Drill Rod Tool Steels 57713 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57713 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Conforming to AISI Type O1 specification, this flat stock measures 1/16 inch thick, 4 inches wide, and 18 inches long with tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.005 inches on width, and plus 0.25 inches on length. The piece weighs 1.29 pounds. O1 tool steel is valued for its excellent machinability in the annealed state and its ability to hold sharp edges after oil quenching and tempering, making it a go-to material for blanks, punches, and gauges.

This flat stock is suited for job shops, tool and die makers, and prototype fabricators who require precise, ready-to-machine stock in small quantities. Typical uses include cutting tool blanks, forming dies, jigs, fixtures, and wear plates. The flat bar format reduces setup time by providing stock that is close to final dimensions, minimizing material removal before heat treatment. It is appropriate for both one-off tooling jobs and small production runs where dimensional consistency is critical.

Key Features

• AISI Type O1 oil-hardening tool steel for reliable hardening response with standard oil quench
• Thickness tolerance of plus or minus 0.001 inches for close-tolerance tooling work
• Width tolerance of plus 0.005 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
• Ready-to-machine annealed condition allows drilling, milling, and grinding before hardening
• Single-piece minimum order quantity suits low-volume tooling and prototype needs

Compatibility

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

Installation Notes

Machining and heat treatment of tool steel flat stock should be performed by qualified machinists or tool and die makers familiar with O1 oil-hardening procedures. Always follow established shop safety practices when cutting, grinding, or heat treating tool steel. Oil quenching should be performed in a controlled environment using appropriate quench oil and personal protective equipment. Consult applicable material safety data and heat treatment guidelines for AISI O1 before hardening.
