Single cone little bit is a sort of deceleration bit, which is the pace of cone is smaller sized than the speed of drill, mainly disorderly slicing damaged rock. It is ideal for old properly sidetracking and deepening the trim hole drilling procedure beneath substantial rotary speed and drilling strain. 

one. Its application area is wide, not only ideal for facet drilling, and can be used in deep effectively. 

2. Work torque is reduce than PDC bit in the exact same drilling force and development issue. It can minimize the small dimensions hole enlargement buckling troubles, so that steer clear of down gap accidents. 

three. Single cone bit has positive aspects of equally 3 cone bit and PDC bit, and make up the down sides of each. It is more suitable for massive plastic development than a few cone little bit, also can be utilized to difficult interlayer which PDC little bit can not offer with other complex development. 

four. It can comprehend large velocity and particular drilling with down hole motor.
