PCT No. PCT/JP85/00687 Sec. 371 Date Aug. 13, 1986 Sec. 102(e) Date Aug. 13, 1986 PCT Filed Dec. 16, 1985 PCT Pub. No. WO86/04001 PCT Pub. Date Jul. 17, 1986.The present invention relates to a method for attaching a shell-type milling cutter wherein an area for fastening the shell-type milling cutter to its cutter arbor is increased to raise rigidity and attachment strength thereby making high-speed and heavy-duty cutting possible, so that the cutting efficiency thereof becomes substantially identical to that of an integral structure type milling cutter, besides exchange of the milling cutter can very simply be attained. The method for attaching a shell-type milling cutter according to the present invention is conducted by such a manner that the inside diameter portion of a shell-type milling cutter is formed into a tapered hole, and a bush is forcibly inserted in a gap defined between the tapered hole and a fitting shaft of a cutter arbor, whereby the milling cutter is fixed to the cutter arbor.
