Drill Rod Tool Steels 809668 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809668 is an O1 oil-hardening tool steel flat stock bar conforming to AISI Type O1 material specification. It measures 1/16 inch thick, 1-1/4 inches wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inches, a width tolerance of plus 0.005 inches to 0.000 inches, and a length tolerance of plus 0.5 inches. Weighing 0.81 pounds, this flat stock is suited for precision toolmaking, die work, punches, and fixtures where tight dimensional tolerances and oil-hardening heat treatment capability are required. Machinists, tool-and-die makers, and fabrication shops work with this material routinely.

O1 tool steel flat stock in this size range is commonly used in job shops, toolrooms, and manufacturing facilities producing cutting tools, forming dies, jigs, and gauges. The 36-inch length allows multiple blanks to be cut from a single bar, making it efficient for small-batch tooling production. This stock is supplied in the annealed condition, ready for machining to final geometry prior to oil-quench hardening and tempering. Metalworking professionals select O1 for its predictable hardening behavior and good dimensional stability during heat treatment.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool-and-die makers using appropriate metalworking equipment. Secure workpieces properly before any cutting or grinding operation. Heat treatment, including oil quenching and tempering, should follow established metallurgical procedures for AISI O1 tool steel and be conducted by personnel familiar with heat treatment safety practices. Personal protective equipment including eye protection and heat-resistant gloves is required during all fabrication and heat treatment operations.
