るなど工業上有用な特性をもつものである。From the results shown in Tables 2 to 6, in the coated carbide end mills 1 to 43 of the present invention, despite the high feed and high depth of cut cutting accompanied by high heat generation, the hard vapor deposition layer was exfoliated. While it does not occur and shows excellent wear resistance,
It is apparent that in the conventional coated carbide end mills 1 to 12, peeling occurs in the hard vapor deposition layer and the service life is reached in a relatively short time. As described above, the coated carbide end mill of the present invention peels off to a hard vapor deposition layer not only in ordinary cutting but also when used for cutting with high heat generation such as high-cutting cutting and high-feed cutting. Since it exhibits excellent cutting performance over a long period of time with no occurrence of cutting edge, it has industrially useful characteristics such as high performance of cutting machines and labor saving of cutting processing. .
