FIELD: milling. SUBSTANCE: group of inventions relates to versions of mills used for machining parts on milling machines. It consists of a housing in the form of a rotation body, on the surface of which there are teeth with a non-uniform end pitch. Dependences defining the value of said pitch depending on the number of cutter teeth are given, as a result of which the cutter has no repeated tooth pitches. EFFECT: minimized probability of resonant phenomena during operation of cutter, reduced waviness and roughness of machined surface.
