Abstract: A tool for cutting metal machining comprises one or several cutting insert seats (1), each one for an indexable cutting insert, each insert seat comprising a bottom support surface (10) and at least two side surfaces, which form a right angle with each other. One of these side surfaces comprises two side surfaces (12, 16), which are located at different distances from the bottom support surface (10), one of these being intended as a support surface for square cutting inserts and the other as a support surface for specially shaped hexagonal inserts. In this way, one and the same insert seat can accommodate either a square or a hexagonal cutting insert, which considerably improves cutting economy.

Abstract: A cutting insert for chip-breaking metal machining comprises an upper chip surface, a lower bottom surface, which is substantially plane parallel with the chip surface, one or several side surfaces that extend between said chip and bottom surfaces, and a through hole (12) for the accommodation of a locking screw (11). Said hole (12) comprises a rotation-asymmetrical portion (16) comprising a plurality of radially bulging portions (17) extending in the direction of the hole, the transitions (18) extending substantially in the direction of the hole between adjacent bulging portions being intended to pairwise abutting against the locking screw (11) and guiding the insert towards the right positioning in an insert seat, before the insert is clamped. In this way, it becomes considerably easier to position the cutting insert, particularly when it has a larger number of cutting edges, e.g. six or eight.
