Solitary cone bit is a kind of deceleration little bit, which is the pace of cone is smaller sized than the velocity of drill, mostly disorderly chopping damaged rock. It is appropriate for outdated effectively sidetracking and deepening the slim hole drilling procedure underneath large rotary pace and drilling strain. 

1. Its software field is extensive, not only suited for aspect drilling, and can be utilised in deep effectively. 

2. Function torque is lower than PDC bit in the very same drilling stress and development condition. It can decrease the small dimension gap enlargement buckling troubles, so that steer clear of down gap accidents. 

three. Single cone bit has positive aspects of the two three cone little bit and PDC little bit, and make up the negatives of the two. It is a lot more appropriate for massive plastic formation than 3 cone bit, also can be utilized to challenging interlayer which PDC little bit can not offer with other complex development. 

4. It can realize higher speed and unique drilling with down gap motor.
