Product Description

73mm Downhole motors for mines with superb rock-carrying capacity
The structure of our mining downhole motors is the outer helix with three-pronged structure, which greatly enhances the rock-carrying capacity of the downhole motors, and has received unanimous praise from customers. Moreover, the motor power still maintains a strong torque, which ensures a strong rock-breaking and at the same time enhances the rock-carrying capacity, and it is a reliable tool for drilling in coal mines.
