Drill Rod Tool Steels 57723 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57723 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, jig and fixture fabrication, dies, punches, and precision machined components. Conforming to AISI Type O1 specifications, this flat stock measures 3/32 inches thick, 8 inches wide, and 18 inches long, with a weight of 3.87 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where tight dimensional control is required before hardening. It is supplied in the annealed condition and is intended for oil-quench hardening by a qualified machinist or tool and die maker.

This flat stock is used in tool and die shops, machine shops, and maintenance and repair operations requiring a reliable, machinable steel that responds predictably to oil-hardening heat treatment. Typical applications include blanking dies, forming tools, gauges, and precision fixtures. The wide 8-inch profile supports layout and machining of larger tool components from a single piece, reducing material joints in critical tooling.

Key Features

• AISI Type O1 oil-hardening tool steel - predictable hardening response and good wear resistance after heat treatment
• Thickness tolerance of plus or minus 0.001 inches for tight dimensional control
• Width tolerance of plus 0.005 inches, minus 0.000 inches for consistent stock removal planning
• Length tolerance of plus 0.25 inches for allowance in cutoff operations
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Supplied in flat stock form - ready for sawing, milling, grinding, or EDM operations prior to hardening

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications requiring annealed stock in 3/32 x 8 x 18 inch dimensions.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metal-cutting equipment. All heat treating operations, including oil quenching, must follow established metallurgical procedures and applicable shop safety protocols. Ensure proper personal protective equipment is used when cutting, grinding, or heat treating. Do not attempt to harden without proper furnace equipment and quench media rated for O1 tool steel.
