3. Backed by strict quality warranties and compensation policies.
4. Engineered with thoughtful and practical designs.
5. High penetration capabilities for efficient drilling.

Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium-hard, fissured rock formations. Operates under low to medium air pressures with excellent hole deviation control.

2. Concave Face

Perfect for all-around application in medium-hard, homogeneous rock formations. Offers good hole deviation control and excellent flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard formations under low to medium air pressures. Highly resistant to steel wash, reducing load and wear on gauge buttons, but offers poor hole deviation control.

4. Flat Face

Best suited for hard to very hard, abrasive rock formations under high air pressures. Provides excellent penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel with exceptional strength, heat resistance, and durability.

Carbide
Commonly utilizes top-grade tungsten carbides sourced from China.
High-quality tungsten carbide from Europe is also available.
