Review on 💎 Diamond-Coated 4 3 X60MM Hole Saw by Ian Iknokinok

I've bought many other brands from Starrett, Lenox, Blumol and many others, all others have terrible runout and never a finished hole of the specified size. These are absolutely the best I have seen in over 40 years of metal production, almost no wear, they are amazing! Yes, I would buy it again and order a different size. Soon I will only have Diablo crowns.
