Bit Face Shape Selection:

1. Drop Center Bit

Designed for achieving high penetration rates in soft to medium-hard and fissured rock formations. Optimized for low to medium air pressures with excellent hole deviation control.

2. Concave Face

This all-around bit face excels in medium hard and homogeneous rock formations, providing good hole deviation control and efficient flushing capacity.

3. Convex Face

Perfect for high penetration rates in soft to medium-hard conditions. Offers resistance to steel wash and may reduce load/wear on gauge buttons, though with less control over hole deviation.

4. Flat Face

Ideal for tackling hard to very hard and abrasive rock formations using high air pressures. Provides strong penetration rates and resistance to steel wash for durable performance.

 Raw Material

Steel:

Utilizes first-class special alloy steel renowned for its exceptional strength, heat resistance, and wearability.

Carbide
Employing the finest tungsten carbides from China for superior drilling outcomes.
Offers the option of European tungsten carbide for enhanced performance and reliability.
