Diamond composite (PDC) bit uses diamond composite as the main cutting element, employing the principle of scraping and shearing for rock crushing. Ideal for drilling in soft to medium hard stratum, it offers superior performance in overcoming incomplete stratum drilling challenges.

• Versatile Application: Suitable for soft to medium hard formations including mudstone, sandstone, and intercalated limestone. Reinforced versions can handle super hard formations.
• Optimized Design: Special cutting structure and straight blade design ensure smooth operation with minimal tool surface swing during sliding.
• High Efficiency: Highly smoothed cutting teeth reduce friction resistance, quickly remove debris, and significantly improve cutting efficiency.
• Enhanced Stability: Unique stability features maintain drill bit stability during operation, minimizing vibration damage from BHA, operation, or formation factors.
