Value Collection O1D39646 O-1 Drill Rod 39/64 in Tool Steel

Product Description

The VALUE COLLECTION O1D39646 is an O-1 oil hardening drill rod manufactured from tool steel, designed for toolmaking, jig and fixture fabrication, punches, dies, and precision machining applications. Measuring 0.609 inches in diameter (39/64 inch fractional) and 36 inches in overall length, this rod stock is supplied in the annealed condition for machinability, then hardened in oil quench to achieve the wear resistance and toughness O-1 tool steel is known for. Machinists, tool and die makers, and precision fabricators use this material when dimensional stability and fine surface finish are required after heat treatment.

This drill rod is suited for both job shop and production environments where close-tolerance tooling components are produced. The 36-inch length provides practical stock for cutting multiple blanks or machining a single long punch or guide pin. O-1 tool steel offers good machinability in the annealed state and responds predictably to oil hardening, making it a standard choice for low-to-medium production tooling in machine shops and maintenance departments.

Key Features

• O-1 oil hardening tool steel for predictable heat treat response and good wear resistance
• 0.609 inch (39/64 inch) diameter held to close stock tolerances
• 36-inch overall length provides flexible blank cutting options
• Annealed condition supports machining before hardening
• Suitable for punches, dies, guide pins, and custom tooling fabrication

Compatibility

Designed as a general-purpose O-1 tool steel drill rod for use in toolmaking, die making, and precision machining applications where oil-hardening stock at 39/64 inch diameter is specified.

Installation Notes

Cutting and grinding of tool steel rod stock should be performed by a qualified machinist using appropriate speeds, feeds, and coolant to prevent work hardening or surface damage. Hardening and tempering of O-1 tool steel requires controlled heat treatment equipment and should follow recognized metallurgical procedures for this alloy. Always wear appropriate PPE when cutting, grinding, or heat treating metal stock. Secure workpieces properly in a vise or fixture before machining.
