Value Collection M1D186 O-1 Tool Steel Drill Rod 18mm 36in

Product Description

The VALUE COLLECTION M1D186 is an O-1 oil hardening tool steel drill rod measuring 18mm (0.709 inches) in diameter and 36 inches in length. Drill rod stock in O-1 tool steel is used as precision-ground round bar for making punches, dies, reamers, taps, and other cutting or forming tools. O-1 is a general-purpose oil-hardening grade known for good machinability in the annealed state and good dimensional stability during heat treatment. The rod weighs approximately 4.017 pounds. Machinists and toolmakers select this grade when a balance of wear resistance and ease of hardening is required.

This drill rod is suited for job shops, tool-and-die operations, and maintenance machining environments where custom tooling is fabricated in-house. At 18mm diameter and 36 inches in length, the bar can be cut to yield multiple blanks for small tooling components. It is commonly worked on lathes, mills, and surface grinders before hardening and tempering to final service hardness.

Key Features

• O-1 oil hardening tool steel grade — good machinability before heat treat and stable dimensions after quench
• 18mm (0.709 inch) diameter precision-ground round stock
• 36 inches overall length provides multiple blanks per bar
• Suitable for fabricating punches, dies, reamers, gauges, and similar tooling
• Single-piece quantity — no multi-piece minimum required

Compatibility

Designed as a general-purpose O-1 oil hardening drill rod blank compatible with standard tool-and-die, machining, and toolmaking applications requiring an 18mm diameter round stock.

Installation Notes

Cutting and machining of tool steel drill rod should be performed by qualified machinists using appropriate speeds, feeds, and cutting fluids for tool steel. Hardening and tempering operations require controlled furnace equipment and should follow established heat-treatment procedures for O-1 tool steel. Eye protection, appropriate guarding, and chip-control measures are required during all machining operations. Handle bar stock safely to avoid contact with sharp ends or edges.
