Abstract
A milling tool is disclosed having a front head and a rear holder, which are detachably connected by means of a male/female coupling as well as a screw and a washer. Via a main duct, cooling liquid is fed to a chamber, from which it is fed out via branch ducts to individual milling inserts. The front chamber is closed by means of a cover that is held applied against a ring surface surrounding the chamber. The cover is tightenable by means of a threaded joint that is operative independently of a threaded joint between the screw and a front section of the main duct.
