ABSTRACT:
A tool for chip removing machining includes a holder and at least one cutting insert received in the holder. The holder is provided with at least one insert pocket, in which the cutting insert is intended to be received, and an opening connected to the insert pocket. The insert pocket has a first holding member provided along the periphery of the insert pocket, and the cutting insert has an anchor section and an edge portion connected to the anchor section. A second holding member is provided along the circumference of the anchor section. The first and the second holding members are intended to cooperate when the cutting insert is mounted in the insert pocket. The periphery of the insert pocket, at least partly, is defined by one or more circular arcs with a common center of rotation. The anchor section is provided with a number of holding members distributed along its circumference, and portions of these holding members located furthest away from of the cutting insert center are defined by circular arcs having a common center of rotation. The circular arcs are located at the same distance from the common center of rotation.
