  • Patent number: 5222842
    Abstract: The milling tool, in one form, has a shank having a shank rotation axis, a first cutting-edge carrier having at least one cutting edge and at least two arched areas and a second cutting-edge carrier having at least one cutting edge and at least two arched areas. The arched areas are shaped and positioned to form a tubular socket in which the shank is attached with both cutting-edge carriers radially projecting in a lobe-like manner from the shank and being rotatable about the shank rotation axis. The at least two arched areas of both cutting-edge carriers are spaced from each other axially, have surfaces normal to the shank rotation axis, arch in the same direction and are displaced from and parallel to the shank rotation axis so that the first and second cutting-edge carriers mutually overlap to form the tubular socket for the shank so that, when the shank is attached in the tubular socket, the cutting-edge carriers are locked against each other.
