2. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce theload and wear on the gauge buttons, but poor hole deviation control.
3. Concave Face
The all-around application bit face specifically for medium hard and homogeneous rock formations.
