Abstract

L'invention porte sur un outil rotatif pour le forage d'un matériau souterrain. L'outil rotatif comprend un corps d'outil comportant une extrémité de couronne distale comprenant une série périphérique de lames de coupe élevées avec des fentes pour les débris dans les cavités entre celles-ci. Des éléments de coupe sont disposés à proximité du bord périphérique antérieur des lames de coupe élevées et des structures de régulation de coupe sont disposées à l'intérieur dans les éléments de coupe sur une surface antérieure d'une fente adjacente pour les débris. Les structures de régulation de coupe sont fixées de manière libérable au corps d'outil dans la fente adjacente pour les débris, grâce à quoi on remet à neuf un outil rotatif utilisé par retrait des structures de régulation de coupe usées sans dégradation du corps d'outil et remplacement des structures de régulation de coupe usées par installation d'une nouvelle structure de régulation de coupe dans les emplacements des structures de régulation de coupe usées.
