Value Collection NS06124150 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06124150 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, punches, and precision machining applications. Manufactured from AISI Type O1 tool steel, this flat stock measures 0.375 inches thick, 1.5 inches wide, and 18 inches long, and weighs 2.9 pounds. O1 tool steel is known for its predictable oil-quench hardening behavior and good dimensional stability after heat treatment. Machinists, tool and die makers, and metalworking shops rely on this material for fabricating blades, gauges, and custom tooling components where close tolerances and consistent stock dimensions are required.

This flat stock is suited for job shops, maintenance departments, and toolrooms handling light to medium toolmaking tasks. The 18-inch length provides workable stock for a range of cut-to-size applications. The tight thickness tolerance of plus or minus 0.001 inches makes it appropriate for precision tool blanks and wear parts where dimensional accuracy matters from the start of machining. It is typically processed by milling, grinding, or sawing before hardening and tempering to final working hardness.

Compatibility

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

Installation Notes

O1 tool steel flat stock is worked by qualified machinists or tool and die makers using standard milling, grinding, and sawing equipment. Always follow established heat treatment procedures for O1 steel, including proper preheat, hardening temperature, oil quench, and temper cycles, using calibrated furnace equipment. Wear appropriate PPE during all machining and heat treatment operations. Consult applicable shop safety standards and material data sheets before processing.
