Abstract:
(EN) This rotary cutting tool has a body part and a shank part. The body part has a tip. The shank part is continuous to the body part on the opposite side of the tip. The body part is provided with: a first cutting blade having a positive twist angle; and a second cutting blade that has a negative twist angle and that is separated from the first cutting blade. Each of the first cutting blade and the second cutting blade is continuously provided from the tip to the shank part.
(FR) 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。
