If you want to study this subject a little more, determine what you
are going to use the dado for. If it is plywood, go for either of the
ones suggested. If you are working with solid wood, look into the
Freud 300 series positive hook dado sets.
I think my Freud d-a-d is great. With a digital vernier you can dial it in
extremely close. The cut is also very clean even with ply-board.
I am glad I bought it after all the hand wringing I did to lay out the cash
for it. Worth every penny.
Woodworkers Journal for June 2004 (Volume 28 $3) reviews about 10 different
8" Stacked dado sets including the Forrest Dado King and the Freud SD508
Super Dado. The authors conclusion:
For best value honors, my vote goes to either the Freud Super Dado or the
Everlast DS840. If spending a bit more isn't a problem, the Forrest Dado
King should offer bullet proof performance over time.
The review rated the cutting ability for Pine, Oak, Birch Veneer Plywood,
Melamine particle board, and MDF. Each was given a 1-5 rating (5 is best)
and both the Forrest and the Freud had 5's straight across.
There was also a sidebar that talked about the Freud SD608 Dial-a-width
Dado. To paraphrase what I read into it, the author said it was basically
the SD508 except one of the outer blades can be adjusted in .004 increments
(didn't say how many increments) without having to remove the blade from the
saw. He liked it.
Has to be one of the best inventions in the last ten years. I have to take
off not only the end blade, but all the chippers to reach the flat part of
the arbor or else my shims get crimped by the threads. What a pain in the
The SD608 is the one I'm leaning towards; I really like the micro adjustment
idea. Can't really fathom how it works in practice though. I'm assuming you
have to put in the right number of chippers to get the width "close" to what
you need, then micro adjust to the exact width. The question I have is how
much range does the micro adjustment feature have? The width of the adjustable
blade itself maybe (1/8")?
Anybody here actually own the Freud SD608?
Free bad advice available here.
To reply, change the chemical designation to its common name.
It comes with a chart for how many chippers to put on for the width you want
to dado. It also comes with one 3/32 chipper for undersized plywood. The
"range" is about a sixteenth inch +- or so. I've never measured it before.
What I can say is I've had the non dial shim type before and this is waayyyy
better! You definately won't be disapointed.
Here is the product description:
It would appear that you have to get close and then the dial
allows a .004 adjustment. I assume you have to be short not long
when making up the stack.

I'm running the Forrest on a General 650(left tilt). Very reliable, and
clean. A real work horse. Haven't tried the Freud-dial yet to compare, but
the Forrest is spot on. (Forrest should come up with a better storage case
