Disclosed herein is a rotary cutter for cutting gears, couplings and the like. The rotary cutter comprises a cutter head having an axis of rotation, a centering disc located adjacent to a side of the cutter head and concentric with the axis and a cutter ring, centered by the centering disc, on the cutter head. The centering disc has a tapered outer edge surface that abuts against and is complementary with the tapered surface of the bore of the cutter ring. The cutter ring is centered once the surfaces are complementary. Once centered, the cutter ring is secured to the cutter head. The rotary cutter of the present invention enables the cutter ring to rotate true about the axis of a machine tool.
