PROBLEM TO BE SOLVED: To provide a coupling mechanism for a cutting tool.SOLUTION: A rotary cutting tool includes a cutter of generally cylindrical shape disposed about a central longitudinal axis. The cutter has a first end having an active fluted portion and an opposite second end, the second end having a male threaded portion disposed thereabout. The cutting tool further includes a shank of generally cylindrical shape disposed about the central longitudinal axis, the shank having a recessed female threaded portion formed in a first end. The male threaded portion includes a number of threads disposed at a first pitch and the female threaded portion includes a number of threads disposed at a second pitch different than the first pitch. The cutter and the shank are selectively coupled via threaded engagement of the male threaded portion and the female threaded portion. 【課題】切削工具用の連結機構を提供する。【解決手段】回転切削工具は、長手方向中心軸線を中心として配置された略円筒形状のカッターを含む。カッターは、作動溝付部を有する第１の端部と、反対側の第２の端部であって、これを中心として雄ねじ部が配置された第２の端部とを有する。切削工具は更に、長手方向中心軸線を中心として配置された略円筒形状のシャンクであって、凹状の雌ねじ部が第１の端部に形成されたシャンクを含む。雄ねじ部は、第１のピッチで配置された複数のねじ山を含み、雌ねじ部は、第１のピッチとは異なる第２のピッチで配置された複数のねじ山を含む。カッターおよびシャンクは、雄ねじ部と雌ねじ部とのねじ係合を介して選択的に連結される。【選択図】図１Ｂ
