As with all our tools, it eliminates the need for casing string rotation. A positive displacement motor-powered reamer, it has the benefit of low to mid speed and high torque.
The disposable motor enables the final string to be landed at Target Depth, and also delivers the ability to drill new formation at Target Depth.
Our motorized shoe reamer is the best tool when high torque tough reaming is required through the most challenging hole intervals. It offers exceptional performance with more robust strings.
