2. Excellent flushing effect to maintain a high drilling rate.
3. Rigorous quality warranty and comprehensive compensation policies.
4. Designed with precision for optimal functionality.
5. Ensures high penetration for efficient drilling operations.

Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium-hard and fissured rock formations. Operates efficiently at low to medium air pressures with excellent hole deviation control.

2. Concave Face

Perfect for all-around application in medium-hard and homogeneous rock formations. Provides good hole deviation control and excellent flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard rock with low to medium air pressures. Highly resistant to steel wash, reducing load and wear on gauge buttons, though it has poor hole deviation control.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations with high air pressures. Offers good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel with high strength, heat resistance, and wearability.

Carbide
Utilizes the finest tungsten carbides from China for superior performance.
European tungsten carbide options are also available for enhanced durability.
