Bit Face Shape Selection:

1. Drop Center Bit

Optimized for high penetration rates in soft to medium-hard, fissured rock formations. Ideal for low to medium air pressures, ensuring maximum control of hole deviation.

2. Concave Face

An all-purpose bit face, perfect for medium-hard, homogeneous rock formations. Offers excellent hole deviation control and superior flushing capacity.

3. Convex Face

Designed for high penetration in soft to medium-hard rock with low to medium air pressures. Most resistant to steel wash, reducing load and wear on gauge buttons, albeit with reduced hole deviation control.

4. Flat Face

Ideal for hard to very hard, abrasive rock formations with high air pressures. Delivers good penetration rates and superior resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel, offering high strength, excellent heat resistance, and superior wearability for demanding conditions.

Carbide
We incorporate the finest tungsten carbides from China, known for their exceptional quality and performance.
In addition to Chinese sources, premium tungsten carbide from Europe is also available, offering you unparalleled quality and choice.
