Summary:To provide a rotation tool which is advantageous for cutting of a square corner part.SOLUTION: A rotary tool 101 is rotated around an axis to be used and has: a shank 105; and a cutting part 109 located at the tip side of the shank 105. The cutting part 109 has an outer peripheral surface 111 exposed to the outside of the tool 101 over an entire periphery of the tool 101 around its axis. The outer peripheral surface 111 has a first cutting edge 117A having a length in an axial direction of the tool 101. When viewed in a direction parallel to an axis CL1 of the shank 105, a distance between the first cutting blade 117A and the axis CL1 is shorter than a maximum distance between the outer peripheral surface 111 and the axis CL1.SELECTED DRAWING: Figure 3 【課題】角隅部の切削に有利な回転工具を提供する。【解決手段】軸回りに回転されて使用される回転工具１０１は、シャンク１０５と、シャンク１０５の先端側に位置している刃部１０９と、を有している。刃部１０９は、工具１０１の軸回りの１周に亘って工具１０１の外部に露出している外周面１１１を有している。外周面１１１は、工具１０１の軸方向に長さを有する第１切れ刃１１７Ａを有している。シャンク１０５の軸心ＣＬ１に平行に見て、第１切れ刃１１７Ａと軸心ＣＬ１との距離が、外周面１１１と軸心ＣＬ１との最大距離よりも短い。【選択図】図３
