In one aspect, the invention relates to a cutting insert having a front cutting edge (15a) and a connecting surface (7b) having male- and/or female-like engagement means (19a, 20a), in order to rigidly secure the cutting insert, a geometrically predetermined reference locus (C) serving as a force-application spot for the clamping of the cutting insert. Characteristic of the invention is that simultaneously active engagement means are of only two types, viz. a first, elongate engagement means (19a), which is located between the front cutting edge (15a) and the reference locus (C), as well as a second, elongate engagement means (20a), which is oriented at an angle to the first engagement means and situated at a greater distance from the front cutting edge than the reference locus. In such a way, it is guaranteed that a tightening force always is applied to the cutting insert in a substantially triangular area, which is defined by the free ends of the engagement means. Furthermore, the invention relates to a tool for chip removing machining, as well as an attachment, e.g., a shim plate, for such tools. |
