Different face style makes DTH bits suitable for various rock conditions.
Flat face: This is an universal design, especially for hard and abrasive rock formation. So typically, flat face with hemi-spherical buttons design is the most popular choice.
Convex face: A classic design for soft to medium hard rock formation which is not so abrasive. This design have very excellent penetration rate but poor in hole deviation if rocks are hard.
Concave face: Medium hard to hard rock formations which is less abrasive and fractured. Especially for deep hole drilling, excellent control over hole deviation.
