Bit Face Shape Selection:

1. Drop Center Bit

Excels in soft to medium hard, fissured rock formations with low to medium air pressures. Ensures maximum hole deviation control.

2. Concave Face

An all-rounder bit face ideal for medium hard, homogeneous rock formations. Offers good hole deviation control and excellent flushing capacity.

3. Convex Face

Ideal for high penetration in soft to medium-hard rock with low to medium air pressures. Superior resistance to steel wash, reducing gauge button wear, albeit with lower hole deviation control.

4. Flat Face

Perfect for hard to very hard, abrasive rock with high air pressures. Ensures good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel known for its high strength, heat resistance, and wearability.

Carbide
We utilize the finest tungsten carbides from China, known for superior performance.
European tungsten carbide options are also available for specialized needs.
