I have had a Craftsman dado blade for years,however it does not leave a good bottom,in the dado.It is not flat,humped in the middle.I have been looking at new ones,both Freuds.One is the Freud Super Dado set,the other is the Freud Dial-A-Width Dado set.Any comments on which one of these is the best,or other ones on the market which are as good or better.My Craftsman is a pain in the a// to dial in.I would appreciate any feedback.
