    摘要： The present invention discloses a cutting insert which can be mounted stably to the small- diametered cutter with a sufficient mounting surface and has a plurality of corner cutting edges. The cutting insert according to the present invention has a shape having an upper face and a lower face being opposite to each other, and two longitudinal side faces and two transversal side faces connecting the upper face and the lower face, with a through hole passing through each central part of the upper face and the lower face. The longitudinal side faces are opposite to each other and normal to the upper face and the lower face, and the transversal side faces are opposite to each other and normal to the upper face and the lower face. In addition, each of the upper face and the lower face is provided with two chip discharge grooves extended along both transversal side faces, and the two chip discharge grooves are inclined oppositely in the transverse direction so that each of the upper face and the lower face is provided with two corner cutting edges at diagonally opposite corners. Here, the longitudinal length of the cutting insert defined by the maximum length between the transversal side faces is longer than the transversal length defined by the maximum length between the longitudinal side faces.
