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 the 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.

Dome/Hemispherical Buttons

Universal buttons for all rock formation, best suited to hardest and very abrasive rock formation.

Semi-Ballistic/Parabolic Buttons

Excellent penetration rate, but only suited to medium hard and not so very abrasive rock formation.
