1. A machining tool, comprising:
a body that extends along a longitudinal axis about which the machining tool is intended to be set in relative rotation with respect to a part to be machined; and
at least one machining member secured to the body;
wherein the body comprises:
a central tubular portion forming a duct centered on the longitudinal axis;
a peripheral tubular portion that is coaxial with the central tubular portion and surrounds the central tubular portion;
a first machining stage having a first arm and a second arm that extend on either side of the central tubular portion, the first arm and the second arm each having a machining member at the end thereof, the first arm and the second arm each being integral with the central tubular portion and the peripheral tubular portion; and
a baseplate connecting the central tubular portion and the peripheral tubular portion, this baseplate having means for attachment to a machine-tool spindle; and
wherein the peripheral tubular portion comprises at least one linking arch connecting the first arm and the second arm and bypassing the central tubular portion.
