Ok, maybe I am missing something. I kept hearing about no need for a 8" plus dado stack so I bought the 6" SD606. So I am looking at this thing and the dial is only about 1" less than the blades outer diameter. Take away ZCI thickness and this thing will hardly get through ZCI before the dial is going to hit ZCI. What am I missing here? How could anyone use this blade with any form of insert?

All stock photos, even the one on Amazon, shows the SD608.

So assuming this set is as pointless as I think that it is, what should I go for? SD608, Dado King or Ridge Carbide Dado?
