A decent dado set will come with shim kits to correct that problem. My Dado
King set came with shims and I have never had a problem cutting a dado to
any thickness, metric, imperial, or custom.

I have the Delta 35-7670 8-Inch Stacked Dado Set that Amazon carries
(there is another set by DeWalt which looks identical) and it's worked
really well for me. I haven't used it much, but I used it to put 1/2"
grooves in some pressure treated SYP, and they still work fine on oak.
I have a 35+ year old 9" Delta contractor's saw, and even though my
saw may be underpowered for the blades, it still cuts great and gives
me a nice smooth bottom.

The included shims are metal, which I like, and the case is nice. It's
a plastic "brief case" style case with secure wing nuts to hold the
blades and chippers in place, and the shims are in little plastic
pockets in the case.

Something to consider about the "look a likes" that cost less. While they
look like the more expensive brands and may start out cutting pretty good,
they probably use a less expensive carbide. The Forrest blades use a top
quality carbide that holds it edge for a very long time. A cheaper set that
cuts pretty good may not be so cheap if you have to have them resharpened
more often.

First investigate.

Plywood is metric and doesn't fit many dado blade sets.

I think I got one from De Walt that was filled with lots of
thin stacker's and contained a many chipper blades.

I can match anything with it. Be cautious - a good buy might
not fit todays wood that is coming from Chile or Canada.
