Abstract

L'invention porte sur un outil de coupe. Vu d'en face d'une surface de base (6) d'un logement de fixation de plaquette, l'angle (α) formé entre des première et seconde surfaces de paroi de retenue (7a, 7b) qui s'élèvent sur la surface de base (6), est plus petit que l'angle (β) formé entre deux surfaces périphériques d'une plaquette de coupe. Lesdites surfaces périphériques précitées butent respectivement contre les première et seconde surfaces de parois de retenue. L'une des surfaces périphériques de la plaquette de coupe bute contre la première surface de paroi de retenue (7a) qui est orientée de sorte qu'elle est à peu près parallèle à la ligne sur laquelle se trouve la première surface de paroi de retenue (7a) et l'autre surface périphérique bute contre une extrémité de la seconde surface de paroi de retenue (7b).
