Drill Rod Tool Steels 66806 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 66806 is an O1 oil-hardening tool steel flat bar cut to 36 inches long, 1.5 inches wide, and 0.125 inches thick. O1 is a general-purpose oil-hardening tool steel (AISI Type O1) known for its machinability in the annealed state and its ability to hold a sharp edge after hardening. This flat stock is used in toolmaking, die work, jig fabrication, and precision machining applications. Machinists, toolmakers, and fabricators work with this material to produce punches, dies, blades, gauges, and fixtures where dimensional accuracy and hardenability are critical requirements.

This flat stock is suited for toolroom and production shop use across a wide range of trades and industries. The 36-inch length provides a full bar for layout and cutting to finished part dimensions. The 0.125-inch thickness and 1.5-inch width make it a practical choice for thin die plates, small blades, and precision flat tooling components. It is supplied in the annealed condition, ready for machining prior to heat treatment.

Key Features

• AISI Type O1 oil-hardening tool steel construction for reliable through-hardening in oil quench
• Tight thickness tolerance of plus or minus 0.001 inches for precision toolmaking applications
• Width tolerance of plus 0.005 inches, minus 0.000 inches ensures stock is never undersize
• Length tolerance of plus 0.5 inches provides usable overage for facing or squaring operations
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Supplied in annealed condition for full machinability before hardening

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar suitable for general toolroom, die shop, and precision fabrication applications requiring AISI Type O1 material specification.

Installation Notes

Cutting, grinding, and machining should be performed in the annealed state prior to heat treatment. Oil hardening and tempering should be carried out by a qualified heat treater following established procedures for AISI O1 tool steel. Use appropriate personal protective equipment when grinding or cutting tool steel stock. Follow applicable shop safety codes and material handling procedures when storing or moving bar stock.
