Drill Rod Tool Steels 809941 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809941 is an O1 oil-hardening tool steel flat stock bar sized at 5/64 inches thick, 1-1/2 inches wide, and 36 inches long. Manufactured to AISI Type O1 material specification, this flat stock is designed for tool and die makers, machinists, and metalworking professionals who require a reliable, hardenable steel in a ready-to-use flat bar form. O1 tool steel offers good wear resistance and dimensional stability through the oil-hardening process, making it well suited for fabricating cutting tools, punches, dies, gauges, and other precision tooling components.

This flat stock is intended for use in machine shops, toolrooms, and fabrication environments where precision ground or sawn flat bar material is required prior to hardening and finishing. The 36-inch length provides sufficient stock for multiple tool blanks per piece, minimizing waste. The close thickness and width tolerances support accurate layout and machining before the hardening cycle. It is appropriate for both small-shop and production toolmaking applications.

Key Features

• AISI Type O1 oil-hardening tool steel for reliable heat treatment response
• Thickness of 5/64 inches with a tight tolerance of plus or minus 0.001 inches
• Width of 1-1/2 inches with a tolerance of plus 0.005 inches, minus 0.000 inches
• Length of 36 inches with a tolerance of plus 0.5 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Weight of 1.21 pounds per piece for easy handling and quantity planning

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat bar suitable for toolmaking, die making, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Machining, grinding, and hardening of O1 tool steel flat stock should be performed by qualified machinists or tool and die makers familiar with tool steel heat treatment procedures. Follow the material manufacturer's recommended oil-quench hardening and tempering parameters for AISI O1 tool steel. Use appropriate personal protective equipment when cutting, grinding, or heat treating. Ensure all machining is complete or near-complete before the hardening cycle, as post-hardening material removal is significantly more difficult.
