Single cone bit is a sort of deceleration bit, which is the pace of cone is scaled-down than the velocity of drill, largely disorderly reducing damaged rock. It is suited for outdated effectively sidetracking and deepening the slender gap drilling procedure beneath higher rotary pace and drilling strain. 

1. Its application area is extensive, not only appropriate for aspect drilling, and can be employed in deep properly. 

two. Work torque is reduce than PDC bit in the very same drilling pressure and development condition. It can decrease the modest dimensions gap enlargement buckling troubles, so that stay away from down hole accidents. 

three. Single cone bit has rewards of each three cone bit and PDC bit, and make up the down sides of equally. It is a lot more suitable for huge plastic formation than three cone little bit, also can be applied to challenging interlayer which PDC little bit can not deal with other complex development. 

four. It can realize high speed and unique drilling with down gap motor.
