1. Concave face
It helps in easy drilling of straight holes into both medium to hard rock. With excellent air flushing ability, it is inclusive of the high rate of penetration.
2. Flat face
It performs the best in case of hard, abrasive, and broken rocks. It is known for its slower rate of penetration than a concave-faced hammer.
