Abstract

La présente invention concerne un trépan de forage qui a des cônes rotatifs sur lesquels sont installés des rangés d'éléments en carbure. Un nez est disposé symétriquement sur un axe de cône de l'un des cônes. Le nez a un cœur central qui fait saillie vers l'extérieur. Une base joint le métal de support du cône. Une extrémité libre est opposée à la base. Des dents sont formées sur le cône entre la base et l'extrémité libre, les dents s'étendant radialement vers l'extérieur. Une couche de renforcement se trouve sur les dents. Des renforcements intermédiaires s'étendent vers l'extérieur à partir du cœur entre chacune des dents. Les renforcements intermédiaires peuvent être des languettes et s'étendent de préférence sur la même distance depuis que le cœur que les dents.
