One cone little bit is a type of deceleration bit, which is the speed of cone is scaled-down than the pace of drill, largely disorderly cutting damaged rock. It is suitable for outdated effectively sidetracking and deepening the slim hole drilling procedure under high rotary pace and drilling stress. 

1. Its application area is broad, not only suited for aspect drilling, and can be employed in deep properly. 

two. Operate torque is reduced than PDC little bit in the very same drilling stress and development issue. It can reduce the small size gap growth buckling issues, so that stay away from down hole accidents. 

3. Single cone little bit has positive aspects of both 3 cone bit and PDC little bit, and make up the disadvantages of both. It is far more ideal for huge plastic development than a few cone little bit, also can be applied to challenging interlayer which PDC little bit can not offer with other complicated formation. 

4. It can realize high velocity and unique drilling with down hole motor.
