6 3/4" 7:8 2.9 Stage
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.
Stator and Rotor sizes are subject to change at the discretion of Adtech. Power section specifications may vary due to environmental conditions. Operation of power section above the maximum recommended differential pressure will result in a decrease of stator life and performance.
