DTH Bits Shank Identification
DTH bits head design and selection
  • 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.

Button shapes selection
  • 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
