Claims

[Claims for Utility Model Registration] At least one end of the shank in the longitudinal direction is formed with a neck that is eccentric with respect to the shank and extends in the longitudinal direction, and a cutting edge protrudes at the tip of the neck in a direction opposite to the eccentric direction of the neck. The neck section is formed in an oval shape with a long axis in a direction substantially perpendicular to the rake surface of the cutting edge. .
