NQ Spearhead Point for Head Assembly – Precision for Reliable Core Recovery

The NQ Spearhead Point is an essential component of the NQ head assembly, designed to securely engage the inner tube system in wireline core drilling. Precision-engineered from heat-treated alloy steel, this spearhead point ensures consistent locking and proper alignment of the inner tube within the core barrel. It connects seamlessly with the overshot and locking couplings, making it a key element for smooth inner tube retrieval and efficient core recovery. Built to withstand the extreme pressure, torque, and vibration encountered in mineral exploration, geotechnical investigations, and environmental drilling, the NQ spearhead point delivers high strength and durability in demanding conditions. Its accurate fit reduces downtime, improves safety, and maintains the integrity of both equipment and core samples. Compatible with standard NQ double and triple tube core barrel systems, this part is trusted by professional drillers worldwide and is available in both standard and custom configurations to meet specific project requirements.
