The invention relates to a cutting insert for machining down workpieces. Said insert comprises several cutting edges (10), in particular for roughing work. A curved cutting corner, or a corner consisting of a large number of short, respectively linear edge sections positioned at obtuse angles in relation to one another, is positioned between neighbouring cutting edges (10). According to the invention, the cutting surface comprises a bevel (14, 15), which extends along the cutting edge (10). The section of bevel lying in the centre of the cutting edge (10) is broader than the two adjacent bevelled areas on either side, the broader bevel being between 1.5 and 4 times as broad as the breadth of the laterally adjacent bevel.
