Value Collection NS06264931 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264931 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 0.5 inches thick, 1.75 inches wide, and 36 inches long, with a weight of 9.03 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy is critical before and after heat treatment. Machinists, tool and die makers, and industrial maintenance technicians work with this material to fabricate punches, dies, gauges, and similar hardened tooling components.

O1 tool steel is a general-purpose oil-hardening grade well suited for low-to-medium production tooling. This flat stock is commonly used in job shop environments, tool rooms, and manufacturing maintenance departments. It machines in the annealed condition and achieves high hardness after oil quench heat treatment. The 36-inch length provides a standard stock length for layout and cut-to-size work on band saws, manual mills, and surface grinders. Width and length tolerances allow for straightforward cleanup cuts before final machining to finished dimensions.

Key Features

• AISI Type O1 oil-hardening tool steel — machines well in annealed state and hardens after oil quench
• Thickness held to plus or minus 0.001 inches for consistent pre-grind stock allowance
• Width tolerance of plus 0.005 inches, minus 0.000 inches — material is never undersize on width
• Length tolerance of plus 0.5 inches — full usable length guaranteed
• Edge squareness: 0.003 inches per inch of thickness; end squareness: 0.004 inches per inch of thickness
• Standard 36-inch bar length compatible with common tool room stock storage and saw capacity

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar for use in general tool room, die shop, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Cutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment including band saws, milling machines, and surface grinders. Material is supplied in the annealed condition and requires heat treatment by a qualified tool and die maker or heat treat facility to achieve working hardness. Wear appropriate PPE including eye protection and gloves when cutting or grinding. Follow shop safety procedures and applicable OSHA guidelines for metalworking operations.
