Abstract

L'invention concerne un burin à tige circulaire (30) comprenant une tige (31) qui est maintenue dans l'orifice (41) d'un porte-burin (40) au moyen d'une douille de serrage (10). Selon l'invention, la tige (31) est maintenue dans la douille de serrage (10) de manière rotative. Cette douille de serrage (10) comprend un ou plusieurs éléments de retenue (16, 17, 18) faisant saillie vers l'intérieur et s'engageant dans une rainure périphérique (39) ménagée dans la tige (31) du burin à tige circulaire (30), de manière que la douille de serrage (10) soit fixée de manière à ne pas pouvoir être déplacée dans la direction axiale sur la tige (31) du burin à tige circulaire. La douille de serrage (10) est configurée de manière symétrique par rapport au plan transversal médian (38), et peut par conséquent être fixée sur la tige (31) selon un angle de 180°.
