Abstract

This invention relates to a cutting tool comprising a cutting insert holder with a cutting insert positioned in a cutting insert receiving site and provided with a hole. The cutting insert is clamped by a locking screw positioned in the cutting insert hole and threaded into the cutting insert holder. The end part of the locking screw, which end part is positioned in the cutting insert hole, is excentrical relative to the rest of the screw and has a cross section deviating from that of the cutting insert hole. When clamping the cutting insert there is only a point contact between the screw and the cutting insert hole.
