Abstract
L'invention concerne un aléseur (100) comportant au moins un corps de tourillon (110) et au moins un corps de coupe toroïdal (116). Ledit corps de coupe toroïdal (116) présente un diamètre maximal (MD), un périmètre extérieur (OP) et une pluralité d'éléments de coupe (112, 145, 149) sur la surface de coupe (118). Le corps de coupe toroïdal est monté rotatif sur le tourillon (110). Lorsqu'il est en position de montage, l'axe de rotation (RA) du corps de coupe toroïdal (116) (au moins au nombre de un) coupe l'axe longitudinal du train de tiges de forage, en un angle aigu.
