Abstract
A rotatable cutting tool, e.g., a milling cutter, includes a rotatable base body and a cutting insert, which in addition to two opposite side surfaces has front and rear end surfaces. For axial fine-adjustment of the cutting insert, a set screw is arranged that is located in an area behind the cutting insert and inclined at an obtuse angle to a side surface of the cutting insert. During an unscrewing of the set screw, it presses against the rear end surface of the cutting insert with the purpose of moving the cutting insert in the direction axially forwards, whereby the screw, due to the obtuse angle, is centrifugally secured by means of the actual cutting insert.
