| Abstract | A cutting tool and a holder-carrying tool which are capable of lowering the roughness of a surface to be finished (smoothing a surface), during a cutting process are disclosed. A cutting tool is provided on a side portion (on the side of a flank) thereof with a flat drag, which is adapted to remove the ridges and valleys of a surface to be finished, extending between: a terminal end section at which a curved surface of a nose portion terminates; and a flank. Namely, on the inner side of a tangent at the terminal end section of the curved surface of the nose portion, the flat drag is provided in the range of a flat drag angle of 0<theta<5°. A width (w) (viewed from the side of a rake face) of this flat drag is in the range of 0<w<=1.5 mm. |
