Dado Track Saw?

[stoufferc]

My idea is simple.  Make a circular saw that is specifically designed to cut dados and would ride on a track.  The saw could be equipped with a 6" Fraud Dial A Dado type blade and would only have to cut up to an inch deep.  The dado track saw would be used to cut perfect dados anywhere and to any length your track will allow.  Having a dial a dado type blade would allow the perfect fit to any thickness material or plywood.  Yes a router can be used to cut dados and I have used that process but a circular blade that scores the veneer with the outer teeth would leave a cleaner cut and would cut faster and could be completed in one pass.  Yes router bits come in undersized plywood thickness but they are never perfect. And yes you can make two passes with a smaller router bit and a jig.  I'm just saying that a track saw equipped with a blade make specifically for cutting dados would be really really cool!
Thoughts?

The HK 85 is on the right track BUT does anyone have experience cutting veneer plywood with that cutter head.  Most good dado blades are ground to score the veneer and prevent tearout.

Mafell MF26cc is exactly that. There are also some older and bigger versions.
