Re: maker of small drill bits (#78, #80) for hand drilling resin kits


You name the brand or supplier of tiny twist drill bits, I've bought them. I've also thrown out a lot over the years, too.
These from Otto Frei Jewelers are my everyday bits of choice nowadays. High quality and affordable, start nicely and right combination of temper and flexibility for resin and brass.
