Value Collection NS06148001 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06148001 is an O1 oil-hardening tool steel flat stock bar suited for toolmakers, machinists, and die makers working in job shops or maintenance departments. The bar measures 0.75 inches thick by 0.75 inches wide by 18 inches long and conforms to AISI Type O1 oil-hardening tool steel specification. Thickness and squareness tolerances are held to plus or minus 0.001 inches, making this stock dimensionally consistent for layout work, blanking dies, punches, gauges, and similar precision tooling applications. Weight is 2.91 pounds per piece.

O1 tool steel flat stock in this size range is commonly used in tool and die shops, prototype machining, and maintenance-repair-operations (MRO) settings. It is a general-purpose oil-hardening grade that machines well in the annealed condition and responds predictably to heat treatment when full hardness is required. Typical applications include small punches, die blades, forming tools, scrapers, and wear pads where dimensional accuracy before and after heat treat is critical.

Key Features

• AISI Type O1 oil-hardening tool steel — machines cleanly in annealed state, hardens well in oil quench
• Thickness tolerance of plus or minus 0.001 inches for precise pre-grind stock allowance
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.25 inches, minus 0.000 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Ready-to-use flat stock format — no further profiling required for most tooling blanks

Compatibility

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

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool and die makers familiar with O1 steel handling procedures. Always wear appropriate PPE when cutting or grinding. Material is supplied in the annealed condition; harden and temper according to established heat treatment practices for AISI O1 tool steel before putting tooling into service under load. Allow adequate stock for finish grinding after heat treatment to correct any minor distortion.
