La contre-arête de coupe (51) du ou des corps de contre-outil (93) se présente sous la forme d'un contour fermé, et l'arête de coupe (38) du ou des corps d'outil (39) présente un contour de coupe qui correspond au contour fermé du corps de contre-outil (93). L'outil inférieur (9) porte au moins un groupe (411, 412, 418) d'au moins deux corps de contre-outil (93) qui peuvent être associés au(x) corps d'outil (39) au(x) corps d'outil (39) exclusivement par un déplacement perpendiculaire ou incliné par rapport à l'axe de positionnement (35, 48) de l'outil supérieur (11) et/ou de l'outil inférieur (9), ou par une combinaison de ce déplacement perpendiculaire ou incliné par rapport à l'axe de position (35, 48) et d'un mouvement rotatif autour de l'axe de position (35, 48) de l'outil supérieur (11) et/ou de l'outil inférieur (9). Dans ledit groupe (411, 412, 418), le contour du premier corps de contre-outil (93) correspond au contour de coupe du corps d'outil (39) avec un premier jeu de coupe, et le contour du deuxième ou de l'autre corps de contre-outil (93) correspond au contour de coupe du corps d'outil (39) avec un deuxième ou autre jeu de coupe.
