  • Semi-ballistic: Usually for medium hard rocks 
  • Conical: Usually for soft rocks

Head & Skirt Design:

  • Drop center/Standard skirt: Perfect in abrasive formations where there is accelerated button wear or in medium to hard rock when ballistic buttons have a tendency to break.
  • Drop center/Retract skirt: To be used in medium-hard and fissured rock formations, better hole deviation control.
  • Flat front/Standard skirt: Ideal for medium-hard rock when the rock formation causes heavy gauge wear on the bit. Can also be used in very hard and abrasive rock formations.
