Abstract

L'invention concerne une tête d'outil (11, 11a, 11b) pour une machine à travailler le bois, présentant un corps de base cylindrique, conique ou profilé, qui présente au moins deux logements d'outil (13) disposés de manière régulièrement répartie sur sa périphérie pour loger une plaquette de coupe (15). Les logements d'outil (13) comprennent des rainures (19) qui se rétrécissent à chaque fois dans la direction radiale, dans lesquelles est serrée à chaque fois une plaquette de coupe (15) entre une première paroi latérale (27) des rainures (19) et un élément de verrouillage (25). Une première liaison par complémentarité de forme existe entre la plaquette de coupe (15) et la première paroi latérale. En outre, une cale de serrage (23) est disposée entre l'élément de verrouillage (25) et une deuxième paroi latérale (31) opposée à la première paroi latérale (27) de la rainure. Selon l'invention, une deuxième liaison par complémentarité de forme existe entre l'élément de verrouillage (25) et la cale de serrage (23). De ce fait, une mise en place radiale d'une plaquette de coupe (15) est rendue possible.
