Bit Face Shape Selection:

1. Drop Center Bit

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

2. Concave Face

Ideal for medium hard and homogeneous rock formations. This versatile face ensures good hole deviation control and effective flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard rock with low to medium air pressures. It offers superior resistance to steel wash, reducing wear on gauge buttons, though it has lower hole deviation control.

4. Flat Face

Perfect for hard to very hard and abrasive rock formations, especially under high air pressures. Provides good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Constructed from premium-grade special alloy steel, offering high strength, heat resistance, and durability.

Carbide
Utilizes the best tungsten carbides sourced from China, ensuring reliability and performance.
Tungsten carbide from Europe is also available for enhanced quality and durability.
