I doubt it’s the blade. I run Freud blades almost exclusively, and I’ve never had an issue with any of them (which, by the way, is more than I can say for Tenryu). Seems unlikely that you would get 13 bad blades in a row and I’d get 20 or 30 with no issues.

If the blade arbor was slightly bent, you would get slight vibration with no blade … slight because the arbor is fairly light and small diameter. When you add a blade to the arbor, you’re adding a fair bit of weight and a bunch of diameter which means the vibration would increase exponentially.

My vote is a problem with the arbor.
