Value Collection O1D316 O-1 Drill Rod 0.12 in Tool Steel

Product Description

The VALUE COLLECTION O1D#316 is an O-1 oil hardening drill rod machined from tool steel and sized to a nominal wire gauge of 31, with an actual diameter of 0.12 inches and an overall length of 36 inches. O-1 tool steel is an oil-hardening, cold-work grade known for its dimensional stability during heat treatment and its ability to hold a sharp, precise edge after hardening and tempering. This rod stock is used by machinists, toolmakers, and die shops to fabricate punches, broaches, dowel pins, and similar precision tooling components that require post-machining heat treatment.

This drill rod is suited to light-duty precision toolmaking applications in job shops, maintenance facilities, and manufacturing environments. Its 0.12-inch diameter corresponds to wire gauge 31, making it a common stock size for small punch blanks, guide pins, and alignment fixtures. Machinists working to close tolerances will find the ground finish and consistent diameter useful for applications where an off-the-shelf diameter eliminates a roughing pass.

Key Features

• O-1 oil hardening tool steel for controlled, predictable heat treatment response
• Ground to 0.12 inches actual diameter, nominal wire gauge 31
• 36-inch length provides workable stock for multiple short blanks from a single rod
• Consistent diameter along the full length supports precision layout and toolmaking
• Oil hardening process minimizes distortion compared to water-hardening grades

Compatibility

Designed as standard O-1 oil hardening drill rod stock for general-purpose toolmaking and machining applications requiring a 0.12-inch diameter ground rod.

Installation Notes

Cutting this rod to length requires a suitable metal cutoff saw, abrasive wheel, or lathe parting tool rated for tool steel. Always wear appropriate eye and hand protection when cutting or grinding tool steel stock. Heat treatment of O-1 tool steel should be performed by a qualified toolmaker or heat treater following established metallurgical procedures for hardening and tempering. Allow the rod to cool to ambient temperature before handling after any thermal operation.
