Hello everyone, I hope you guys are all having a good weekend. I am researching a dado set and because I am using a SawStop they recommend the following sets.

· Forrest Dado King DK0824XXX (5/8” arbor)
· DeWalt DW7670
· Tenryu GMD-20340
· King Canada KSC-8000
· Amana 658040

Which one would you buy and why? Any good or bad experiences to date?

Also, none of these offer any greater width than 7/8”...I don’t think. Is there any reason I would need a set that is bigger than that? If I ever do I can use a smaller one and run it through twice I think.

Thanks,
Roger

The DW7670 gets best bang for the buck award IMO. It outperforms the typical $100 group, and gives a taste of the best sets for a lot less. Can often be found in the $120 range on sale.

I doubt your arbor will handle anything wider than 7/8”, and even to fit the whole stack on sometimes you need to leave off the washer.

In 45+ years of Woodworking I have never cut a dado wide enough to need all of the chippers. If the Forrest is in your budget I would highly recommend it.

If I ever need a wider dado than ~3/4”, I just move the fence and make two passes. Certainly that’s easier than trying to stuff all the chippers onto the arbor.

Freud or Amana 8”. Freud is a good deal most of the time…

I use the full width quite regularly, for example when making tenons or lap joints.

Everyone says a different brand…can I ask this, forget about a sawstop, just dado blades in general; is there a brand that stays sharper longer in average wood? or because most folks don’t use a dado blade all day long does it matter? Is there one that cuts a nicer, smoother dado? Thanks for any info…

Before I got a Sawstop, I used the Freud 206 set. It was ok, but the bottoms weren’t as clean as I would have liked. I now have the DeWalt set and it seems to cut much cleaner. In fact, I had the unfortunate opportunity to run a second set on my saw and it was just as good as the first.

It’s not the different brands, it’s the price…I’ve used a lot of dado blades in cabinet shops and Freud or Amana seem to be the Norm..

Personally I use a router in the table saw wing more than dado nlades now. Rarely use dado blades…

Do you have experience with other dado blades ?

That explains. People who do use dado blades notice that Freud is quite a mediocre dado stack. A regular flat tooth blade will give you a much better cut than Freud dado. The latter produces deep notches at the bottom of the slot that are only acceptable when the slot is covered by wood.

I’ve used the Freud SD208, DW7670, Systimatic 42T Superfine, Freud SD508, and the Infinity Dadonator. Not all are suitable for use with a Sawstop due to the anti-kickback shoulders. All were pretty respectable sets. The cleanest cutting IME was the Infinity Dadonator. The DW7670 is the best bang for the buck IMO at ~ $120. It gets really expensive to compare the really good sets side by side, so it rarely happens outside of a magazine review. The Dadonator, SD508, Forrest Dado King, and Ridge Carbide Dado Master are the usual finalists amongst the premium sets.

How long a blade stays sharp is dependent on several variables including cleanliness, moisture content, heat build up, technique, material hardness, and many others, so it’s almost never an apples to apples comparison, and is tough to accurately predict or compare. A good set made from quality materials that’s well maintained should last a hobbyist a very long time.

I cut these with a Freud SD208 for this project.

These are 7/8” wide x 1/4” deep. Clean enough for what I do. I bought the set in 2010.
