Bit Face Shape Selection:

1. Drop Center Bit

Ideal for achieving high penetration rates in soft to medium hard and fissured rock formations. Functions well under low to medium air pressures, providing excellent hole deviation control.

2. Concave Face

A versatile bit face suitable for medium hard and homogeneous rock formations, offering superb hole deviation control and efficient flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard formations with low to medium air pressures. Offers superior resistance to steel wash, reducing load and wear on gauge buttons, albeit with less hole deviation control.

4. Flat Face

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

 Raw Material

Steel:

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

Carbide
Utilizes superior tungsten carbides sourced from China, renowned for their robust performance.
European tungsten carbides are also available, offering premium quality options.
