Claims (12)
- A cutting insert comprising:an upper face and a lower face;a front side face portion and a back side face portion, the front and back side face portions connecting the upper face and the lower face; anda through-hole passing through the upper face and the lower face,wherein a cutting edge is formed in the front side face portion, and the back side face portion is provided with a first inclined face and a second inclined face which are inclined forwardly at different angles, respectively, with respect to a plane normal to a rotational axis, and the first inclined face is longer than the second inclined face so that the back side face portion has a non-symmetrical convex "V" shape.
- The cutting insert of claim 1, wherein the front side face portion comprises a pair of cutting edges which are rotational symmetric to the rotational axis.
- The cutting insert of claim 1, wherein an inclination angle of the first inclined face is smaller than that of the second inclined face.
- The cutting insert of claim 1, wherein the first inclined face of the back side face portion is inclined at an angle of 5 to 15 degrees with respect to the plane perpendicular to the rotational axis, and the second inclined face of the back side face portion is inclined at an angle of 35 to 45 degrees with respect to the plane perpendicular to the rotational axis.
- The cutting insert of claim 1, wherein a portion of an inner circumferential surface of the through-hole is a flat plane which is inclined in an opposite direction to the first inclined face.
