Review on 🔪 Cutting Edge Stainless Aluminum: Unstoppable High Speed and Durability by Warrick Dembo

I have literally dozens of hole saws so I was hesitant about buying them, glad I did. You need to drill 2 22mm diameter holes in a rusty 3/16 corner, with the pilot hole right next to the thick weld that often hardens the metal. The hole must be clean and tidy. Yes, I blued and fried it, but what a test! Got 2 super clean perfect holes! Used a 24mm and made 6 holes in the same rusty corner where there is no weld and it didn't bother him! Each comes with its own mandrel, center drill and Allen key for set screw and in separate knife boxes. with the printed size for $2 each?! Jump, they are great! Super sharp super fast cutting.
