Abstract

Les effets nuisibles des retombées sont réduits pour un trépan comprenant des molettes (29), l’une au moins des rangées les plus externes (51) des dents actives (35) contenant une ou plusieurs dents (35) dont la hauteur (65) est inférieure à la hauteur (67) d’au moins l’une des rangées les plus externes d’une autre molette sur le trépan. Le sommet (63) de cette dent (35) peut présenter une longueur (58) dans une direction circonférentielle supérieure à une largeur totale (69) de la dent (35) dans la direction allant de l'extérieur vers l'intérieur. L’invention peut être utilisée sur n’importe quelle rangée du dispositif de coupe, et pas seulement sur la rangée la plus externe (51). Cette conception peut être utilisée sur une molette ou une rangée différente, ou sur plus d’une rangée du dispositif de coupe. La caractéristique anti-retombée peut être située entre les bords d’attaque et de fuite (201) de la dent (201) sur une ou plusieurs molettes.
