Summary:To provide a rotary cutting tool which can make cutting chips finer without changing a cutting edge shape and maintain cutting performance and machining accuracy.SOLUTION: In a rotary cutting tool 1, a tip 3 is fixed to a tip of a shaft-shaped shank 2. The tip 3 has a cutting blade 31 and a rake face 32 extending from the cutting blade 31. A roughened rough surface region 34 is formed in the vicinity of the cutting blade 31 on the rake face 32. In the rotary cutting tool 1, cutting chips are made finer by formation of the rough surface region 34 in the vicinity of the cutting blade 31 on the rake face 32. Thus, cutting chips can be made finer without changing the cutting blade shape.SELECTED DRAWING: Figure 2 【課題】刃先形状を変えることなく切粉を微細化することができ、かつ切削性能や加工精度を維持することができる回転切削工具を提供する。【解決手段】回転切削工具１は、軸状のシャンク２の先端にチップ３が固着された回転切削工具１である。チップ３は、切刃３１と、切刃３１から延びるすくい面３２と、を有し、すくい面３２における切刃３１の近傍に、粗面化された粗面領域３４が形成されている。この回転切削工具１では、すくい面３２における切刃３１の近傍に粗面領域３４が形成されていることで、切粉が微細化される。これにより、刃先形状を変えることなく切粉を微細化することができる。【選択図】図２
