Drill Rod Tool Steels 863572 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 863572 is an O1 oil-hardening tool steel flat bar cut to 3/32 inches thick, 1-3/4 inches wide, and 18 inches long. O1 is a general-purpose oil-hardening tool steel known for its good machinability in the annealed state and its ability to hold a sharp edge after heat treatment. This flat stock ships in the annealed (soft) condition, allowing machinists, toolmakers, and die makers to machine it to final shape before hardening. It is suited for fabricating cutting tools, punches, dies, jigs, fixtures, gauges, and similar precision components where dimensional accuracy and material consistency are required.

This flat stock is used in machine shops, tool-and-die operations, and maintenance departments across manufacturing, metalworking, and fabrication industries. It is appropriate for both one-off tooling and short-run production of tool components. The 18-inch length is a standard intermediate size that supports multiple smaller blanks from a single piece. Licensed machinists and toolmakers are the primary installers and users of this material.

Key Features

• AISI Type O1 oil-hardening tool steel - machines well in the annealed state and responds predictably to oil-quench hardening
• Tight thickness tolerance of plus or minus 0.001 inches supports precision layout and grinding work
• Width tolerance of plus 0.005 inches, minus 0.000 inches ensures the stock is never undersize on the critical width dimension
• Length tolerance of plus 0.25 inches allows for clean squaring and facing on both ends
• Edge squareness held to 0.003 inches per inch of thickness; end squareness to 0.004 inches per inch of thickness
• Single-piece minimum order quantity suits prototype and repair work without requiring bulk purchase

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications where O1 material specification is required.

Installation Notes

Machining of O1 tool steel flat stock is performed by qualified machinists using standard milling, grinding, and sawing equipment appropriate for tool steel. Heat treatment - including annealing, hardening, and tempering - should follow established metallurgical procedures for AISI O1 and be performed by personnel familiar with tool steel heat treatment practices. Always allow the material to reach ambient temperature before performing precision layout or finish grinding. Consult applicable shop safety standards when cutting or grinding tool steel stock.
