Abstract: A cutting insert having a plurality of corner cutting edges has an upper face, a lower face, two longitudinal side faces and two transversal side faces connecting the upper face and the lower face. A through hole passes through central parts of the upper face and the lower face. The longitudinal side faces are opposite to each other and normal to both upper and lower faces, as are the transversal side faces. The upper face and the lower face are each provided with two chip discharge grooves, each chip discharge groove extending along a corresponding one of the transversal side faces, the two chip discharge grooves being inclined oppositely in the transverse direction so that the upper face and the lower face are each provided with two corner cutting edges at diagonally opposite corners. The longitudinal length of the insert is longer than the transversal length of the insert. The cutting insert can be mounted stably to a small-diametered cutter with a sufficient mounting surface.

Abstract translation: 具有多个角切削刃的切削刀片具有连接上表面和下表面的上表面，下表面，两个纵向侧面和两个横向侧面。 通孔穿过上表面和下表面的中心部分。 纵向侧面彼此相对并且垂直于上表面和下表面，横向侧面也是如此。 上表面和下表面均设置有两个排屑槽，每个排屑槽沿着相应的一个横向侧面延伸，两个排屑槽在横向相反地倾斜，使得上表面和 下表面在对角线相对的角落处设有两个角切削刃。 插入件的纵向长度大于插入件的横向长度。 切削刀片可以稳定地安装到具有足够安装表面的小直径刀具上。
