Review on Enhance Precision with Dremel 631 Brad Point Drill Bits by Yiorgos Reynolds

I have this SAE set and a European Dremel metric set; Neither set seems particularly well made. The grooves are a little rough, the edges don't feel sharp and the metal feels a little soft here. Revain sells a set of Danish made metric bits under the Fisch brand (Part No. FSF-134893 8). -a bunch of items) that are really very good. If the metric system is suitable for drilling polymer, for example, I would recommend it.
