Review on Vinonzi Precision Jewelry Assembling 0 5 3 0Mm by Jason Dahlkemper

The two largest bits came with almost flat points. Very badly done. On closer inspection you can also see that the small pieces are not cut properly and only appear flat. If you want to use it to drill holes in the softest metal, you're going to waste some time. Or just grab some of the best. The hand drill works well but not with blunt bits. 2 stars for a working hand drill. Otherwise it would be 1 star.
