摘要： A reamer incudes a core and a plurality of outer-circumference cutting edges provided on an outer circumference of the core and made of a hard tool material. The core extends from a front end to a rear end. The core is provided with a plurality of flutes from the front end to the rear end. A center-of-gravity adjustment portion, which adjusts a distance from a center of rotation to a center of gravity, is provided at least partially from terminal ends of the plurality of flutes on a rear end side to the rear end of the core. The center-of-gravity adjustment portion causes the deviation of the center of gravity from the center of rotation to be smaller than when no center-of-gravity adjustment portion is provided.
