Abstract

L'invention concerne une tête de forage pour un trépan rotatif munie d'ailes pivotables pouvant se déplacer radialement vers l'extérieur et vers l'intérieur. Les ailes pivotables ont des listeaux de rappel inclinés. Lorsque la tête de forage est tirée vers le haut la terre presse contre les listeaux de rappel inclinés pour les pivoter avec certitude vers l'intérieur. Utilisation pour forer des puits dans des formations terreuses et pierreuses.
