Abstract

L'invention concerne un ensemble formant trépan comprenant un trépan ayant une première extrémité, une deuxième extrémité opposée à la première extrémité, un axe de rotation s'étendant de manière centrale au travers du trépan entre les première et deuxième extrémités, une tige disposée au niveau de la première extrémité, et une goujure. L'ensemble formant trépan comprend également une tête de coupe couplée à la deuxième extrémité du trépan. La tête de coupe comprend un bord de coupe, une première surface de bord externe adjacente par rapport au bord de coupe, une deuxième surface de bord externe opposée à la première surface de bord externe, et une section de largeur réduite unique formée dans la tête de coupe. La section à largeur réduite unique est positionnée de manière adjacente par rapport au premier bord externe.
