All Adtech Drilling Motors are specifically designed for the Horizontal Boring Industry.
The 3 3⁄4” 5-6 Lobe Motor is a heavy duty, small-medium drilling motor. However, the actual OD of the bearing pack on this motor is 4” - 4 1⁄4”. Adtech designed the same OD on the stator tube. Normally the stator tube would have wall thickness of 1⁄4”. The stator tube is 4” OD and the walls are a beefy 1⁄2” thick. This means stronger threads and less breakage of the motor. The 3 3⁄4" 5-6 lobe design is a medium range speed with medium torque. This motor is used for light to medium hard rock. For harder rock formations, see the 3 3⁄4” 9-10 Drilling Motor.
Each of Adtech's motors have a sealed bearing pack to keep oil on the bearing for a smoother run.
