Drill Rod Tool Steels 57718 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57718 is an O1 oil-hardening tool steel flat stock bar used in precision toolmaking, die work, jig fabrication, and general machine shop applications. Conforming to AISI Type O1 specifications, this flat stock measures 3/32 inches thick, 1-1/4 inches wide, and 18 inches long, with a package weight of 0.61 pounds. O1 tool steel is known for its consistent oil-hardening response and good machinability in the annealed state, making it a standard material choice for tool and die makers, machinists, and fabricators who require dimensional accuracy and reliable heat-treat performance.

This flat stock is suited for fabricating cutting tools, gauges, punches, dies, and other precision components that require subsequent hardening and tempering. The 18-inch length allows for moderate run production of small components or single-piece tooling. It is typically used in job shops, tool rooms, and manufacturing environments where O1 tool steel is the specified material. Individual pieces are sold in single-unit quantities with no minimum order beyond one piece.

Installation Notes

Machining and grinding of O1 tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate cutting tools and coolant. Heat treating, including hardening and tempering, must follow AISI O1 metallurgical guidelines and should be performed by personnel with applicable thermal processing experience. Always use proper personal protective equipment when cutting, grinding, or heat treating tool steel.
