The invention discloses a milling cutter for an ultrahigh-voltage conductor, relating to the improvement on a special milling cutter structure for machining a conductor in an ultrahigh-voltage power grid. By improving the milling cutter structure, the phenomena of cutter obstruction and cutter clamping are avoided. The milling cutter is of a disc shape, two end surfaces of the disc-shaped milling cutter are conical surfaces, and a cutter tooth part is thicker than a cutter hole part. According to the invention, the structure of a common milling cutter of which the two end surfaces are planes is changed, and the two end surfaces of the milling cutter are changed into the conical surfaces specific to the characteristic that an aluminum material has a high thermal deformation coefficient.
