PURPOSE: To provide an economical cutter by quenching each tooth only after forming a laminated sheet type cutter blank of SK material.
CONSTITUTION: For example, after blank layout of a sheet material 10 of SK4, a blank 11 is bored. Next, after surface polishing, the tooth form is polished or cut with a grinding wheel or formed cutter 16. The slant surface 17 of tooth 15 of a laminated sheet cutter element 18 thus formed is polished or cut and quenched by an impulse quenching apparatus 19. Since the low hardness SK material can be thus worked as it is, the workability is improved to shorten the working time. In addition, the quenching is carried out in the final process, so that the polishing can be changed over to the cutting since polishing, cutting and other process can be sequentially carried out after boring process.
