Value Collection NS06264840 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264840 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, punches, gauges, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 0.5 inches thick, 0.625 inches wide, and 36 inches long, with a weight of 3.23 pounds per piece. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications that require tight dimensional control before heat treatment. Machinists, tool and die makers, and industrial fabricators work with this material to produce custom tooling components that will be oil-quenched and hardened after machining.

O1 tool steel flat stock is commonly used in job shops, tool rooms, and maintenance departments where custom tooling is fabricated in-house. This bar stock is appropriate for producing punches, dies, jigs, fixtures, and wear parts that require moderate toughness and good dimensional stability through the hardening process. The 36-inch length allows for multiple pieces to be cut from a single bar depending on the finished part dimensions required. It is suited for both light production and prototype tooling work.

Key Features

• AISI Type O1 oil-hardening tool steel for good machinability in the annealed state
• Thickness held to plus or minus 0.001 inches for precision pre-grind stock allowance
• Width tolerance of plus 0.005 inches, minus 0.000 inches for consistent fit in tooling layouts
• Length tolerance of plus 0.5 inches ensures full usable length on every bar
• Edge squareness: 0.003 inches per inch of thickness; end squareness: 0.004 inches per inch of thickness
• Single-piece packaging with a minimum order quantity of one bar

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat bar suitable for use in standard toolmaking, die making, and precision machining applications where AISI Type O1 material specification is required.

Installation Notes

O1 tool steel flat stock is machined in the annealed condition using conventional milling, turning, or surface grinding equipment. Hardening requires oil quenching per standard heat treatment procedures for AISI O1 tool steel and should be performed by a qualified heat treater or machinist familiar with tool steel processing. Always wear appropriate PPE when cutting, grinding, or handling bar stock. Follow applicable shop safety standards and equipment manufacturer guidelines when machining or heat treating tool steel.
