The advantages of screw drilling

Screw drilling tool is a kind of positive displacement bottom-hole power drilling tool, which converts the hydraulic energy of drilling circulation washing medium into the mechanical energy of rotating bit crushing rock. It is widely used in the drilling construction of vertical, directional, horizontal and secondary Wells.

The screw drill is mainly divided into two types according to the nature of the rock stratum it encounters

High torque and high speed screw drilling tool, suitable for rock drilling

Conventional torque high speed screw drill is suitable for coal seam drilling.
