Abstract

L'invention concerne un trépan rotatif. Ce trépan est constitué d'un corps de base dont la périphérie extérieure est garnie d'éléments de coupe qui sont formés chacun d'une partie de support en métal dur ou en matière analogue et d'une partie de coupe en diamant polycristallin ou en matière analogue montée sur cette patie de support, les éléments de coupe étant formés chacun d'une section d'un corps fritté dont la partie de support entoure la partie de coupe au moins à sa périphérie sous la forme d'une enveloppe. Ce trépan rotatif est destiné aux forages profonds.
