Single cone bit is a sort of deceleration little bit, which is the speed of cone is smaller sized than the pace of drill, primarily disorderly reducing broken rock. It is suitable for aged properly sidetracking and deepening the slender hole drilling operation underneath high rotary speed and drilling strain. 

one. Its application discipline is extensive, not only suitable for side drilling, and can be utilised in deep nicely. 

two. Function torque is decrease than PDC little bit in the identical drilling stress and formation issue. It can reduce the small size hole enlargement buckling difficulties, so that keep away from down gap mishaps. 

three. One cone little bit has benefits of the two 3 cone little bit and PDC little bit, and make up the drawbacks of the two. It is much more suitable for huge plastic formation than three cone little bit, also can be utilized to challenging interlayer which PDC little bit can not offer with other sophisticated formation. 

four. It can realize high velocity and particular drilling with down hole motor.
