Bit Face Shape Selection:

1. Drop Center Bit

Optimized for high penetration rates in soft to medium-hard and fissured rock formations. Operates effectively at low to medium air pressures with superb hole deviation control.

2. Concave Face

A versatile choice for medium-hard and homogeneous rock formations. Provides excellent hole deviation control and efficient flushing capacity.

3. Convex Face

Ideal for high penetration rates in soft to medium-hard rock at low to medium air pressures. Offers the best resistance to steel wash, reducing load and wear on gauge buttons, though with less effective hole deviation control.

4. Flat Face

Perfect for hard to very hard and abrasive rock formations, especially in high air pressure applications. Ensures good penetration rates and steel wash resistance.

 Raw Material

Steel:

Crafted from premium special alloy steel known for its high strength, heat resistance, and durability.

Carbide
We use the finest tungsten carbide sourced from China.
European tungsten carbide options are also available.
