A tool and a cutting insert for chip removing machining includes a tool body with an insert seat, a cutting insert mounted in the insert seat, and a fastening member. The cutting insert includes a first locking member extending in an area located outside of a central axis of the cutting insert. A second locking member configured to engage with the first locking member is provided in the insert seat. The fastening member extends through a through-hole and bears on a lower contact region of the cutting insert to press the cutting insert against a top support member provided rotationally ahead of the insert seat so that the second and first locking members lock with each other and form a radial support for the cutting insert, and on the other hand it presses an axial support region in the side surface of the cutting insert against an axial contact surface provided in the insert seat.

Tool for chip removing machining and a cutting insert

A milling insert suitable for shoulder milling includes a side surface extending between an upper and lower side and a cutting edge having a primary and a secondary cutting edge portion. The side surface includes an axial support surface opposite of the secondary cutting edge portion. The lower side includes a locking groove extending longitudinally, and a lower contact region formed to bear on a fastening member. The upper side has an upper contact region arranged to bear on a top support member of a tool in which the milling insert is mountable. A milling tool is provided with a top support member for bearing on the upper contact region of the milling insert, a locking ridge for locking with the locking groove, and an axial contact surface for supporting the axial support surface. A fastening member presses the milling insert against the top support member and the locking ridge.
