Derun drilling motor is a positive displacement motor. High pressure drilling fluid flows into the drilling motors, thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling.
Derun produces lz73, lz89, lz95, lz102, lz120, lz127, lz146, lz165, lz172, lz185, lz197, lz203, lz216, lz244, lz286 and other types of drilling motors. They are for drilling diameter of 88.9-660mm. Derun also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties.

Rock bit is the most popular one in use. When working, the cogging touch the bottom alternately, breaking torque and the contact area both are small, thus the unit pressure is high, so it can penetrate into the layer easily, the length of the blades is longer, which can reduce the abrasion. The rock bit can adapt to a variety of formations from soft to hand.
