HQ Backend Assembly point

HQ Backend Assembly – Heavy-Duty Core Barrel Component for Precision Drilling

The HQ Backend Assembly is a critical component in the core barrel assembly system, designed to connect the drill string with the inner tube assembly in HQ-size core drilling operations. Engineered for hard rock exploration, geotechnical investigation, and mineral coring, this backend ensures precise alignment, smooth inner tube rotation, and long-lasting performance in rugged field environments.

Manufactured from high-strength alloy steel and machined to tight tolerances, our HQ Backend Assembly offers reliable coupling, resistance to wear, and compatibility with all standard HQ core barrel systems.
