Single cone little bit is a variety of deceleration bit, which is the speed of cone is smaller than the velocity of drill, mainly disorderly reducing damaged rock. It is suited for old effectively sidetracking and deepening the trim hole drilling operation below large rotary speed and drilling pressure. 

1. Its application discipline is vast, not only ideal for facet drilling, and can be utilized in deep nicely. 

two. Operate torque is reduced than PDC bit in the same drilling pressure and development issue. It can minimize the little dimensions hole enlargement buckling problems, so that avoid down hole incidents. 

3. One cone bit has positive aspects of each 3 cone little bit and PDC bit, and make up the drawbacks of each. It is much more suited for big plastic development than 3 cone bit, also can be utilized to difficult interlayer which PDC bit can not deal with other intricate development. 

four. It can comprehend large pace and specific drilling with down gap motor.
