Claims

[Scope of utility model registration request]

Each of the plurality of teeth 3 is bent into a concentric hook-neck shape so that the tooth bottom 4 is offset to one side from the radial direction of the tip 6 by at least the width of the tip 6, and each tip 6 is bent to one side. A grooving cutter constructed so as not to have tooth bottoms 4 in the radial direction.
