Drill Rod Tool Steels 57977 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57977 is an O1 oil-hardening tool steel flat stock bar sized at 0.625 inches thick, 5 inches wide, and 36 inches long. Manufactured to AISI Type O1 material specification, this flat stock is used in tool and die work, jig and fixture fabrication, and precision machining applications where close dimensional tolerances are required. The stock ships with a thickness tolerance of plus or minus 0.001 inches, a width tolerance of plus 0.005 inches to minus 0.000 inches, and a length tolerance of plus 0.5 inches. Machinists, tool and die makers, and metalworking fabricators work with this material to produce punches, dies, gauges, and custom tooling components that will be oil-quench hardened after machining.

This flat stock is suited for machine shops, tool rooms, and fabrication facilities handling low-distortion oil-hardening tool steel. O1 tool steel offers good machinability in the annealed condition and responds predictably to oil quenching, making it a standard choice for short-run tooling, blanking dies, and wear-resistant components. The 36-inch length accommodates a wide range of stock removal and custom cutting requirements. This piece weighs approximately 32.22 pounds as packaged.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Always follow proper personal protective equipment guidelines when cutting or grinding steel. Heat treatment, including oil quenching and tempering, should be performed according to established metallurgical procedures for AISI O1 tool steel. Consult applicable shop safety and fire codes when working with quenching oils.
