Value Collection NS06264881 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264881 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die-making, and precision machining applications. Measuring 0.5 inches thick, 1 inch wide, and 36 inches long, this flat stock is cut from AISI Type O1 tool steel and is supplied in an annealed condition ready for machining, grinding, and subsequent oil-quench hardening. With a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 to minus 0.000 inches, this bar holds the tight dimensional accuracy required for jigs, fixtures, gauges, punches, and cutting tools. Machinists, tool-and-die makers, and fabrication shops are the primary users of this material.

O1 tool steel flat stock is well-suited for low- to medium-volume tooling applications where moderate toughness and good machinability in the annealed state are required. Typical uses include blanks for knife blades, form tools, broaches, taps, and precision gauges. The 36-inch bar length accommodates most bench and mill setups without requiring additional cutting. This flat stock is appropriate for both job shop and production toolroom environments where dimensional consistency from piece to piece is critical.

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock blank for use in toolmaking, die-making, fixture building, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Machining of O1 tool steel should be performed in the annealed state using appropriate cutting fluids and high-speed steel or carbide tooling. Hardening requires heating to proper austenitizing temperature followed by an oil quench per the material specification — consult a qualified metallurgist or heat treat shop for process parameters. Always wear appropriate PPE when cutting, grinding, or heat treating tool steel. Deburr all edges before handling or assembly into tooling fixtures.
