The invention relates to a rotatable and reversible cutting attachment (1) cutting eight ways and comprising two opposing, essentially quadratic base surfaces (2) which can be mutually rotated about a central axis (A1) extending perpendicularly to said surfaces, and four identical lateral surfaces (3). A main cutter is formed between each base surface (2) and each lateral surface (3), extending only over part of the length of the lateral surface (3). Each lateral surface (3) comprises two diagonally opposed circular or curved corner edges (5) forming a secondary cutter (6) adjacent to each main cutter (4). Each lateral surface also comprises two chip cavities (7) which are set in the lateral surface (3) and extend from each corner edge (5) along the main cutter associated with the edge, up to a rear end of the chip cavity (7d).

L'invention concerne un outil de coupe rotatif et réversible (1) à huit tranchants. L'outil de coupe selon l'invention comprend deux surfaces de base opposées (2) pratiquement carrées, qui sont décalées l'une par rapport à l'autre par rotation autour d'un axe central (A1) perpendiculaire aux surfaces de base, ainsi que quatre surfaces latérales identiques (3). Entre chaque surface de base (2) et chaque surface latérale (3) est formé un tranchant principal (4) qui s'étend sur une partie seulement de la longueur de la surface latérale (3). Chaque surface latérale (3) présente deux arêtes de coin (5) en forme d'arc ou de cercle qui sont situées diagonalement à l'opposé l'une de l'autre et qui forment un tranchant secondaire (6) adjacent au tranchant principal respectif (4). Chaque surface latérale (3) présente en outre deux évidements à copeaux (7) qui sont encastrés dans la surface latérale (3) et qui s'étendent de l'arête de coin respective (5) jusqu'à une extrémité d'évidement à copeaux arrière (7d) le long du tranchant principal (4) associé à l'arête de coin concernée.
