Abstract

The invention concerns a milling tool which is fitted to the toolholder of a machine tool by means of an attachment screw. The mandrel on which the tool is mounted has a bore passing through it, the bore ending at the bore for the tool attachment screw. Locateed in the head of the screw are radial channels which are connected to the bore and which allow cooling liquid to emerge towards the cutting edges of the tool.
