Abstract

La présente invention concerne un trépan tranchant (20) utile pour impacter des strates terrestres. Le trépan tranchant comprend un corps (22) de foret tranchant allongé extrêmement résistant à l’usure, qui possède une extrémité avant axiale (24) et une extrémité arrière axiale (26) ; une section formant tête (30) de dimension élargie du côté de l’extrémité avant axiale (24) ; et une section formant tige (32) de dimension réduite du côté de l’extrémité arrière axiale (26). Le corps (22) de foret tranchant allongé extrêmement résistant à l’usure, a une dimension transversale maximale (E) et une longueur axiale longitudinale (B). Le trépan tranchant comprend un insert (40) extra-dur qui est fixé à la section formant tête (30) du côté de l'extrémité avant axiale (24) du corps (22) du trépan tranchant. Le trépan tranchant (40) a un rapport de minceur qui correspond au rapport de la dimension transversale maximale (E) à la longueur axiale longitudinale (B), le trépan tranchant (40) présentant un rapport de minceur compris entre 0,15 environ et 0,60 environ.
