FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in milling hard-to-machine metals and other materials. Cutter comprises a shank and a cutting part with screw teeth separated by grooves for chip removal .Surface of the shank in the point of clamping of the cutter in the cartridge has notches in the form of acute-angled figures. Surface area of notches is made with hardness equal to surface hardness of jaws of clamping cartridge.
EFFECT: increasing friction coefficient of mill shank during machining.
