Flat Face Bit
This is an universal design, especially for hard and abrasive rock formation. Typically, flat face with hemispherical buttons design is the most popular choice.
This kind of face shape is suitable for hard to very hard and abrasive rock formations in application with high air pressure. Good penetration rates an resistance to steel wash.
In general, the larger the number of gauge buttons the better overall performance, especially in hard rock.
