Abstract

L'invention concerne un foret qui comporte un bossage s'étendant de manière rotative à l'avant d'une ou plusieurs de ses lames, dans une région de calibrage du corps d'un foret pour augmenter la stabilité et réduire le choc à l'impact provoqué par la force de déséquilibre latéral agissant sur le foret lors du forage d'une formation souterraine. Le bossage comporte une surface d'appui ronde qui précède de manière rotative la surface d'appui ronde de la ou des lames. L'invention décrit également un foret qui comporte un bossage muni dans lequel s'étend un orifice de buse.
