Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration in soft to medium-hard and fissured rock formations. Operates at low to medium air pressures with superior hole deviation control.

2. Concave Face

The versatile choice for medium-hard, homogeneous rock formations. Offers excellent hole deviation control and efficient flushing capacity.

3. Convex Face

Perfect for high penetration in soft to medium-hard rock, withstanding low to medium air pressures. Resistant to steel wash and reduces gauge button wear, though offers limited hole deviation control.

4. Flat Face

Optimal for hard to very hard, abrasive rock formations with high air pressures. Ensures great penetration and resistance to steel wash.

 Raw Material

Steel:

Crafted from premium, special alloy steel offering high strength, heat resistance, and durability.

Carbide
Sourced from the finest Chinese tungsten carbides, renowned for excellence.
European tungsten carbide variants are also procurable, enhancing options.
