K Hard plastic formation cutting structure
Unique designing parameters and wider insert crest enlarge rock-breaking volume on bottom hole and increase bottom hole coverage. At the same time, shear sliding distance of inserts at bottom hole is made larger and ROP of the bit in hard plastic formation is increased.
X Convex crested wedge compact
Convex crested wedge compact is with the features of high effectively cutting ability and strong anti-breaking ability, which can increase ROP and improve service lite of bit effectively it's suitable for formations from
medium soft to medium hard.
Y Conical spherical compact
Main cutters of bit are conical spherical compacts, which are suitable for drilling in hard brittle formations.
