Drill Rod Tool Steels 57797 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57797 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a precision-ground blank ready for hardening and finishing. Ground to 0.5625 inches thick, 0.75 inches wide, and 18 inches long, this flat stock ships in annealed condition and reaches high hardness after oil quench. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for close-tolerance tooling applications where dimensional consistency before heat treat is critical. The piece weighs approximately 2.18 pounds.

O1 tool steel flat stock of this size is commonly used in the fabrication of punches, dies, jigs, fixtures, gauges, and cutting tools in job shops and tool rooms. Its oil-hardening characteristic produces minimal distortion during the quench cycle compared to water-hardening grades, making it a practical choice for intricate or thin cross-section tooling. Licensed machinists and toolmakers working in general metalworking, mold making, and precision manufacturing are the primary installers and users of this material.

Installation Notes

Cutting and grinding of tool steel flat stock should be performed with appropriate metalworking equipment and personal protective equipment including eye protection and hearing protection. Heat treating O1 tool steel requires oil quenching at temperatures specified by your heat treatment process plan; consult a qualified metallurgical reference before hardening. Machining to final dimensions before heat treat is recommended to avoid post-hardening grinding where possible. Follow applicable shop safety standards when cutting, grinding, or handling tool steel stock.
