The invention concerns an indexable cutting insert (2) intended for chip removing machining and of the type that comprises a plurality of cutting tips (21) that protrude from a central core (20) and individually include a cutting edge (25), which is formed in a transition between an upper side serving as chip surface (26), and a clearance surface (33), which extends between the upper side and an under side. According to the invention, the cutting insert comprises six equally long cutting tips (21 a, 21 b, 21 c, 21 d, 21 e and 21 f) that are located in pairs along the co-ordinate axes (X, Y, Z) of a three-dimensional, orthogonal system of co-ordinates, the origin of which is situated in the core (20). By arranging the cutting tips (21 a, 21 b, 21 c, 21 d, 21 e and 21 f) in this way, the inactive cutting tips, which are situated behind an active cutting tip, can be contained within a limited volume and therefore be installed in tool basic bodies having tapering parts. In addition, the invention relates to a tool equipped with the cutting insert according to the invention as well as a tool basic body as such. |
