The present invention concerns a knife insert (1) for a wood-working machine, said knife insert being intended for mounting on a rotatable knife head, said knife insert having a first cutting edge (2) and a second cutting edge (3), the latter being arranged to cut obliquely to the grain of the wood stock, whereby said knife insert is adapted mountable to said knife head by its heel (4), which is the part of the insert situated closer to the center axis of the knife head than said first cutting edge (2). The first cutting edge (2) and the second cutting edge (3) are located relative to each other so that the second cutting edge (3), which cuts obliquely on the grain of stock, under all conditions hits the surface of the stock to be worked earlier than the first cutting edge (2).

Cette invention concerne une pièce rapportée de coupe (1) pour machine à usiner le bois, ladite pièce rapportée étant destinée à être montée sur une tête de coupe rotative et présentant un premier bord tranchant (2) et un deuxième bord tranchant (3), ce dernier étant configuré pour attaquer le grain du bois de biais; ladite pièce rapportée étant adaptée pour être fixée à la tête de coupe rotative par son talon (4), soit la partie de la pièce la plus proche de l'axe de rotation de la tête de coupe. Le premier bord tranchant (2) et le deuxième bord tranchant (3) sont disposés l'un par rapport à l'autre de telle manière que le deuxième bord tranchant (3), celui qui attaque le grain du bois de biais, entame en premier la pièce à usiner et ce, dans toutes les conditions.
