Bit Face Shape Selection:

1. Drop Center Bit

Excels in soft to medium-hard and fissured rock formations. Operates efficiently under low to medium air pressures, providing superior hole deviation control.

2. Concave Face

A versatile bit face ideal for medium-hard and homogeneous rock formations. Offers excellent hole deviation control and effective flushing capacity.

3. Convex Face

Perfect for high penetration rates in soft to medium-hard rocks at low to medium air pressures. Resistant to steel wash, reduces load and wear on gauge buttons, but may have poor hole deviation control.

4. Flat Face

Optimal for hard to very hard and abrasive rock formations. Best used with high air pressures, providing good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from premium special alloy steel, renowned for its high strength, heat resistance, and wearability.

Carbide
Utilizes top-tier tungsten carbides sourced from China.
European tungsten carbide options are also available.
