Bit Face Shape Selection:

1. Drop Center Bit

Engineered for high penetration rates in soft to medium-hard and fissured rocks, using low to medium air pressures. Ensures optimal hole deviation control.

2. Concave Face

Versatile and suitable for medium-hard, homogeneous rock formations. Offers excellent hole deviation control and superior flushing capacity.

3. Convex Face

Ideal for high penetration in soft to medium-hard rocks at low to medium air pressures. Provides resistance to steel wash, reducing wear on gauge buttons, though with less hole deviation control.

4. Flat Face

Perfect for hard to very hard and abrasive rocks, suitable for high air pressure applications. Ensures good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class, high-strength special alloy steel, offering superior heat resistance and durability.

Carbide
We utilize the finest tungsten carbides from China, known for their reliability and performance.
European tungsten carbide is also available for those seeking premium quality.
