All Adtech Drilling Motors are specifically designed for the Horizontal Boring Industry.
The 6 3⁄4” 7-8 Lobe Motor has a bearing section that is 7” - 7 1⁄4” OD. This special design allows for stronger bearings, a heavy duty connecting rod, and an "all around" tough tool. This motor is a slower speed, high torque, and requires at least an 8 3⁄4” drill bit due to the oversized bearing section. The maximum recommended drill bit would be an 9 7⁄8”. This tool performs the best in light-medium rock formations.
Each of Adtech's motors have a sealed bearing pack to keep oil on the bearing for a smoother run.
