5. High penetration. Achieve remarkable depth and speed with our cutting-edge penetration capabilities.

Bit Face Shape Selection:

1. Drop Center Bit. Perfect for dynamic conditions, this bit controls deviation and enhances penetration in varied terrains.

For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control. This ensures precision drilling in challenging environments.

2. Concave Face. Versatile and efficient, this bit is a top choice for all-around applications.

The all-around application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity. This makes it ideal for consistent performance.

3. Convex Face. Built for resilience, it thrives in soft to medium-hard conditions, optimizing drilling speed and durability.

For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistant to steel wash, may reduce the load and wear on the gauge buttons, but poor hole deviation control. Ideal for controlled and efficient operations.

4. Flat Face. Designed for the toughest challenges, excelling in hard and abrasive environments.

This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash. Perfect for high-pressure drilling needs.

 Raw Material

Steel:

First class special alloy steel with high strength, heat resistance and wearability. Our steel sets the standard for endurance in extreme conditions.

Carbide:
The best tungsten carbides from China are commonly applied. These carbides are selected for their exceptional durability and performance.
Tungsten carbide from Europe is also available. European carbides offer alternative excellence, ensuring top-tier results.
