Product Description

Product Description

75mm 4-Wing PDC Concave Bit (Core Barrel Thread Bit)

High-Performance PDC Drill Bit for Fast & Stable Drilling

Engineered for efficient drilling in medium to hard formations like sedimentary rock, shale, and limestone, this 75mm PDC bit combines a 4-wing concave/convex blade design with high-grade polycrystalline diamond (PDC) cutters for exceptional performance. The unique blade structure improves cuttings removal, minimizes balling, and extends bit life—ideal for core drilling with core barrel threading systems.

Key Features & Benefits:

1. 4-Wing PDC Design – Optimized blade layout for balanced cutting & extended bit life.
2. Concave/Convex Structure – Improves ROP (Rate of Penetration) and minimizes bit balling.

3. High-Quality PDC Cutters – Premium 19mm/13mm cutters for longer wear resistance.

4. Core Barrel Thread (API Standard) – Easy connection with core drilling systems.

5. Wide Applications – Ideal for geotechnical exploration, water well drilling, and mineral coring.
