Drill Rod Tool Steels 57715 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57715 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a precision-ground blank ready for heat treatment. Conforming to AISI Type O1 material specification, it measures 1/16 inch thick, 6 inches wide, and 18 inches long, with a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.005 inches to 0.000 inches. At 1.93 pounds, this flat stock ships as a single piece and is sized for one-off tool and die work, jig plates, and fixture components where close dimensional control is essential before hardening.

O1 oil-hardening tool steel is widely used in low-to-medium production tooling where good wear resistance, moderate toughness, and predictable oil-quench response are required. This flat stock format suits applications such as blanking dies, forming tools, gauges, and small fixture plates in job shop and maintenance machining environments. The 18-inch length provides enough material for most single-component tool blanks without excess waste. Machinists working in both manual and CNC environments will find this size practical for typical bench-scale tooling projects.

Key Features

• AISI Type O1 oil-hardening tool steel meets standard material specification for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches supports close-tolerance layout and grinding work
• Width tolerance of plus 0.005 inches to 0.000 inches ensures the blank is never undersize on width
• Length tolerance of plus 0.25 inches provides extra material for facing or squaring the ends
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-piece packaging with no minimum order beyond one unit reduces inventory commitment

Compatibility

Designed as a standard-format O1 oil-hardening tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications where AISI Type O1 material is specified.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by a qualified machinist or toolmaker familiar with O1 oil-hardening procedures. Use appropriate personal protective equipment when sawing or grinding. Oil quenching and tempering operations must follow established metallurgical practice for O1 steel and should be conducted in a properly equipped heat-treat area. Deburr all edges before handling to prevent injury.
