    • A double-sided cutting insert has top and bottom surfaces and two major side surfaces connected by two minor side surfaces. Each major side surface has two distinct relief surfaces which are inclined in opposite directions and merge at a transition surface extending between top and bottom surfaces. A first major cutting edge is defined between the first relief surface and the top surface and a second major cutting edge is defined between the second relief surface and the bottom surface. Each major cutting edge is tangent to an associated transition cutting edge defined between the transition surface and the insert top or insert bottom surface. An insert holder for the insert has three support sections accordant with three abutment sections of the insert.
    • 双面切削刀片具有顶表面和底表面以及由两个较小侧表面连接的两个主侧面。 每个主侧面具有两个不同的浮雕表面,它们在相反方向上倾斜并且在顶表面和底表面之间延伸的过渡表面处合并。 第一主切削刃被限定在第一浮雕表面和顶表面之间,并且第二主切削刃被限定在第二浮雕表面和底表面之间。 每个主切削刃与过渡表面和刀片顶部或刀片底面之间限定的相关过渡切削刃相切。 用于插入件的插入物保持器具有与插入件的三个邻接部分相一致的三个支撑部分。
