Abstract

L'invention concerne un élément de coupe qui comprend un corps ayant deux plans, chacun des deux plans définissant une pluralité de bords, et un support s'étendant à partir d'un premier des deux plans. Le support et le corps sont configurés de telle sorte que lorsque l'élément de coupe est en appui contre une surface plane de telle sorte qu'au moins l'un de la pluralité de bords et le support sont en contact avec la surface plane, le second des deux plans forme un angle aigu avec la surface plane. En outre, une saillie s'étend latéralement à partir d'au moins une face du corps et un renfoncement est formé dans au moins une face du corps. La saillie et le renfoncement sont complémentaires l'un de l'autre de telle sorte que la saillie d'un premier des éléments de coupe peut être positionnée à l'intérieur du renfoncement d'un second des éléments de coupe.
