A tool holder simultaneously carries at least two diametrically arranged tool heads, each tool head carrying cutting inserts for chip removing machining. The tool holder includes an adaptor connected to a coupling. The adaptor has at least two diametrically opposite side surfaces which-diverge away from the coupling. The side surfaces have seats in order to replaceably receive respective tool heads. A line which lies in both a first basal plane and in one of the side surfaces forms an angle in the interval 1°-15° with a longitudinal center line of the tool holder.
