Main structure features of cone bit

1  It can be used widely,not only for side tracking,but also for deep hole drilling.

2  Working torque is lower than that of PDC bit under the same WOB and formation conditions,thread expanding problem normally encountered with small size drilling tools can be reduced and consequently,the downhole accident is avoided.

3  By combining advantages of both tricone and PDC bits and eliminating deficiencies of the both, the single cone bit is more suitable for drilling highly piastic formations than tricone bit, and more suitable for drilling tough formations with hard stringers and other complicated formations than PDC.

4  Simple structure,large bearing clearance,high reliability,and the bit is easy to be small sized.
