Abstract

Cette invention concerne un trépan comprenant des éléments de coupe. La coupe transversale desdits éléments de coupe est de forme ovale. Dans un premier mode de réalisation, l'axe majeur est perpendiculaire à la surface de la lame du trépan. L'invention concerne aussi un procédé comprenant l'étape consistant à utiliser un outil de fraisage ayant une coupe transversale ovale formant ainsi des poches dans les lames du trépan pour recevoir les éléments de coupe de forme ovale. L'utilisation de l'outil de forme ovale entraîne aussi la formation d'un demi-ovoïde à l'extrémité fermée de la poche.
