description	A downhole tool includes at least a pilot section, a first expansion section, and a second expansion section. The pilot section has a plurality of cutting elements to cut a pilot hole. Each of the expansion sections has a plurality of cutting elements to successively expand the pilot hole to achieve a final wellbore radius. The pilot section, first expansion section, and second expansion section each have one or more stabilizer pads on respective gages to stabilize the downhole tool during wellbore creation.
