Bit Face Shape Selection:

1. Drop Center Bit

Ideal for achieving high penetration rates in soft to medium-hard and fissured rocks. Operates efficiently with low to medium air pressures. Ensures maximum hole deviation control.

2. Concave Face

A versatile bit face for all-around applications in medium-hard, homogeneous rock formations. Offers excellent hole deviation control and impressive flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard rocks with low to medium air pressures. Offers maximum resistance to steel wash, reducing load and wear on gauge buttons, though with limited hole deviation control.

4. Flat Face

Perfect for hard to very hard and abrasive rocks in high air pressure applications. Provides excellent penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel, offering unmatched strength, heat resistance, and wearability.

Carbide
Sourced from China, the finest tungsten carbides are commonly applied for optimal performance.
European tungsten carbide options are also available to meet diverse needs.
