Bit Face Shape Selection:

1. Drop Center Bit

Designed for high penetration rates in soft to medium-hard and fissured rock formations. Suitable for low to medium air pressures, providing maximum hole deviation control.

2. Concave Face

An all-around application bit face specifically for medium-hard and homogeneous rock formations. It offers good hole deviation control and effective flushing capacity.

3. Convex Face

Ideal for high penetration rates in soft to medium-hard rock formations with low to medium air pressures. It's most resistant to steel wash and may reduce load and wear on gauge buttons, though with less effective hole deviation control.

4. Flat Face

Suitable for hard to very hard and abrasive rock formations in high air pressure applications. Offers good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Utilizing first-class special alloy steel with high strength, excellent heat resistance, and superior wearability.

Carbide
Commonly applied best tungsten carbides sourced from China, ensuring top-notch quality.
Additionally, European tungsten carbide options are available for specialized requirements.
