Value Collection NS06264204 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264204 is an O1 oil-hardening tool steel flat stock bar measuring 0.375 inches thick, 1.5 inches wide, and 36 inches long. Manufactured to AISI Type O1 specification, this flat stock is held to tight dimensional tolerances — plus or minus 0.001 inches on thickness — making it suitable for toolroom, die-making, and precision machining applications where consistency across the bar matters. At 5.81 pounds per piece, the stock is sized for practical bench use. Machinists, tool-and-die makers, and industrial maintenance technicians commonly work with this material when fabricating punches, dies, gauges, and cutting tools that require oil-quench hardening after machining.

O1 tool steel flat stock is a standard material in job shops, toolrooms, and maintenance departments handling ferrous tooling fabrication. This bar is well suited for low-to-medium production tooling where good machinability in the annealed state and a straightforward oil-quench hardening process are priorities. It is sold as individual flat bar stock for custom cut-to-fit tooling work on conventional mills, lathes, grinders, and surface grinders.

Key Features

• AISI Type O1 oil-hardening tool steel — oil-quench hardenable for wear-resistant tooling applications
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal and fit-up
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches for oversize material allowance
• Squareness held to 0.003 inches per inch on edges and 0.004 inches per inch on ends
• Ships as a single full-length bar — no minimum quantity beyond one piece

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat bar for use in standard toolroom and machining operations requiring AISI Type O1 material specification.

Installation Notes

O1 tool steel flat stock is typically cut, milled, and ground to final dimensions in the annealed condition before hardening. Hardening and tempering operations should be performed by a qualified machinist or heat-treat technician following recognized metallurgical procedures for AISI O1 tool steel. Use appropriate personal protective equipment when cutting or grinding tool steel. Follow all applicable shop safety standards and equipment manufacturer guidelines when operating machine tools.
