Excuse me. I used a lot of taps around 500 yen including Mr. Monotaro, but it was not talked to me as it was broken and I was at a loss. Although the price is nearly three times, since there is no point to be squeezed, it seems that people in the processing industry know how small the small diameter tap of stainless steel material is severe to trial, but it will crackle. Although it machined nearly 200 with one, it seems to be still sloppy. It was impressive that the cutting edge is distinctive. All of the taps were decided inside the company the other day to use this kind all. Thank you.
