Bit Face Shape Selection:

1. Drop Center Bit

Designed for rapid penetration in soft to medium-hard and fissured rocks, operating effectively under low to medium air pressures. Offers excellent hole deviation control.

2. Concave Face

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

3. Convex Face

Maximizes penetration in soft to medium-hard rocks with low to medium air pressures. Highly resistant to steel wash and reduces wear on gauge buttons, though with limited hole deviation control.

4. Flat Face

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

 Raw Material

Steel:

Crafted from first-class special alloy steel, boasting high strength, heat resistance, and wearability.

Carbide
Utilizes the finest tungsten carbides sourced from China, known for their robustness and performance.
For those seeking premium quality, tungsten carbide from Europe is also an available option.
