  • Patent number: 9352405
    Abstract: The reaming tool comprises a cutting part having a peripherally arranged reaming cutter which, upon rotation about a center axis of the reaming tool, defines a cutting circle of nominal diameter. The reaming tool further comprises at least two peripherally arranged guide elements, which lie on a guide circle arranged eccentrically to the center axis or having a larger diameter than the cutting circle. As a result of this measure, high surface quality is obtained, in particular even in soft materials, since the reaming tool is clamped in the direction of the reaming cutter.
