Abstract
A drill assembly is provided having a main housing. A tool mount housing is rotatably engaged to the main housing. An air motor is mounted within the main housing and includes an air motor drive shaft. The air motor drive shaft has an upper sun gear attached to it. The air motor drive shaft and upper sun gear are positioned within a first stage ring gear within the main housing. A second stage ring gear is similarly positioned within the tool mount housing. A plurality of planet gears is positioned in between the upper sun gear and the first and second ring gears. When the upper sun gear is rotated, the planet gears are rotated around the first stage ring gear. The rotation of the planet gears rotates tool mount housing by engaging the second stage ring gear.
