 | 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. |
Mill tooth Tricone bit
Mill tooth Tricone bit Advantages
1. Optimized structure design of cutter shape is thickened hardfacing on surface and crest of cutters to enhance aggressiveness for cutters.
2. Enhanced hardfacing on leading edge and trailing edge of cutters improve wear-resistance of cutters.
3. New welding material is used to enhance further wear resistance of cutters.
4. Seal types of this bit are selected based on drilling applications. Default type of the bearing is rubber Oring seal.
