dado blades

[Larry Bush]

I seem to remember some dado blades that were only the outer two.
Turned one way they cut a 1/4 in. dado, and the other way
they cut a 7/32 in. for plywood.
Now I can't find them.
Any ideas where they are advertised/sold??

The Freud SBOX8 Box Joint cutter set cuts 1/4-Inch and 3/8-Inch grooves with the adjustment exactly as you describe. The cut is great ... very flat bottom and chip free. In my experience.
