Bit Face Shape Selection:

1. Drop Center Bit

Ideal for achieving high penetration rates in soft to medium-hard and fissured rock formations. Optimized for low to medium air pressures and excellent hole deviation control.

2. Concave Face

The versatile choice for medium-hard and homogeneous rock formations, offering good hole deviation control and effective flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard formations with low to medium air pressures. Highly resistant to steel wash, reduces load and wear on gauge buttons. Note: Offers poor hole deviation control.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations in high air pressure applications. Delivers excellent penetration rates and strong resistance to steel wash.

 Raw Material

Steel:

Manufactured from first-class special alloy steel, known for its high strength, heat resistance, and durability.

Carbide
Utilizes superior tungsten carbide sourced from China.
European-sourced tungsten carbide is also an available option.
