La présente invention concerne un outil de coupe rotatif présentant une partie corps et une partie tige. La partie corps présente une pointe. La partie tige prolonge la partie corps sur le côté opposé de la pointe. La partie corps comporte : une première lame de coupe ayant un angle de torsion positif ; et une seconde lame de coupe qui présente un angle de torsion négatif et qui est séparée de la première lame de coupe. Chacune de la première lame de coupe et de la seconde lame de coupe s'étend en continu de la pointe à la partie tige.
(JA)
回転切削工具は、本体部と、シャンク部とを有する。本体部は、先端を有する。シャンク部は、先端とは反対側において本体部に連なる。本体部には、正のねじれ角を有する第1切れ刃と、負のねじれ角を有しかつ第1切れ刃から離間している第2切れ刃とが設けられている。第1切れ刃および第2切れ刃の各々は、先端からシャンク部まで連続的に設けられている。
