NQ（NAU) Drill Rod
High quality  alloy steel pipe

Product Description:

NQ Drill Rods for 2000m+ WL Diamond Core Drilling | High-Strength Alloy Steel

Product Overview

Specifically engineered for mining exploration and Wireline (WL) diamond core drilling to depths of 2000 meters and beyond. Manufactured from high-quality alloy steel pipe, these rods offer exceptional concentricity and straightness, ensuring drilling accuracy and efficiency. Fully compliant with DCDMA standards (compatible with BQ, HQ, PQ sizes).

Core Technology & Advantages

Superior Material Strength: Our proprietary Thru-Wall Treatment enhances overall material strength by 140%, significantly improving torsional and tensile performance for ultra-deep hole applications.
Extended Thread Life:
- Box Threads: Specially heat-treated to dramatically increase thread wear resistance.
- Pin Threads: Thread crests are hardened to approximately 55 HRc, effectively preventing "thread jumping" and premature wear, ensuring reliable connections.
Exceptional Geometric Precision: Maintains excellent concentricity and straightness, reducing drill string vibration and eccentric wear to protect the bit and improve core recovery rates.

Exceptional Geometric Precision: Maintains excellent concentricity and straightness, reducing drill string vibration and eccentric wear to protect the bit and improve core recovery rates.

Professional Protective Packaging

Our rods are securely packed in "bundles" for maximum protection during shipping and handling:

Thread Protection: Rigid carton end caps fully cover both box and pin threads, which are pre-lubricated and sealed against corrosion.
Overall Protection: The entire bundle is secured with heavy-duty galvanized square or hexagonal strapping and end caps, providing robust impact and moisture resistance.
