4. Thoughtful Designs: Engineered for effectiveness and efficiency.
5. High Penetration: Delivers superior penetration capabilities.

Bit Face Shape Selection:

1. Drop Center Bit

Designed for high penetration rates in soft to medium-hard and fissured rock formations. Suitable for low to medium air pressures, ensuring maximum hole deviation control.

2. Concave Face

An all-around application bit face, ideal for medium-hard and homogeneous rock formations. Offers good hole deviation control and excellent flushing capacity.

3. Convex Face

Perfect for high penetration rates in soft to medium-hard formations with low to medium air pressures. This shape is highly resistant to steel wash, reducing load and wear on gauge buttons, although it offers 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:

Constructed from first-class special alloy steel, known for its high strength, heat resistance, and wearability.

Carbide
Utilizes the finest tungsten carbides available from China.
European tungsten carbides are also available upon request.
