One cone little bit is a variety of deceleration bit, which is the pace of cone is scaled-down than the speed of drill, mainly disorderly cutting broken rock. It is suited for old well sidetracking and deepening the slim gap drilling procedure under large rotary speed and drilling pressure. 

one. Its software subject is wide, not only ideal for side drilling, and can be used in deep effectively. 

two. Function torque is reduced than PDC little bit in the same drilling force and formation problem. It can minimize the small size hole expansion buckling difficulties, so that avoid down gap mishaps. 

three. One cone bit has positive aspects of the two 3 cone bit and PDC bit, and make up the down sides of the two. It is a lot more ideal for massive plastic development than a few cone little bit, also can be used to challenging interlayer which PDC bit can not offer with other complex development. 

4. It can realize substantial pace and special drilling with down hole motor.
