ABSTRACT:
A tool for chip-removing machining includes a holder on which in indexible cutting insert is mounted. The holder includes a first base surface on which a plurality of male parts are disposed to define an insert seat. The insert includes generally parallel second and third base surfaces, each having a plurality of female parts disposed therein. The insert is invertible such that the female parts of one of the second and third base surfaces receive respective male parts of the holder. A fastener secures the insert on the seat, with the male parts tightly fitted in the female parts. The male parts are flexible relative to the first base surface to ensure a firm abutment of the male parts with surfaces of respective female parts.
