  • Patent number: 11135656
    Abstract: A cutting tool includes a holder having an upper jaw and a lower jaw, and an insert clamped between the jaws. A large-diameter hole in a lower-jaw side of the holder communicates with a lower-jaw channel, and a threaded hole in an upper-jaw side of the holder communicates with an upper-jaw channel. A threaded member has a head, a closed-bottom hollow open to the head, branch holes through which the hollow communicates with an outer circumferential surface thereof, and a screw-driving portion in a front end thereof. The threaded member is inserted from the large-diameter hole and screwed into the threaded hole until a front surface of the head seats on a bearing surface of the large-diameter hole and clamps the insert. Then, the large diameter hole, the lower-jaw channel, the hollow, the branch holes, and the upper-jaw channel are in communication for supplying coolant to the insert.

    Abstract: A rotary cutting tool with a longitudinal axis includes a shank portion and a cutting portion defining a length of cut. The cutting portion includes a plurality of blades separated by flutes extending along the length of cut. A first blade forms a first helix angle with respect to the longitudinal axis at the cutting tip. A second blade adjacent the first blade forms a second, different helix angle with respect to the longitudinal axis at the cutting tip. The cutting edge of the first blade is formed at a first distance with respect to the cutting edge of the second blade. A helix angle of at least one of the plurality of blades varies along the length of cut and a distance between cutting edges of the first and second blades varies along the length of cut.
