One cone bit is a type 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 It is suited for outdated effectively sidetracking and deepening the slender hole drilling operation beneath large rotary velocity and drilling strain. 

1. Its software field is broad, not only appropriate for facet drilling, and can be utilized in deep nicely. 

2. Function torque is lower than PDC bit in the same drilling strain and development situation. It can lessen the tiny dimension hole expansion buckling troubles, so that keep away from down gap mishaps. 

3. Single cone bit has advantages of both 3 cone little bit and PDC little bit, and make up the negatives of each. It is a lot more ideal for massive plastic development than a few cone bit, also can be used to tough interlayer which PDC little bit can not offer with other complicated development. 

four. It can understand high velocity and unique drilling with down hole motor.
