| Bit Face Shape | Introduction |
| Drop Center Face | For high penetration rates in soft to medium hard and fissured rock formations,
Low to medium air pressures. Maximum hole deviation control. |
| Concave Face | The all-round application bit face specifically for medium hard and homogeneous rock formations.
Good hole deviation control and good fishing capacity. |
| Convex Face | For high penetration rates m soft to medium-hard with low to medium air pressures.
It is the most resistance to steel wash. And many reduce the load and wear on the gauge buttons.
But poor hole deviation control. |
| Double Gauge Face | This kind face shape is suitable for fast penetration rates in medium to hard rock formations.
Designed for high air pressures and good resistance to steel wash step gauge bit. |
| Flat Face Bit | This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressure.
Good penetration rates are resistance to steel wash. |
