    • A double-sided reversible and indexable cutting insert comprises identical opposing first and second end faces (28) and a peripheral side surface (32) extending therebetween and a clamping through-bore (38) extending between, and opening out to, the first and second end faces, the cutting insert having a median plane extending between the first and second end faces, a through-bore axis extending perpendicularly through the median plane, and an Y-fold rotational symmetry about the through-bore axis; the peripheral side surface comprising Y major side surfaces (34) and Y minor side surfaces, each minor side surfaces interconnecting two adjacent major side surfaces (34); each minor side surface is a section of a single cylindrical surface having a given radius (R), the given radius (R) is greater than a minor side surface distance (D) of each minor side surface from the through-bore axis. ® KIPO & WIPO 2008
    • 双面可逆和可转位的切削刀片包括相同的相对的第一和第二端面(28)和在其间延伸的周边侧表面(32),以及夹紧通孔(38),其在第一和第二端面 所述切削刀片具有在所述第一和第二端面之间延伸的中间平面,垂直于所述中间平面延伸的通孔轴线和围绕所述通孔轴线的Y形折叠对称; 所述周边侧表面包括Y个主要侧表面(34)和Y个较小侧表面,每个较小侧表面互连两个相邻的主侧表面(34); 每个次侧面是具有给定半径(R)的单个圆柱形表面的一部分,给定半径(R)大于每个次侧表面与通孔轴线的次侧表面距离(D)。 ®KIPO&WIPO 2008
