5. Face designs include flat, concave, and convex to enhance drilling efficiency.
6. Durable button options: spherical and ballistic, tailored for maximum performance.

Features:
1. Unmatched reliability and longevity, minimizing unexpected breakages throughout its service life.
2. Superior flushing effect ensures a high drilling rate and operational efficiency.
3. Comprehensive quality warranty and compensation policies for assured satisfaction.
4. Thoughtfully engineered designs for optimal functionality.
5. Exceptional penetration rates to enhance productivity.

Bit Face Shape Selection:

1. Drop Center Bit

Achieves high penetration rates in soft to medium-hard and fissured rock formations with low to medium air pressures. Offers maximum hole deviation control.

2. Concave Face

Ideal for medium-hard and homogeneous rock formations. Ensures excellent hole deviation control and superior flushing capacity.

3. Convex Face

Promotes high penetration rates in soft to medium-hard formations with low to medium air pressures. Most resistant to steel wash, reducing load and wear on gauge buttons, but offers less hole deviation control.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations with high air pressures. Delivers impressive penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from premium first-class special alloy steel for superior strength, heat resistance, and wearability.

Carbide
Utilizes top-grade tungsten carbides sourced from China for reliable performance.
European-sourced tungsten carbide options are also available for enhanced durability.
