Abstract

Outil de forage rotatif comprenant une face de coupe comportant un bord périphérique et un évidement central, une série d'ajutages d'évacuation de fluide étant montés dans la face de coupe, une série d'éléments coupeurs étant montés dans le bord périphérique ainsi que dans l'évidement pour briser un noyau de terre formé au fur et à mésure que l'outil coupe à traves la formation, une série de passages d'évacuation latéraux s'étendant radialement dans ledit corps à partir de l'évidement précité et s'étendant le long du bord périphérique pour former des interruptions circonférentielles dans celui-ci, une saillie convexe disposée centralement étant agencée pour entrer en contact avec le noyau de terre et briser celui-ci ainsi que pour faire dévier les déblais de forage vers les passages d'évacuation latéraux précités.
