Abstract

L'invention porte sur une structure pour fixer fermement un insert de coupe à un corps d'outil. La surface d'extrémité étant sur le côté de laquelle un outil de coupe (5) est formé constituant la première surface d'extrémité (2) et l'autre surface d'extrémité constituant la seconde surface d'extrémité (3), la surface latérale comprend au moins une partie de surface latérale saillante (9) qui fait saillie vers l'extérieur dans une direction à partir de la première surface d'extrémité (2) jusqu'à la seconde surface d'extrémité (3) et qui fait saillie vers l'extérieur de façon à se séparer du bord de coupe (5), vu à partir d'une direction dirigée vers la première surface d'extrémité (2). Par le fait d'amener la partie de surface latérale saillante (9) en contact avec une surface de paroi (23) d'un siège d'insert d'un corps d'outil (21), l'insert (1) peut être fermement fixé même si la surface d'une surface de logement du siège d'insert devient petite. L'insert de coupe est fermement fixé à un outil de coupe.
