“I’ve recently switched from Starrett to these holesaws cus they’re moar betterer. I make bicycle frames. These go through .9mm 4130 tube at high speed very cleanly and so far seem to have less run out than others. Cutting super hard steels (853) with a holesaw is always tricky but they do that a little better too. I think they’re probably as good as it gets for notching thin-wall tubing.”
