Drill Rod Tool Steels 57716 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57716 is an O1 oil-hardening tool steel flat stock bar sized at 1/16 inch thick, 8 inches wide, and 18 inches long. Conforming to AISI Type O1 specification, this flat stock is a general-purpose tool steel widely used in toolmaking, die work, and precision machining applications. It ships in an annealed, machinable condition ready for oil-quench hardening. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance is plus 0.005 inches to 0.000 inches, and length tolerance is plus 0.25 inches. Edge squareness is 0.003 inches per inch of thickness, and end squareness is 0.004 inches per inch of thickness.

This flat stock is suited for job shops, tool-and-die operations, and maintenance departments requiring precision-ground or pre-finished stock in small quantities. Typical applications include blanking dies, punches, gauges, jigs, fixtures, and cutting tools where oil-hardening steel provides good dimensional stability during heat treatment. The single-piece minimum order quantity makes it practical for prototype work and short-run toolmaking without committing to full bar lengths.

Key Features

• AISI Type O1 oil-hardening tool steel for good toughness and wear resistance after heat treatment
• Tight thickness tolerance of plus or minus 0.001 inches for precise fitment in tooling applications
• Width tolerance of plus 0.005 inches to 0.000 inches supports accurate layout and machining
• Edge squareness of 0.003 inches per inch and end squareness of 0.004 inches per inch of thickness
• Single-piece minimum order quantity suitable for prototype and low-volume toolroom use

Compatibility

Designed as an OEM-style replacement or direct-use flat stock for toolroom, die-making, and precision machining applications requiring AISI Type O1 oil-hardening tool steel in flat bar form.

Installation Notes

Cutting, grinding, and heat treatment of tool steel flat stock should be performed by qualified machinists or tool-and-die makers using appropriate personal protective equipment. O1 steel requires oil quenching during hardening; follow established heat-treating procedures and consult material data sheets for proper austenitizing temperatures. Grinding operations on hardened tool steel should use adequate coolant to prevent surface burns. Always deburr edges after cutting to avoid handling injuries.
