Drill Rod Tool Steels 811794 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 811794 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a ready-to-machine blank with tight dimensional tolerances. Conforming to AISI Type O1 specification, this flat stock measures 7/32 inches thick, 1-1/4 inches wide, and 18 inches long, weighing approximately 1.41 pounds. O1 tool steel offers good wear resistance and machinability in the annealed state, and responds predictably to oil-quench hardening for applications that demand a hardened cutting edge, punch, or forming die.

This flat stock is suited for small toolroom jobs in both job shops and maintenance departments. Typical applications include the fabrication of hand tools, punches, dies, gauges, and general cutting tools. The 18-inch length provides a practical blank for single or multiple short-part setups. The annealed condition allows conventional milling, drilling, and grinding before heat treatment. Machinists and tool and die makers are the primary installers and processors of this material.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable hardening response
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal planning
• Width tolerance of plus 0.005 inches to minus 0.000 inches
• Length tolerance of plus 0.250 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Annealed condition allows full machining prior to heat treat

Compatibility

Designed as a standard O1 oil-hardening flat stock blank suitable for toolroom fabrication of punches, dies, gauges, and cutting tools requiring oil-quench heat treatment.

Installation Notes

Processing of tool steel flat stock is performed by qualified machinists or tool and die makers using conventional metalworking equipment. Secure the workpiece firmly before machining and use appropriate cutting fluids for tool steel. Heat treatment, including hardening and tempering, should follow established metallurgical procedures for AISI O1 and be performed in a controlled-atmosphere or salt-bath furnace where distortion and decarburization are concerns. Always allow the part to reach ambient temperature before final grinding to size.
