    摘要: A rotary tool (T) has a rotary segment (10) with an opposed surface opposed to a work surface and a plurality of cutting parts (20) arranged on the opposed surface. Some cutting parts (20) include tips (22a) made of a grinding tool segment obtained by binding abrasive grains by a metal binder and the other cutting parts (20) include tips (24a) made of a sintered material harder than the grinding tool segment, and the respective cutting parts (20) are arranged such that the tips (24a) are located at positions more outward than the tips (22a) with respect to radial directions of the rotary segment.
