Bit Face Shape Selection:

1. Drop Center Bit

Ideal for achieving high penetration rates in softer to medium-hard and fissured rock formations. Operates effectively under low to medium air pressures while providing superior control over hole deviation.

2. Concave Face

A versatile bit face specifically suited for medium-hard and homogeneous rock formations, offering excellent hole deviation control and superior flushing capacity.

3. Convex Face

Optimized for high penetration in soft to medium-hard conditions with low to medium air pressures. Known for its resistance to steel wash, it reduces load and wear on gauge buttons, although it offers poor hole deviation control.

4. Flat Face

Perfect for penetrating hard to very hard and abrasive rock formations, especially under high air pressures. It ensures good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from superior special alloy steel known for its high strength, heat resistance, and wearability, ensuring durability and performance.

Carbide
Utilizing China's finest tungsten carbides, renowned for their quality and effectiveness in demanding drilling operations.
For those seeking the finest, we also offer premium tungsten carbide sourced from Europe, providing an edge in performance and reliability.
