Abstract
La présente invention concerne une lame de scie comportant au moins une pièce de support (12a ; 12b ; 12c ; 12d ; 12e) qui présente au moins un côté de coupe (22a ; 22b ; 22c ; 22d ; 22e), et ayant une pluralité d'inserts (14a ; 14b ; 14c ; 14d ; 14e) agencés de manière à être disposés à distance les uns des autres, les inserts (14a ; 14b ; 14c ; 14d ; 14e) étant fabriqués dans un matériau, en particulier un carbure, qui est plus dur qu'un matériau de la pièce de support (12a ; 12b ; 12c ; 12d ; 12e), les inserts (14a ; 14b ; 14c ; 14d ; 14e) étant chacun fixés à l'au moins un côté de coupe (22a ; 22b ; 22c ; 22d ; 22e) de la pièce de support (12a ; 12b ; 12c ; 12d ; 12e). Selon la présente invention, les inserts (14a ; 14b ; 14c ; 14d ; 14e) forment chacun au moins partiellement au moins deux dents de scie (16a ; 16b ; 16c ; 16d ; 16e).
