2. Excellent flushing effect ensuring a high drilling rate.
3. Comprehensive quality warranty and compensation guidelines.
4. Thoughtfully engineered designs.
5. Enhanced penetration capability.

Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium-hard and fissured rock formations. Operates effectively under low to medium air pressures, offering maximum hole deviation control.

2. Concave Face

A versatile bit face suitable for medium-hard and homogeneous rock formations. Provides good hole deviation control and effective flushing capacity.

3. Convex Face

Optimal for high penetration rates in soft to medium-hard rock with low to medium air pressures. High resistance to steel wash, reducing load and wear on gauge buttons, though with compromised hole deviation control.

4. Flat Face

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

 Raw Material

Steel:

Utilizes first-class special alloy steel characterized by high strength, heat resistance, and wearability.

Carbide
Premium tungsten carbides sourced from China are widely used.
European tungsten carbide options are also available.
