Abstract

L'invention concerne un outil d'usinage, notamment un outil rotatif de coupe, comprenant au moins un brin de coupe (12a; 12b; 12c; 12d) et au moins une unité de guidage de brin de coupe (14a; 14b; 14c; 14d). Selon l'invention, l'outil d'usinage comprend au moins une unité de guidage d'arête de coupe (16a; 16b; 16c; 16d) qui est apte à être disposée sur l'unité de guidage de brin de coupe (14a; 14b; 14c; 14d) et dont la dimension transversale (44a; 44b; 44c; 44d) maximale est identique ou supérieure à la largeur de coupe (62a; 62b; 62c; 62d) maximale du brin de coupe (12a; 12b; 12c; 12d).
