I have a PCS175 and I use a Freud SD208 8” professional Dado. It works well, but it is not flat bottom if that is a requirement for you.

Why can’t you use it? I’ve used it many times and it works great. (It’s just not a flat bottom – there is a tiny shoulder on the edges of the dado. )

It does require the dado brake cartridge, but any dado blade in a sawstop needs to use the dado cartridge.

I’d go with the DeWalt/Delta 7670 set. It’s 8”, is the best performer under $120, doesn’t have full chipper plates so poses less mass for the safety brake, comes with a great carrying case, and excellent shim stock.

Here is the info Highland has on their site

Selecting a Dado for a SawStop Table Saw

SawStop’s unique safety mechanism necessitates that you select a dado carefully. See our guideline below for assistance.

SawStop Dado Do’s
When using a SawStop JobSite Saw, check the diameter of your dado set. Not all dado sets that are labelled 8” are actually 8”. You need to measure to be sure. The Jobsite saw cannot use dado sets larger than 8-1/16”.
When using a SawStop Industrial Cabinet Saw, Professional Cabinet Saw or Contractor’s saw, make sure the gap between the blade and brake is set correctly. (See your manual for details.)
Blade Shoulders
Dado Blade “Shoulders”
SawStop Dado Don’ts
Don’t use a wobble dado on a SawStop Saw.
Don’t use a dado with full plate dado chippers.
Don’t use a dado that is larger than 8-1/16” in diameter on a JobSite Saw.
Don’t use a dado with “shoulders” (depth-limiting or anti-kickback devices behind the cutting teeth of a blade). Dados with “shoulders” will take longer to stop in the event of an accident and could result in more serious injury to the operator.
Dados to Avoid
These dado sets are not recommended for use on SawStop saws

Freud SD208 8” Pro Dado Set — has “shoulders” and exceeds size requirement for the Jobsite Saw
Freud SD508 8” Super Dado Set — has “shoulders” and exceeds size requirement for the Jobsite Saw
Freud SD608 8” Dial-A-Width Dado Set — has “shoulders” and exceeds size requirement for the Jobsite Saw
Diablo DD208H 8” Dado Set — has “shoulders” and exceeds size requirement for the Jobsite Saw
Oldham 8” 12T Dado Set — has “shoulders”
Recommended Dados for use on SawStop Table Saws
These dado sets currently meet the recommended specifications for use on SawStop saws

Forrest 8” Dado King
DeWalt DW7670 8” Dado Stack

I just sent SS an email asking for their input, as this is the first I have heard about using or not using specific dado sets with SS saws. Will post again with their answer—-

My solution for this is to simply use a flat top blade (which I have yet to purchase). I don’t make (or foresee making) enough dadoes to justify buying a new dado set and the additional dado set brake. But that’s just my take on it.

I use the Freud stacked set on my PCS. It was what I had for my previous saw. It works fine, however I guess it will not stop as fast as other blades. I don’t use it very often, twice in the last year, so not going to rush out and buy a “more” compliant set.

Just about all dado sets that will fit the arbor will cut grooves on a SawStop saw, but their concerns are two-pronged – One concern is overall mass, and that it’ll take longer for the safety brake to stop the mass of a heavy full stack that uses chippers with full plates (like the Systimatic, Oshlun/Avenger, MLCS, Grizzly, HF, and others)....you could probably safely use a partial stack of any of those types of sets. The other concern is aimed at sets that use an anti-kickback design…they have protruding shoulders or fingers that follow the tooth that will also interfere with the safety brake. Those sets include Freud, CMT, Infinity, Amana, Irwin, Avanti, some Oldham sets, and others. All of these sets will cut dados, but when the time comes to save your fingers, they pose a problem.

Here’s a set with an anti-kickback design: (not the humps behind the teeth)

.

Here’s a set with no anti-kickback design: (this set also happens to not have a full plate chipper)

There are only a few sets that won’t interfere with the safety brake of a Saw Stop saw….Forrest, Ridge Carbide, DeWalt/Delta 7670, Tenryu…there are likely others, but am not sure off the top of my head….add to the list if you can think of some.

As usual, Scott has the skinny. They ask you not use the ones with anti kickback. That doesn’t stop me from using my Freud set on my ICS…and it cuts fine, though I’m sure the brake might not like it if I ever set it off. When I was looking for a used SS, I went to see one at a cabinet sop for sale that was only used with a dado stack. The owner told me they had set it off 3 times, and it always stopped dead in it’s tracks…they’re dado sets had the anti kickback design. So while I’m sure there is good reason not to use the anti kickback sets, I also suspect some of it is legal CYA.

I understand the full size chippers, at least for wide dados, but why would the wings hurt the Sawstop functionality?
