Turbdrill
Turbodril has a high speed, torque,directly to provide high mechanical power, to achieve the best penetration rate. Turbine + gestation sac diamond bit of high-speed shearing action, when drilling in the plastic mud shale, even if there is a big positive pressure difference will not affect the drilling rate
Due to the low ground drill speed, reduce wear casing drill pipe and borehole drilling tools.
Turbodrill level low vibration, can reduce the damage of bit and bottom hole drilling tools.
Drill all the damaged are concentrated within the bearing section, maintenance is convenient.
Drill with flexible elbow, used in horizontal well drilling.
