  • Patent number: 7121768
    Abstract: The invention concerns a cutting head (13) to be secured in an adapter (9) in a machine tool for chip removing machining. The cutting head (13) comprises a flange with a first side creating a coupling surface (4) adapted for being secured to the adapter (9). On the opposite of the flange, it is situated an other side creating at least one surface (1A) with an outwards extending protrusion (8), with securing means adapted for securing a cutting insert (5) with at least one cutting edge. The weight of the cutting head (13) is reduced as compared to the strength of the cutting head (13), and the natural frequency of the cutting head (13) is thereby increased when this is secured to the adapter (9).
