Bit Face Shape Selection:

1. Drop Center Bit

Ideal for achieving high penetration rates in soft to medium-hard and fissured rock formations with low to medium air pressures, offering maximum hole deviation control.

2. Concave Face

Perfect for medium-hard and homogeneous rock formations, providing excellent hole deviation control and outstanding flushing capacity.

3. Convex Face

Best suited for high penetration rates in soft to medium-hard rocks with low to medium air pressures. Exceptional resistance to steel wash and reduced load on gauge buttons, though with poorer hole deviation control.

4. Flat Face

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

 Raw Material

Steel:

Premium special alloy steel with high strength, heat resistance, and wearability.

Carbide:
Top-grade tungsten carbides from China for superior performance.
High-quality European tungsten carbide options also available for specific needs.
