A milling cutter includes a rotary body and a plurality of recesses spaced around its outer periphery for receiving insert-carrying cartridges. Each cartridge is wedge-shaped and is retained in place by a clamping wedge which is fastened in the respective recess by a clamp screw. Each cartridge has serrations on its rear surface which engage corresponding serrations on the rearward wall of the recess. A locating pin extends between a wall of the recess and a surface of the cartridge. The cartridge carries a spring which is compressed by the clamping wedge such that the spring biases the cartridge against the rearward wall of the recess.
