Abstract

L'invention concerne un trépan qui peut comprendre un corps. Un trépan peut comprendre une pluralité de lames s'étendant à partir du corps. Un trépan peut comprendre un raccord de trépan s'étendant vers le haut du trou à partir du corps. Un trépan peut comprendre une jupe s'étendant à partir du corps, la jupe s'étendant au moins partiellement sur le raccord de trépan pour former un espace de liaison annulaire entre la jupe et le raccord de trépan.
