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 rock is too hard. For high penetration rate in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control. Semi-Ballistic/Parabolic Buttons Excellent penetration rate, but only suited to medium hard and not so very abrasive rock formation.
