The Advantages of single cone bit

 1. Single cone bit is a bit slow, that cone drill bit of speed than the speed of smaller, mainly chaotic cutting rock, suitable for high-speed, high pressure drilling wells sidetracking the old, old wells deepened so slim hole drilling.Applications more widely applicable not only to lateral drilling, and can be used in deep wells. 

2. Working torque than the PDC drill bit in the same conditions of pressure and lower strata can reduce the problem of small size drill expansion button to avoid mine accidents.

3. Single cone bit with both three-cone bit and PDC bit of advantage, there is a difference between the two Surrounded by a shortage of more than three-cone bit more suitable for large plastic formation, but also can be applied to PDC bit difficult to deal with hard interlayer, and other complex formations.
4. With the downhole drill motor to achieve high speed and special drilling needs.
5. Size: various sizes 5 7/8"-17 1/2"
