The underreamer may include a cutter block that moves from a retracted position to an expanded position. The underreamer is positioned above the stabilizer, and a distance between an outer surface of the cutter block and a central longitudinal axis of the body may be greater than a distance between an outer surface of the blade and the central longitudinal axis when the blade and cutter block are in the expanded positions.
