Value Collection O1D146 O-1 Tool Steel Drill Rod 0.18in

Product Description

The VALUE COLLECTION O1D#146 is an O-1 oil hardening tool steel drill rod measuring 0.18 inches in diameter and 36 inches in length. O-1 tool steel is a general-purpose, oil-hardening grade prized for its machinability in the annealed state and its ability to achieve high surface hardness after heat treatment. Drill rod in this profile is supplied in a precision-ground, round cross-section and serves as raw stock for fabricating punches, dies, reamers, taps, dowel pins, and other close-tolerance tooling components. Machinists, tool-and-die makers, and maintenance professionals stock this material as a standard shop supply.

This drill rod is suited for toolroom, maintenance, and light manufacturing environments where small-diameter precision stock is required. The 0.18-inch diameter places it in the fine-gauge range, making it appropriate for applications such as small punch blanks, alignment pins, custom drill fabrication, and fixture components. It is sold as individual 36-inch lengths, making it practical for prototyping or low-volume tooling work where full bar stock is not needed.

Key Features

• O-1 oil hardening tool steel grade — good machinability before hardening, high hardness after quench
• Precision-ground round stock ensures dimensional consistency along the full 36-inch length
• 0.18-inch diameter suits fine-gauge punch, pin, and small-tool applications
• 36-inch length provides flexible cut-to-size stock for multiple small components from a single piece
• Supplied as individual pieces with no minimum quantity requirement beyond one unit

Compatibility

Designed as a general-purpose O-1 oil hardening drill rod for toolroom and maintenance applications requiring precision-ground, small-diameter round steel stock.

Installation Notes

Cutting and machining of tool steel drill rod should be performed with appropriate metalworking equipment and personal protective equipment including eye and hand protection. When heat treating O-1 steel, follow established oil-quenching procedures for this grade, as improper quench medium or temperature control can result in cracking or inadequate hardness. All grinding, cutting, and heat-treating operations should comply with applicable shop safety standards and local codes. Allow parts to fully cool and inspect for cracks before placing hardened components into service.
