Drill Rod Tool Steels 812017 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 812017 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Conforming to AISI Type O1 material specification, this flat stock measures 0.25 inches thick, 1.25 inches wide, and 18 inches long, weighing 1.61 pounds. O1 tool steel is a versatile cold-work grade known for its good dimensional stability during heat treatment, moderate toughness, and ability to hold a fine edge after hardening. It ships in annealed condition and requires oil quenching to achieve full hardness. Machinists, tool and die makers, and metalworking shops are the primary installers and end users of this material.

This flat stock is suited for fabricating punches, dies, cutting tools, gauges, jigs, and fixtures where hardness and wear resistance are required after heat treatment. The 18-inch length and pre-cut flat bar profile reduce setup time compared to raw stock that requires further milling to dimension. The material is supplied in a soft, machinable annealed state, ready for finish machining before hardening. Typical applications span both job shop and production toolroom environments handling precision cold-work tooling.

Key Features

• AISI Type O1 oil-hardening tool steel construction for reliable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for tight dimensional control
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.25 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Supplied in annealed condition, ready for machining prior to hardening

Compatibility

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

Installation Notes

Machining and heat treatment of O1 tool steel flat stock is performed by qualified tool and die makers or metalworking professionals using appropriate metal-cutting equipment. Always machine to final dimensions before hardening, as the oil-quench process will affect dimensions and surface condition. Follow established metallurgical procedures and equipment manufacturer guidelines for austenitizing temperature, quench medium, and tempering cycles when hardening this material. Use appropriate personal protective equipment when handling cutting fluids, quench oils, and hot workpieces.
