Oil Hard Drill Rod O1 3/8″ Grainger Approved Tungsten Rod 36″ Length

Description

Product Overview

The Oil Hard Drill Rod O1 3/8″ is engineered to meet the rigorous demands of modern industrial machining and drilling operations. Manufactured under the Grainger Approved program, this rod combines a premium UNS T31501 steel alloy with the O1 oil‑hardening process, delivering a hardness level that exceeds typical drill rod specifications. At a full 36″ length, the rod provides ample reach for deep‑hole drilling while maintaining a tight tolerance of +0.125″/-.000″, ensuring dimensional stability throughout its service life. The 3/8″ fractional size aligns with standard tooling, allowing seamless integration into existing equipment without the need for adapters. Its tungsten‑enhanced composition offers superior wear resistance, reducing the frequency of replacements and minimizing downtime on the shop floor.

Usage

Designed for a broad range of applications, this drill rod excels in environments where precision and durability are paramount. It is ideally suited for heavy‑duty drilling in metal fabrication, aerospace component manufacturing, and high‑stress tooling setups. The rod’s oil‑hardening treatment provides excellent performance when used with lubricants and cutting fluids, extending tool life and improving chip evacuation. Whether you are drilling through hardened steel, alloyed titanium, or composite materials, the consistent hardness and dimensional accuracy of the O1 grade ensure clean, straight holes with minimal deviation. The 36″ length also makes it a preferred choice for deep‑bore operations, such as creating pilot holes for large‑diameter taps or installing threaded inserts in thick workpieces.

FAQ

What does the O1 oil‑hardening process entail?

The O1 oil‑hardening process involves heating the steel to a specific temperature and then quenching it in oil. This treatment increases the material’s hardness and wear resistance, making the drill rod suitable for demanding drilling tasks.

Can this drill rod be used with standard cutting fluids?

Yes, the rod is compatible with a wide range of cutting fluids and lubricants. Using appropriate fluids helps reduce friction, improve chip evacuation, and extend the life of the rod.

What is the recommended storage condition for the drill rod?

Store the rod in a dry, climate‑controlled environment to prevent corrosion. Keeping it in its original packaging until use is also advisable to maintain its surface integrity.

Is the 36″ length suitable for all drilling depths?

The 36″ length is ideal for deep‑hole drilling up to the full length of the rod. For shallower applications, the rod can be trimmed to the required size while preserving its hardness profile.

How does Grainger ensure the quality of this product?

Grainger follows rigorous inspection protocols, including dimensional checks, hardness testing, and material certification against industry standards. Each rod is tracked through a documented batch system to guarantee consistency and traceability.
