Value Collection M1D136 O-1 Drill Rod 13mm 36 Inch

Product Description

The VALUE COLLECTION M1D136 is an O-1 oil hardening drill rod machined from tool steel to a diameter of 13 millimeters (0.512 inches) and cut to an overall length of 36 inches. Drill rod in the O-1 grade is valued in tool and die, machinist, and fabrication work for its tight dimensional tolerances, smooth ground finish, and consistent response to oil hardening heat treatment. This stock is used to produce punches, dies, pins, reamers, and other precision tooling components where dimensional accuracy before and after hardening is critical. Machinists, toolmakers, and metalworking shops are the primary users of this material.

This drill rod is suited for job-shop and production toolroom applications where a ground, ready-to-machine O-1 bar is needed. At 36 inches in length and 13mm in diameter, it provides enough material for multiple short tooling blanks from a single piece. It is appropriate for light to medium tooling applications where O-1 oil hardening steel meets hardness and wear requirements. No welding, casting, or powder metal processes are involved — this is a solid, wrought tool steel bar.

Key Features

• O-1 oil hardening tool steel grade for predictable heat treatment response
• 13mm (0.512 inch) diameter with precision ground finish for close-tolerance work
• 36-inch overall length provides multiple tooling blanks from one piece
• Ground surface minimizes additional stock removal before use
• Solid wrought construction throughout — no voids or laminations

Compatibility

Designed as a general-purpose O-1 tool steel drill rod for use in toolroom, die shop, and precision machining applications requiring an oil hardening bar stock in the 13mm diameter range.

Installation Notes

Cutting this rod requires carbide or cobalt tooling appropriate for tool steel stock. Heat treatment to harden O-1 steel should be performed by a qualified heat treater following established time and temperature procedures for the O-1 grade. Wear appropriate personal protective equipment when cutting, grinding, or handling bar stock. Always secure bar stock in a vise or fixture before machining to prevent movement.
