Bit Face Shape Selection:

1. Drop Center Bit: Ideal for achieving high penetration rates in soft to medium hard and fissured rock formations. Suitable for low to medium air pressures and provides maximum hole deviation control.


2. Concave Face: The all-around application bit face specifically designed for medium hard and homogeneous rock formations. Offers good hole deviation control and excellent flushing capacity.


3. Convex Face: Provides high penetration rates in soft to medium-hard rock formations with low to medium air pressures. Offers the most resistance to steel wash and reduces load and wear on the gauge buttons. However, it may have poor hole deviation control.


4. Flat Face: Suitable for hard to very hard and abrasive rock formations with high air pressures. Offers good penetration rates and resistance to steel wash.

Choose the right bit face shape based on your specific drilling requirements to achieve optimal results.
