Abstract: A cutting insert for use in high-feed milling has a 180° rotational symmetry about a center axis and includes first and second major faces, a median plane extending between said major faces perpendicularly to the centre axis, a first main cutting edge and an associated first ramping cutting edge, and a second main cutting edge and an associated second ramping cutting edge. Each main cutting edge has a first end facing the associated ramping cutting edge and an opposite second end. Each ramping cutting edge has a first end facing the associated main cutting edge and an opposite second end. The cutting edges slope such that their second ends are located closer to the median plane than the respective first ends, and the second ends of the main cutting edges, are located closer to the median plane than the second ends of the ramping cutting edges.

Abstract: A milling tool body is rotatable around a central rotation axis and includes a front end surface and a rear end surface. An envelope surface surrounds the axis and extends between the rear end surface and the front end surface. A plurality of insert pockets are formed in a transition between the envelope surface and the front end surface. A first central through-hole of constant diameter extends between the rear end surface and the front surface. The locking disc has a second central through-hole and a fastening device is arranged to extend through the second central through-hole. The locking disc is arranged to press against the front end surface of the milling tool body when mounting the milling tool body to an adaptor by the fastening device. The fastening device is mountable to an end of the adaptor insertable into the first central through-hole.
