DTH Bits Shank Identification
Flat front: Spherical buttons
Applications: For drilling in hard and abrasive rock
Flat front: Spherical gauge buttons, Ballistic front buttons.
Applications: For drilling in medium hard to hard and moderately abrasive rock.
Convex front: Ballistic
Applications: For drilling at high penetration rates in non abrasive rock.
Concave front: Ballistic
Applications: For drilling in medium hard, maximum hole deviation control.
Hemispherical button Universal buttons for all rock formation, best suited to hardest and very abrasive rocks formation
Parabolic button (semi-ballistic) Excellent penetration rate, but only suited to medium hard and not-very-abrasive rock formation.
Ballistic buttons Similar to parabolic buttons, used for soft to medium hard and not so abrasive rock formation, excellent in penetration rate
