Abstract
L'appareil selon l'invention comprend des outils de coupe disposés en alignements, formés de diamants, de carbonados ou d'agglomérés prémoulés d'abrasifs très durs, et des canaux de fluide qui partagent la face du trépan en lames en forme de coins et qui débouchent sur des buses disposées en spirale autour du trépan et destinées au nettoyage et à l'évacuation des débris. L'invention s'applique en particulier au forage au diamant en terrains tendres ou de dureté moyenne.
