Bit Face Shape Selection:

1. Drop Center Bit

Engineered for high penetration rates in soft to medium-hard and fissured rock formations. Suitable for low to medium air pressures. Ensures excellent hole deviation control.

2. Concave Face

The versatile choice for medium-hard and homogeneous rock formations. Offers good hole deviation control and excellent flushing capacity.

3. Convex Face

Ideal for high penetration rates in soft to medium-hard rocks with low to medium air pressures. Provides strong resistance to steel wash, reducing load and wear on gauge buttons, though it offers poor hole deviation control.

4. Flat Face

Suitable for hard to very hard and abrasive rock formations with high air pressures. Delivers excellent penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from top-tier special alloy steel with exceptional strength, heat resistance, and durability.

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