Summary:To provide a rotary cutting tool which can enhance workability and avoids damaging a neighboring object to be ground even if the object to be ground is close.SOLUTION: A rotary cutting tool 1 has: a flange-type base metal 10 which forms a perfect circle in top view and has a screw hole 111a threaded in parallel with an axis in a central part interior wall; and multiple grinding blades 15a-15f protruding on the side of an object to be ground from a flange face 11a of the base metal 10. The multiple grinding blades 15a-15f form a three-dimensional chip area 15 on the flange face 11a when the base metal 10 rotates about the axis. The outer diameter of the flange face 11a is greater than the outer diameter of the chip area 15.SELECTED DRAWING: Figure 1 【課題】研削対象物が近接している場合であっても隣り合う研削対象物を傷つけることがなく、かつ、作業性を向上させることができる回転刃具を提供する。【解決手段】回転刃具１は、中央部内壁に軸心と平行にネジ孔１１１ａが螺刻され、上面視で真円をなすフランジ型の台金１０と、台金１０のフランジ面１１ａから被研削物側に立設される複数の研削刃１５ａ～１５ｆとを有する。複数の研削刃１５ａ～１５ｆは、台金１０が軸心を中心に回転するときフランジ面１１ａに３次元のチップ領域１５を形成する。また、フランジ面１１ａの外径は、チップ領域１５の外径よりも大きい。【選択図】図１
