A circular arch milling cutter comprises a shaft (1) and a light metal cutting part (2) strongly connected with the shaft (1). The cutting part comprises cutting sawteeth (8a,8b,8c), wherein multiple cutting sawteeth (8a,8b,8c) form a sawtooth part group. Only a first cutting sawtooth (8a) of each sawteeth group is extended toward a rotating shaft (3). The other cutting sawteeth (8b,8c) of each sawtooth group are ended on the surface (17a) having no sawtooth part group, and two adjacent first cutting sawteeth (8a) are limited between the surfaces. |
