    • A cutting tool (10) includes at least one cutting portion(16), having an insert pocket (18), releasably retaining a single-sided cutting insert (20) therein. The cutting portion(16) has a tangential screwing element (22) to clamp the cutting insert (20) in the insert pocket (18). The screwing element, which comprises a screw(40), allows releasing and clamping of the cutting insert(20) without having to completely remove the screwing element (22) from the insert pocket(18). The cutting insert(20) has a top surface(29), a bottom surface(28), two opposing major side surfaces(46) and two opposing minor side surfaces (72); a recess (26) is formed in the bottom surface (28). The screwing element(22) is inserted into the recess(26) via the bottom surface(28). Upon fastening of the screw(40), a protruding portion of the screwing element(22) clamps the cutting insert (20) in its insert pocket (18). The cutting insert (20) and protruding portion may have respective geometries allowing them to abut one another at at least two distinct abutment sub-regions.
    • 一种切削刀具(10)包括至少一个切削部分(16),该切削部分具有刀片槽(18),该刀片槽(18)可释放地将单侧切削刀片(20)保持在其中。 切削部分(16)具有用于将切削刀片(20)夹紧在刀片槽(18)中的切向螺纹元件(22)。 包括螺钉(40)的旋拧元件允许在不必将旋拧元件(22)从刀片槽(18)完全移除的情况下松开和夹紧切削刀片(20)。 切削刀片(20)具有顶面(29),底面(28),两个相对的主侧面(46)和两个相对的副侧面(72)。 凹部(26)形成在底面(28)中。 螺钉元件(22)经由底面(28)插入到凹部(26)中。 在紧固螺钉(40)之后,螺钉元件(22)的突出部分将切削刀片(20)夹紧在其刀片槽(18)中。 切削刀片(20)和突出部分可具有相应的几何形状,从而允许它们在至少两个不同的邻接子区域处彼此邻接。
