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


3. Convex Face: Offers high penetration rates in soft to medium-hard rock formations with low to medium air pressures. Provides resistance to steel wash but 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.
