Good quality hole saws. I used 20mm to make two holes in 1/4 (6.5mm) 6061 aluminum. At the beginning it worked fine, produced nice long shavings from every tooth, but once the thees went completely inside the metal, it doesn't work very well any more. I did manage to make holes, but I had to lift the whole saw every few seconds and clean it, and I had to use lots of oil. The holes were very smooth. If you want to drill thin (2-3mm) aluminum, these whole saws are perfect. I don't know about longevity, but it was still sharp after my 2 holes.
