Congrats on a new Jet table saw!

Dadonator comes to mind and it’s from Infinity.

or

Carbide Processors dado set works well also.

I have both but only have used the Carbide Processors one and it worked
nicely. Results:

Freud 8 inch. DON’T buy the 6 inch to save money. If you use a sled on your TS and need to make a deep dado, there is a chance the 6 inch won’t let you cut as deep as you want. I know, because I bought the 6 inch and that’s just what happened to me. DON’T buy a wobbler. It’s a total waste of money and won’t make accurate cuts.

Funny, I just logged in to ask something about dadoes.

I just destroyed my Diablo DD208 (same as the Freud SD208), but it served me well. Since I need to replace it, I’ve been researching again. I’m leaning towards the Oshlun SDS-0842 as I’ve read good reviews of it. I’ve also seen a lot of good reviews of the Dewalt DW7670.

These are 8” dadoes. If it weren’t for the fact that I use sleds with my dadoes, I’d go with a 6” to save money.

If you want to spend a lot more, there are other choices, but these guys seem to be a sweet spot for price/performance.

Good luck.

More important than brand is the design and model. The best set I’ve used is the Infinity Dadonator…tough to beat at any price. It runs around $200. Made in Italy for a US company.

The best bang for the buck is usually the Delta/DW 7670 set for ~ $120. Craftsman offers what looks to be the same set under their name, so check sale pricing for the best deal. Made in China.

The Freud SD208 is a good set for ~ $95, but the 7670 has it pretty well covered in performance, shim stock, and the carrying case. It just cuts cleaner. The SD508 is their better set with the 4T chippers…it’s cleaner cutting than the SD208 but runs in the range of twice as much. The Freud SD608 features the same configuration in with an adjustable hub…made in Italy.

The Forrest Dado King and Ridge Carbide Dado Master are both excellent sets too….both made in the USA.

The better Oshlun sets can be a pretty good bang for the buck on sale. Made in China.

Adamal – I went from a good SD208 to a better DW7670….it cuts cleaner. Lots of others have made similar observations. The DW7670 seems to have the better Oshlun 8” set covered too.

Freud 8” Super Dado (stacked version). Totally agree with Dale – buy the 8” version

I’ve had the same Freud 8” set for 20 yrs. I prefer the glue groove cuts on the outer corners of the dado, gives the glue from a proper glue up somewhere to go when clamped.

I agree with Knotscott. I use the Infinity Dadonator but have used and still own DW7670. Once I started using the Dadonator set there was no looking back. I am so impressed with Infinity that I am going to order some other blades from them.

I’ll go a different route and give a shout out to Craftsman 8” Dado stack. I had plenty of points, plus bonus points, plus leftover gift card, so it was a worthy purchase for me, plus the 3/32nd chipper helps out a LOT with undersized ply.

Lots of good suggestions! Thanks so much for the help. This poses another question…

What do you use for the dado insert plate? Do you use different ones for different widths of the dado?

Sorry, I’ve been dadoing and rabbeting with a router, so this is all new to me :)

Thanks again!

You can buy dedicated dado inserts, but it makes more sense to me to use a well worn zero clearance insert. You can keep expanding the width until you’ve reached full dado width. In time, you’ll end up with a variety of widths if you can rotating old ZCI’s into the lineup. Just make sure whatever you use is good and stiff…a flexing insert is bad juju.

Great saw choice.
Great timming on dado question. Iam in the process of making my version of a Sjobergs work bench. It requires 16 dado cuts, and I don’t know which blade set to get. The bench is only 4’ long with an end vice & a moxon ( twin screw) side vise attached.
Limited space so 4’ fits my needs (at present) I cut the dado by nibbling away each dado. Very timely. With a chisle & rasp I made some very acceptable fits.
I still am undecided on a dado set because I don’t have any project that call for dado ( yet) who know.

To all that posted. A big thanks it helped me emencely limit the choices.
Aaronwood let us know what you get!
Very informative post thanks.
Mike

Only one I’ve ever used is a Freud 8” set.
Since I had it sharpened, one of the chipper is slightly deeper which is a bummer.

I would check out CMT. I’ve had very good luck with their blades.

I have two Forrest City 8 inch dados but I can’t recall the model. It’s their main standard dado set and they have worked well for me.
