Abstract

L'outil de forage comprend un corps d'outil comportant une face d'extrémité active et plusieurs organes de coupe montés dans le corps d'outil et s'étendant à travers la face d'extrémité active, les organes de coupe comportant des faces de coupe propres à attaquer une formation géologique à l'entailler selon un profil tridimensionnel souhaité, les faces de coupe délimitant des surfaces présentant des angles de pente effective de coupe qui deviennent de plus en plus négatifs à mesure que l'on s'écarte du profil.
