Bit Face Shape Selection:

1. Drop Center Bit

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

2. Concave Face

Ideal for all-around applications, particularly in medium-hard and homogeneous rock formations. Offers good hole deviation control and superior flushing capacity.

3. Convex Face

Optimized for high penetration rates in soft to medium-hard rocks with low to medium air pressures. Provides strong resistance to steel wash and minimizes gauge button wear, though with less hole deviation control.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations, especially under high air pressures. Delivers great penetration rates and 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 top-grade tungsten carbides from China, renowned for their quality and reliability.
European tungsten carbide options are also available, ensuring flexibility.
