Value Collection O1D45646 O-1 Drill Rod 45/64 in Tool Steel

Product Description

The VALUE COLLECTION O1D45646 is an O-1 oil hardening drill rod machined from tool steel to a diameter of 0.703 inches (45/64 inch fraction) and cut to a 36-inch overall length. O-1 tool steel is a general-purpose oil-hardening grade known for its dimensional stability during heat treatment and its ability to hold a sharp cutting edge after hardening and tempering. This drill rod is used by machinists, toolmakers, and die makers as raw stock for fabricating punches, dies, reamers, drill blanks, and other precision tooling components. At 4.35 pounds, the bar offers substantial stock for multiple parts from a single length.

This drill rod is suited for job shops, tool rooms, and maintenance shops where custom tooling is produced in-house. The 45/64-inch diameter fits applications requiring a near-three-quarter-inch round bar with tight dimensional tolerances. It is appropriate for both low-volume prototype work and short-run production tooling. Machinists working with manual or CNC lathes and mills will find this diameter useful for turning down to finished punch or reamer dimensions before heat treatment.

Key Features

• O-1 oil hardening tool steel grade for predictable, controlled heat treatment response
• 0.703 inch (45/64 inch) diameter provides near-three-quarter-inch stock with tight tolerance
• 36-inch length supplies sufficient material for multiple tooling blanks per bar
• Oil hardening process minimizes distortion and cracking risk compared to water-hardening grades
• Tool steel composition supports high hardness after quench, suitable for cutting and forming tools

Compatibility

Designed as standard O-1 tool steel drill rod stock for use as raw material in fabricating punches, drill blanks, reamers, and other precision tooling where oil hardening grades are specified.

Installation Notes

Cutting and grinding O-1 tool steel drill rod should be performed by a qualified machinist using appropriate speeds and feeds for tool steel. Hardening requires controlled furnace heating followed by an oil quench — consult published heat treatment data for O-1 before processing. Wear appropriate PPE when cutting, grinding, or heat treating. Handle bar stock with care to avoid surface nicks that can become stress concentrators after hardening.
