    Abstract: The holder has a first surface and a second surface. The head includes a cutting edge portion and a shank portion. The holder is provided with a first hole and a second hole communicating with the first hole, the first hole extending in a third direction inclined by a second angle relative to a second direction extending from the second surface toward the first surface when viewed in a direction parallel to the axis line. The shank portion has a flat surface portion, and is provided inside the second hole. The fastening portion is provided inside the first hole, and is in contact with the flat surface portion. In a plane perpendicular to the axis line, a third angle between the second direction and a fourth direction perpendicular to the flat surface portion is larger than the second angle. The third angle is less than 90°.

    Abstract: An indexable cutting insert comprises a flank face having a generally parallelogram shape and a plurality of side faces. The flank face is bounded by a plurality of edges. Each edge joins the flank face with one of the side faces. The plurality of edges comprises a first cutting edge and a second cutting edge. The first cutting edge has a shape corresponding to a portion of a first bent curve and the second cutting edge has a shape corresponding to a portion of a second bent curve. The second bent curve is obtainable by a translation of the first bent curve along a width direction of the cutting insert The cutting insert has a two-fold rotational symmetry with respect to an axis of symmetry that is perpendicular to the width direction, a longitudinal direction of the cutting insert being perpendicular to the width direction and the axis of symmetry.

    Abstract translation: 可转位切削刀片包括具有大致平行四边形形状的侧面和多个侧面。 侧面由多个边缘限定。 每个边缘将侧面与其中一个侧面连接。 多个边缘包括第一切割边缘和第二切割边缘。 第一切削刃具有与第一弯曲曲线的一部分对应的形状，第二切削刃具有与第二弯曲曲线的一部分对应的形状。 第二弯曲曲线可以通过沿着切削刀片的宽度方向平移第一弯曲曲线获得。切削刀片相对于垂直于宽度方向的对称轴线具有两倍的旋转对称性，纵向方向 的切削刀片垂直于宽度方向和对称轴线。
