Made a simple cut through a 2" stainless steel tube with my Tube Notcher, not what I expected, sometimes you just don't know what to buy online these days
This hole saw does an excellent job cutting 2 inch 40 gauge steel pipe. I made over 50 cuts, mostly double cuts, before breaking enough teeth to need replacing. about 3 times longer than another brand I've used. Now I'm going to buy Starrett!
