Drill Rod Tool Steels 57712 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57712 is an O1 oil-hardening tool steel flat stock bar used in precision toolmaking, die making, and machining applications. Manufactured to AISI Type O1 specifications, this flat stock measures 0.0625 inches thick, 3.5 inches wide, and 18 inches long, with a weight of 1.13 pounds per piece. O1 tool steel is valued for its consistent oil-hardening response, good wear resistance, and machinability in the annealed state. Tight dimensional tolerances - including a thickness tolerance of plus or minus 0.001 inches - make this stock suitable for applications where close-fit accuracy is required before and after heat treatment.

This flat stock is used primarily in tool and die shops, machine shops, and maintenance departments for fabricating punches, dies, gauges, cutting tools, and fixtures. The 18-inch length and 3.5-inch width provide workable stock for a range of small to mid-sized tooling blanks. Machinists and tool-and-die makers typically work this material in the annealed condition before sending it out for oil hardening and tempering to final hardness. It suits both one-off prototype work and short-run production tooling.

Key Features

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, gauging, and fixture fabrication applications where oil-quench hardenable material is specified.

Installation Notes

Machining and grinding of O1 tool steel should be performed in the annealed condition prior to heat treatment. Heat treatment, including oil hardening and tempering, should be performed by a qualified heat treater following established metallurgical procedures for AISI O1 tool steel. Use appropriate personal protective equipment when cutting, grinding, or machining tool steel stock. Follow all applicable shop safety standards when handling sharp-edged flat bar stock.
