To solve a problem that conventionally used cutters for cutting work cause big impacts and vibrations at cutting time, thereby breaking cutting-edge tips from time to time, and requiring improvement in a working environment because of loud noise.

Many cutting-edge tips 3 are attached to an outer peripheral part of thin disk-shaped base metals 2 at small array pitches. One machining cutter A is made by laminating many of thus constructed multi-edged cutters 1. A cut peripheral surface drawn by the cutting-edge tips 3, 3 in these many multi-edged cutters 1, 1 forms a smoothly continuing cylindrical shape as a whole.
