Value Collection NS06264105 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06264105 is an O1 oil-hardening tool steel flat stock bar used in precision toolmaking, die work, punches, gauges, and general machining applications. It measures 3/8 inches thick by 3/8 inches wide by 36 inches long and holds a tight thickness tolerance of plus or minus 0.001 inches. O1 tool steel offers good machinability in the annealed state and hardens well in oil quench, making it a standard choice for toolroom stock. Machinists, tool-and-die makers, and maintenance shops keep this size on hand as raw material for custom tooling and fixture components.

This flat stock is suited for toolroom and job-shop environments where accurate, square-edged raw material is needed before grinding, hardening, and tempering operations. The 36-inch length provides a useful starting blank for multiple smaller tools or gauges. Edge squareness is held to 0.003 inches and end squareness to 0.004 inches per inch of thickness, ensuring reliable fitment in precision setups without requiring extensive pre-machining to true up the stock.

• AISI Type O1 oil-hardening tool steel for predictable heat-treat response
• Tight thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.005 inches / minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Edge squareness held to 0.003 inches; end squareness 0.004 inches per inch of thickness
• 36-inch length provides ample stock for multiple tooling blanks

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat bar suitable for toolroom, die shop, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Cutting, grinding, and heat-treating tool steel should be performed by qualified machinists or tool-and-die tradespeople using appropriate personal protective equipment. Follow established shop safety practices when sawing or abrasive cutting this stock. Oil-quench hardening and tempering should follow AISI O1 heat-treat guidelines; improper quench rates or temperatures can result in warping or cracking. Allow stock to reach a stable temperature before precision layout or grinding operations.
