Drill Rod Tool Steels 57747 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57747 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, jig fabrication, and precision machining applications. Conforming to AISI Type O1 material specification, this flat stock measures 0.25 inches thick, 8 inches wide, and 18 inches long, with a finished weight of 9.02 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy is critical before and after heat treatment. Machinists, tool and die makers, and fabricators who require a reliable oil-hardening stock will find this bar ready for layout, machining, and hardening operations.

O1 tool steel flat stock is a standard material in job shops, toolrooms, and industrial fabrication environments. It is used to produce punches, dies, gauges, cutting tools, fixtures, and jigs that require good wear resistance and moderate toughness after oil quenching. This bar is supplied in the annealed condition and is intended for machining to final dimensions prior to heat treatment. The 8-inch width and 18-inch length make it suitable for medium to large tool and die components where a wider flat profile is needed.

Key Features

• AISI Type O1 oil-hardening tool steel, supplied in annealed condition for ease of machining
• Thickness tolerance of plus or minus 0.001 inches for precision fit in close-tolerance tooling applications
• Width tolerance of plus 0.005 inches, minus 0.000 inches for consistent material sizing
• Length tolerance of plus 0.25 inches for standard stock allowance
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Weighs 9.02 pounds per piece, suitable for medium to large die and fixture components

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock for use in toolroom, die making, and precision fabrication applications requiring oil-quench heat treatment.

Installation Notes

Machining and heat treatment of tool steel flat stock should be performed by qualified tool and die makers or machinists familiar with O1 steel processing. Always machine to final dimensions in the annealed state before performing oil-hardening heat treatment. Follow established shop safety procedures when handling large flat stock, including proper lifting technique and use of appropriate PPE. Consult applicable material and heat treatment standards before specifying hardness targets or quench procedures.
