75mm Single-Tube Diamond Impregnated Core Bit – For Hard Rock Drilling/Deep Sampling/Oil & Gas Applications

  1. High-Strength Impregnated Design – Diamond-impregnated segments ensure efficient cutting in extremely hard formations (e.g., granite, basalt) with extended bit life.

  2. Precision Deep Sampling – 75mm standard diameter with single-tube structure optimizes core recovery, ideal for oil, gas exploration, and geological research.

  3. Heat & Wear Resistant – Special matrix formula and sintering process withstand high RPM and heavy loads, ensuring stability in tunneling and underground projects.

  4. Multi-Scenario Compatibility – Compatible with mainstream drilling rigs for mining, hydroengineering, and vertical/horizontal boring in complex strata.

  5. Cost-Effective Performance – Low wear rate and high ROP (rate of penetration) reduce overall operational costs, making it ideal for deep hard rock drilling.
