    • A four-sided cutting insert (1) has a top surface (3), a bottom surface (5) and a pair of first side surfaces (11) connected to a pair of second side surfaces (13) via corner surfaces. Opposite corners of the cutting insert are provided with a first pair of corner edges (19) defined between a first edge (15) and an associated second edge (17). Proximate its leading end, the first edge has a main portion which, in a top view of the insert, extends inwardly toward the first axis (alpha) at a first angle. In a side view, the first edge slopes downwardly from the corner edge in the direction of the base surface. The associated second edge, in the top view of the insert, extends from the corner edge in an outward direction relative to the second axis (β).
    • 四面切削刀片(1)具有通过拐角表面连接到一对第二侧表面(13)的顶表面(3),底表面(5)和一对第一侧表面(11)。 切削刀片的相对的角部设置有限定在第一边缘(15)和相关联的第二边缘(17)之间的第一对角边缘(19)。 近似其前端,第一边缘具有主要部分,其在插入件的俯视图中以第一角度朝向第一轴线(α)向内延伸。 在侧视图中,第一边缘在基部表面的方向上从拐角边缘向下倾斜。 在插入件的顶视图中,相关联的第二边缘相对于第二轴线(β)从角部边缘向外延伸。
