Hey folks, can you recommend a dado set for my new sawstop table saw. I’ve never worked with dado set and have no idea where to start. Appreciate if you recommend size brand etc with links if possible.

I want to use set to cut tennons specially.

Be sure to get an 8” diameter set. That’s what the brake works with. Beyond that, there are lots of very good choices out there. I’m sure you’ll get some recommendations.

One of the factors in the price of the dado set is how many teeth the chippers have. My Amana set from the 1990s is the old style where the chippers only have two cutters, one at each end. It never let me down.

Many newer ones have chippers with four or more cutters. The idea is to get a smoother cut. It probably helps, so you have to decide if it’s worth the additional cost for your needs.

I had this same issue a while back. The DEWALT Dado Blade Set, 8-Inch, 24-Tooth (DW7670) is really nice. I think I paid $135 on Amazon. it’s $155 now. It looks a lot like the Forrest. I have a Freud Super Dado set, But because of the anti kickback feature Sawstop does not recommend it. Dan

Pretty much what they said above. If money is there, one with 4 tooth chippers will cut a little more smoothly, less clean up on your tenons. I also use a Freud Super dado (sd 508). You want to avoid the Infinity Dadonator , according to SS the extra weight (6 tooth chippers) is too much for the saw and there have been reports of bent arbors when the brake fires. As for the anti kickback nubs on the Freud set…I though I read they had been redesigned to be less of a problem with the brake. Doesn’t matter, I suggest it anyway. Mine has been resharpened 3 times, and the sharpener ground those nubs off.

I have a JSS, and originally bought the adjustable Freud dado set. It will not clear the brake, as it is slightly over 8” in diameter. The brake cannot be adjusted on the JSS, it fits onto two pins. I have an Amana dado set.

Second the vote for the Dewalt. It works fantastic. Any of the Freud ones are not recommended by Sawstop as RDan said.

I’ve had 3 different sets: Freud, Amana (Dadonator sold by Infinity Tools) and a Forrest Dado King.

The Freud was a 2 wing, the others are 4 wing.

The Freud served me well for many years. Its probably the best deal out there as an entry level set. The issue (like other Freud blades) is sharpness retention. But if you’re only using it occasinally no big deal.

I can’t tell the difference between the Amana and Forrest. No question either one way out performs the Freud.

For just a few dollars more, I’d recommend the Dadonator.

And that reminds me, re: antikick back I’ve recently bought a SS and I have to go through my blades. I have a bad feeling my Freud glue line rip, which I love, is benched.

Do you need a dado set or can you install a router in the table and use it?

Do you make that many tenons?

There’s some mention of what SS said, here’s what the published on their website. Notice the wording about the anti kickback nubs.

“Further, blades with depth-limiting shoulders may take longer to stop in the event of an accident than standard blades, and you could receive a more serious injury. Therefore, SawStop recommends using blades without depth-limiting shoulders.

SawStop recommends only using 8” stacked dado sets, with a maximum thickness of 13/16”. “Wobble” dado sets are not recommended, as they may not engage correctly with the dado brake cartridge. Do not use dado sets with solid-plate interior chippers or blades with molding heads, as neither brake cartridge is designed to stop those blade types.”

Having owned, or used many different sets I feel the more teeth on the chippers the better. They give you that flat bottom you want, and the inside of the dado is always well cleaned. I never have to go back to remove riffraff left on the inside, as I have had to with virtually every other dado blade set I have ever used, including a few that cost much more.

My Dadonator from Infinity has 6 chippers, instead of the standard 2 or 4, so more cuts per revolution, which results in very smooth cuts, and has FTG blade grind.

Typically a 6” will more than cover Dados in 3/4” material. I don’t have a SS, so not sure about what is needed for the brake to get engaged? That goes both pro, and con.

I could post pics taken of dados I made, but the pic on Infinity’s site looks just like what I would post, but this is what you get. I find it interesting other brands don’t post this pic, or one like it with what their blades do, but as I’ve found they don’t do this.
