Flat Face

An universal design, especially for hard and abrasive rock formation. So 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 and resistance to steel wash.
