Bit Face Shape Selection:

1. Drop Center Bit

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

2. Concave Face

Versatile bit face ideal for medium hard and homogeneous rock formations. Provides 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. Offers excellent resistance to steel wash, reducing wear on gauge buttons but may have poor hole deviation control.

4. Flat Face

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

 Raw Material

Steel:

Crafted from first-class special alloy steel, offering high strength, heat resistance, and wearability for demanding applications.

Carbide
We use the finest tungsten carbide from China, renowned for its quality and performance.
Tungsten carbide from Europe is also available, providing additional options for exceptional durability and efficiency.
