ABSTRACT:
The inner peripheral portion of the blade material is made thinner than the outer peripheral portion thereof. This serves to make greater, as compared with conventional cutter bodies, the distance between the adjacent portions of the cutter body where the respective inner peripheral portions of the blade material are adapted to rest, thus enabling the rigidity of the cutting tool itself to be improved. On top of this, the rake face of the blade material can be reground, when necessary, until the material is completely used up and worn away, thus making it possible to make full and efficient use of the blade material without any waste.
