Double Tube HQ NQ Impregnated Core Drill Bit for Oil & Gas / Tunneling / Deep Drilling Hard Rock Efficient Sampling

  1. Diamond-Enhanced Durability: Utilizes impregnated diamond matrix technology, specifically designed for hard rock (granite, basalt, etc.), improving wear resistance by 50+% and extending bit lifespan.

  2. Double Tube High-Efficiency Coring: Inner and outer tube synergy ensures high core recovery (≥95%), delivering uncontaminated deep samples for scientific exploration and resource evaluation.

  3. Multi-Scenario Adaptability: Ideal for harsh environments such as oil & gas wells, tunnel boring, and underground construction, withstanding high impact and extreme pressure.

  4. Optimized Chip Removal: Helical waterways and high-flow grooves enable fast cuttings removal, reducing jamming risks and improving drilling efficiency.

  5. Customizable Specifications: Available in multiple diameters (75-150mm) and thread connections, compatible with mainstream rigs for flexible depth requirements.
