An indexable milling cutting insert comprising:
- an opposed outside and inside;
- a periphery;
- a plurality of homologous and alternately individually usable cutting edges;
- and
- a centre axis, which extends between the outside and inside, wherein the cutting edges are rotationally symmetrically arranged with respect to the centre axis, and wherein the outside side includes a hub portion, which is centred around the centre axis, the outside including a plurality of ridges, which extend from the hub portion toward the periphery;
- a plurality of chip channels countersunk in the outside, wherein the chip channels are tangentially spaced-apart via the ridges, which individually include one of said cutting edges, each one of said cutting edges being formed between, a chip surface, which is situated in a flank of an appurtenant ridge and which is included in a first chip channel, and a clearance surface, which is situated on a crown of the appurtenant ridge and which adjoins a second chip channel.
