DTH rock drill bits hole diameter: 3", 4", 5", 6", 8"(85mm-305mm)
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.
For high penetration rates in soft to medium-hard with low to medium air pressures. 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.
Ballistic Buttons
Similar to parabolic/semi-ballistic buttons, used for soft to medium hard and not so abrasive rock formation, excellent in penetration rate.
