Drill Rod Tool Steels 810656 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 810656 is an O1 oil-hardening tool steel flat stock measuring 0.125 inches thick, 12 inches wide, and 18 inches long, with a weight of 7.33 pounds. Manufactured to AISI Type O1 specification, this flat stock is produced from tool steel and held to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.005 inches on width, and plus 0.25 inches on length. It is suited for toolmakers, machinists, and die makers who require a reliable, consistent-dimension stock for fabricating dies, punches, gauges, jigs, and cutting tools that will be finish-hardened in oil.

O1 tool steel flat stock is a standard material in job shops, tool-and-die operations, and maintenance machining environments. It is commonly used in both small-production and prototype tooling applications where the workpiece will be machined in the annealed state and then oil-quenched to achieve working hardness. The 12-inch width and 18-inch length make this piece suitable for medium-format die plates, fixture blanks, and wear-component blanks. A licensed machinist or toolmaker typically performs the rough and finish machining before heat treatment.

• 7.33 pounds per piece, ready for immediate layout and machining

Compatibility

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

Installation Notes

Machining of O1 tool steel flat stock should be performed in the annealed condition prior to heat treatment. Secure the workpiece properly in a mill vise or surface grinder to maintain dimensional accuracy during material removal. Heat treatment, including oil quenching and tempering, should be performed by a qualified heat treater following established metallurgical procedures. Always wear appropriate PPE when cutting, grinding, or heat treating tool steel.
