I'm looking to buy a 8" 5/8 arbor dado blade set.

I have it down to these three companies:

Freud SD508
Infinity Dadonator
Amana 658060

I've read the reviews and they mostly seem to be all good. Anything from you guys? Just go with the cheapest of the three and call it good?

I don't foresee cutting a lot of melamine. I have a new project that will require a bunch of mortise tenons in walnut that will be highly visible. Want / need a flat bottom cut on the mortise. Would like / need them to be sharpen-able.


Cheers,
