2. Bit Face Shape Selection:

1) Drop Center Bit

----For high penetration rates in soft to medium hard and fissured rock formations.

2) Concave Face

----The all-around application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.

3) 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.
