Abstract
UN TREPAN CAROTTIER DIAMANTE COMPREND UN CORPS ANNULAIRE A L'EXTREMITE DUQUEL EST FIXEE UNE COURONNE PRESENTANT UNE FACE DE COUPE. CETTE COURONNE 6 EST COMPOSEE DE SEGMENTS COMPOSITES RADIAUX 18 SEPARES PAR DE LA MATIERE D'ENTRETOISEMENT 24, LE TOUT ABOUTISSANT A LA FACE DE COUPE 10 POUR S'USER AVEC ELLE. CHAQUE SEGMENT COMPOSITE 18 EST CONSTITUE D'UNE SUCCESSION RADIALE DE SEGMENTS IMPREGNES DE DIAMANTS 20 ALTERNANT AVEC DE LA MATIERE D'ESPACEMENT 22. CES DERNIERS SEGMENTS 20 ONT UNE PLUS GRANDE RESISTANCE A L'ABRASION QUE LA MATIERE D'ESPACEMENT 22 ENTRE EUX, LAQUELLE A ELLE-MEME UNE PLUS GRANDE RESISTANCE A L'ABRASION QUE LA MATIERE D'ENTRETOISEMENT 24. APPLICATION AU MATERIEL DE FORAGE.
