Bit Face Shape Selection:

1. Drop Center Bit: Engineered for exceptional penetration in softer rock types, providing reliable performance in variable air pressure conditions and minimizing hole deviation.

For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control: Our Drop Center Bits excel in challenging drilling environments, ensuring precision and consistency even in complex geological settings.

2. Concave Face

The all-around application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity: Ideal for balanced drilling, our Concave Face Bits offer enhanced stability and efficient debris removal in a variety of rock conditions.

3. Convex Face

For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control: Our Convex Face Bits are designed for rapid drilling with exceptional durability, perfect for maintaining performance while reducing wear.

4. Flat Face

This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash: Flat Face Bits offer unmatched resilience in tough drilling scenarios, delivering excellent penetration and enduring the harshest conditions.

 Raw Material

Steel:

first class special alloy steel with high strength, heat resistance and wearable: Our alloy steel is the pinnacle of strength and endurance, engineered to withstand the most extreme conditions, ensuring prolonged service life and reliability.

Carbide
The best tungsten carbides from China are commonly applied: We harness superior Chinese tungsten carbide to guarantee exceptional hardness and wear resistance, enhancing the performance of our drilling tools.
Tungsten carbide from European is also available: European tungsten carbide options offer premium quality for discerning customers, ensuring maximum durability and performance under demanding conditions.
