1. Its application area is extensive, not only ideal for side drilling, and can be utilised in deep properly. 

2. Operate torque is reduced than PDC bit in the very same drilling strain and formation problem. It can reduce the tiny dimension gap expansion buckling troubles, so that steer clear of down gap mishaps. 

three. Single cone bit has rewards of the two a few cone little bit and PDC little bit, and make up the negatives of each. It is much more suitable for large plastic formation than a few cone little bit, also can be utilized to tough interlayer which PDC little bit can not deal with other sophisticated development. 

4. It can recognize substantial pace and particular drilling with down hole motor.
