Drill Rod Tool Steels 57726 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57726 is an O1 oil-hardening tool steel flat stock bar measuring 0.125 inches thick, 5 inches wide, and 18 inches long. Manufactured to AISI Type O1 material specification, this flat stock is intended for toolmakers, machinists, and die makers who require a reliable, machinable blank before hardening. O1 tool steel is a general-purpose oil-hardening grade known for its good machinability in the annealed state and its ability to hold precise dimensions through the hardening process. The piece weighs approximately 3.22 pounds and is held to tight dimensional tolerances across thickness, width, and length.

This flat stock is suited for fabrication of punches, dies, gauges, cutting tools, jigs, and fixtures in tool and die shops, machine shops, and maintenance departments. It works in both light industrial and heavy production environments where a pre-cut, near-net-shape blank reduces setup time. The 18-inch length and 5-inch width provide a workable blank for a wide range of tooling applications. Professionals working with this material typically machine it in the annealed condition and then oil-quench to achieve the desired hardness.

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock blank for use in tool and die making, fixture fabrication, and precision machining applications wherever AISI Type O1 material specification is required.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists following established shop practices. Always machine O1 tool steel in the annealed condition before hardening. Oil-quench heat treatment must be performed in accordance with the material manufacturer guidelines and applicable shop safety protocols. Secure the workpiece properly before cutting or grinding to prevent movement and maintain dimensional accuracy.
