It is mainly used for DTH drill bit edge teeth, suitable for very hard rocks with strong abrasivity.
Parabolic tooth:
It is mainly used in DTH drill bit side and middle teeth, suitable for rocks with medium and hard wear.
Warhead tooth:
It is mainly used in DTH drill bit middle teeth, suitable for abrasive medium hardness medium rocks. The soft rock can also be made edge teeth.
Sharp tooth:
Mainly used in DTH drill bit middle teeth, suitable for soft rocks with high drilling speed and low tooth fracture rate.
