Solitary cone little bit is a kind of deceleration bit, which is the pace of cone is smaller than the speed of drill, primarily disorderly cutting damaged rock. It is appropriate for old well sidetracking and deepening the slim gap drilling procedure below substantial rotary pace and drilling strain. 

1. Its application area is extensive, not only suited for facet drilling, and can be employed in deep well. 

two. Work torque is reduced than PDC little bit in the same drilling strain and formation issue. It can decrease the tiny measurement hole growth buckling difficulties, so that stay away from down gap mishaps. 

3. Single cone little bit has advantages of equally 3 cone little bit and PDC little bit, and make up the disadvantages of the two. It is much more appropriate for large plastic formation than a few cone bit, also can be used to hard interlayer which PDC bit can not offer with other intricate development. 

4. It can recognize higher velocity and special drilling with down gap motor.
