A new and improved offset drive countersink apparatus is provided for connection to a rotary drive source and includes a first driven rotating member connected to the rotary drive source. The first driven rotating member rotates around a first longitudinal axis. A first gear is connected to the first driven rotating member, is driven thereby, and rotates around the first longitudinal axis. The first gear lies in a first plane. A second gear meshes with the first gear and also lies in the first plane. The second gear rotates around a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are offset from each other by a predetermined offset distance in the first plane. A housing receives the first gear and the second gear and supports the first gear and the second gear in the first plane. A countersink tool is connected to the second gear. The countersink tool is driven by the second gear and rotates around the second longitudinal axis at the predetermined offset distance offset from the first driven rotating member. The housing includes a bottom planar portion and a top planar portion that house and support the first gear and the second gear in the first plane. The housing also includes alignment apertures for keeping the first driven rotating member and the first gear in alignment and for keeping the second gear and the countersink tool in alignment.
