A disc-shaped mill cutting tool, with a disc-shaped main body which has a central axial through bore for the accommodation of a drive shaft as well as a plurality of pockets for the accommodation of cutting inserts on its perimeter, wherein chip spaces are associated to the pockets and a channel system is arranged between the central through bore and the chip spaces for the passage of cooling fluid which emerges in the chip spaces, characterised in that the disc-shaped main body is formed by at least two sub-discs coaxially sitting close together, which form a concentrically arranged ring channel between themselves, which is connected to the through bore via at least one connection channel, and the ring channel is connected to the chip spaces via relatively short bore portions.
