    • A metal cutting insert (10) having a pair of cutting portions (10a, 10b) disposed on either end of a shank portion (10c), each cutting portion having a front clearance face (20), the upper boundary of which defines a cutting edge (14). A pair of spaced apart chip breaking surfaces (26a, 26b, 28a, 28b) commence at or near the cutting edge and extend away from the cutting edge. A pair of secondary chip breaking surfaces (44a, 44b, 46a, 46b, 48a, 48b, 50a, 50b) are located downstream of the first chip breaking surfaces and are interconnected with associated first chip breaking surfaces by transition surfaces. A center channel (30) is located between the chip breaking surfaces and includes an entry portion (30a). A tool holder (100) includes a base (102) and clamping arm (104) which together define a gap (106) for receiving one of the cutting portions of the insert.
    • 一种金属切削刀片(10),其具有设置在柄部(10c)的任一端上的一对切削部分(10a,10b),每个切削部分具有前间隙面(20),其上边界限定切削 边缘(14)。 一对间隔开的断屑表面(26a,26b,28a,28b)在切削刃处或附近开始并远离切削刃延伸。 一对次级断屑表面(44a,44b,46a,46b,48a,48b,50a,50b)位于第一断屑表面的下游并且通过过渡表面与相关的第一断屑表面相互连接。 中心通道(30)位于断屑表面之间并包括入口部分(30a)。 刀架(100)包括基部(102)和夹臂(104),它们一起限定用于接纳刀片的切削部分之一的间隙(106)。
