Drill Rod Tool Steels 809260 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809260 is an O1 oil-hardening tool steel flat stock bar sized at 3/64 inches thick, 1/2 inch wide, and 18 inches long. Conforming to AISI Type O1 specification, this flat stock is a versatile toolroom material used for making punches, dies, gauges, cutting tools, and general toolmaking components. The tight thickness tolerance of plus or minus 0.001 inches makes it suitable for precision applications where dimensional accuracy matters before and after heat treatment. Machinists, tool and die makers, and industrial maintenance technicians work with this material in both job shop and manufacturing environments.

O1 tool steel flat stock in this size range is commonly used in light to medium tooling applications. The 18-inch length allows single-piece blanks to be cut for small dies, blades, or shaped cutting tools. The 1/2-inch width and 3/64-inch thickness suit thin profile tooling inserts, scraper blades, and small flat punches. This piece ships as a single unit and is intended for bench or machine shop use where stock is cut to final length and then hardened through an oil-quench process.

Key Features

• AISI Type O1 oil-hardening tool steel for consistent hardenability in oil quench
• Thickness tolerance of plus or minus 0.001 inches for precision pre-grind fitment
• Width tolerance of plus 0.005 inches / minus 0.000 inches
• Length tolerance of plus 0.250 inches to allow for facing and squaring
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Ready-to-machine flat stock format eliminates rough profiling steps

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for toolroom, die-making, and general precision machining applications requiring oil-quench heat treatment.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by a qualified machinist using appropriate metalworking equipment. All heat treatment operations, including oil quenching and tempering, should follow established metallurgical procedures for AISI O1 tool steel. Wear appropriate personal protective equipment when cutting, grinding, or heat treating. Verify final dimensions after any grinding or squaring operations prior to hardening.
