    摘要: A tool for chip removing machining includes a holder and a cutting insert clamped within a pocket of the holder. The pocket has upper and lower sides, and the cutting insert comprises an upper surface and a lower surface. The upper side of the pocket and the upper surface of the cutting insert comprise first cooperating contact surfaces defining a first flank angle. The lower side of the pocket and the lower surface of the cutting insert comprise second cooperating contact surfaces which define a second flank angle. The first flank angle is larger than the second flank angle. The lower surface of the cutting insert and the lower side of the pocket form intermeshing projections and recesses which define the second contact surfaces.
