 0.000 inches, and length tolerance is plus 0.25 inches. Edge squareness is held to 0.003 per inch of thickness, and end squareness to 0.004 per inch of thickness, meeting standard tool steel flat bar tolerances.

Compatibility

Designed as a standard AISI O1 oil-hardening tool steel flat bar suitable for use in tool-and-die, fixture fabrication, and general machining applications requiring oil-quench heat treatment.

Installation Notes

Machining and grinding of O1 tool steel should be performed by qualified machinists or tool-and-die makers using appropriate cutting fluids and wheel dressings. When heat treating, follow AISI O1 austenitizing and oil-quench procedures using calibrated furnace equipment. Always wear appropriate PPE when cutting, grinding, or heat treating. Confirm final dimensions after machining and before hardening, as distortion can occur during the quench cycle.
