Features:
1. Exceptional quality and long-lasting durability with minimal breakage over the service life.
2. Optimal flushing effect ensures high drilling efficiency.
3. Comprehensive quality warranty and compensation policies.
4. Thoughtfully engineered designs for superior performance.
5. High penetration rates for efficient drilling.

Bit Face Shape Selection:

1. Drop Center Bit

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

2. Concave Face

Versatile design suitable for medium-hard, homogeneous rock formations. Excellent hole deviation control and effective flushing capacity.

3. Convex Face

Perfect 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. However, it provides less control over hole deviation.

4. Flat Face

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

 Raw Material

Steel:

Crafted from premium special alloy steel known for its high strength, excellent heat resistance, and wearability.

Carbide
Utilizes top-quality tungsten carbides sourced from China.
European tungsten carbide options are also available.
