ABSTRACT:
An inverted motor with a drilling utensil attached to or integrated as part of an outer motor housing that rotates around a fixed non-rotating shaft or tube. The non-rotating shaft or tube is attached to a fixed base and can extend to the end or past the end of the drilling utensil. A rotary motor is positioned between the outer rotating housing and center fixed shaft and imparts force and motion to the housing and drilling utensil. A channel traverses through the length of the shaft or tube to allow fluids or wires to fully or partially bypass the motor.
