6'' 61/2'' 6 3/4'' steel tooth  mill tooth tricone bits

 

 

 

 

Product Description

 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.
