Congrats on a new Jet table saw!

http://www.infinitytools.com/DADO-SAW-BLADES-DADONATOR/products/1194/

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.

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.

I have 2 inserts for the set, one is 1/2” wide the other is full width. The majority of the work I use them on is for rabbiting and occasional in field dadoes. When rabbiting the portion away from the fence is ZC the fence side is always under the sacrifice fence. I made a dado jig for my hand routers that’ll cut a 22” wide board with up to a 7/8 bit. Much faster than a TS set up even if it takes 2 or more passes. I find it safer to multiple dado long boards, (like shelving) with the router.

Yes good timing on dado purchase question.

I have a chance to purchase an older but unused 8” Forrest dado set.

It is not stamped “Dado King” like the new ones I see. The only marking I can see from the picture is DK64544. I see on the Forrest site their current sets are designated as DK06xxx for 6” and DK08xxx for 8” sets but this is definitely an 8” set.

Not sure how old it is. Any ideas on how old it might be and whether it would be comparable to the current 8” set DK08244?

What should I pay for a NIB older set if the new one retails at $300?

I have a Forrest 6” dado. Tiny bat wings in the bottom typical of most dado sets. I have an old router plane or whatever they are called that I use to clean out the bottom of dados when I need them to be real precise. I’ve never needed the extra depth of an 8” dado set but I could see the utility of having the extra depth.

+1 on wobble dados being horrid. They leave a concave bottom.

I made my own throat inserts in 1/4”, 1/2”, and 3/4” out of free quarter sawn oak cutoffs from my local yard. I experimented by cutting a 1/4” dado using the 3/4” insert with no noticeable effect on the quality of the dado. Go figure. Tom

Gotta pic? That’d help answer a lot of questions about it.

Hey all,

Just a quick update. I ordered my new Jet saw and after two weeks of still no tracking because of a labor dispute? I cancelled my order because I found a used Jet with all the accessories and a excalibur sliding extension table in great shape.

I have it in place and ready to go, and I’ve decided to go with the Infinity Dadonator blades.

Thanks again for all your help!

Congrats on the Jet table saw. Your order fell victim to the West Coast dock strikes/work slowdowns. Since you have already decided since I wrote the original reply, here goes anyway. If you have the dough, as it is pretty pricey, and want the very best; buy the 8” Forrest Dado King. You will never need to buy another one in your lifetime. Forrest can sharpen, repair and refurbish the cutters and chippers as needed. I saved up for mine, and have had it for several years and can highly recommend it. I have made ZCIs for my set in all of the sizes that I frequently use, plus my Grizz 1023 came with a large generic dado insert. It comes with a good set of magnetic shims to fine tune cuts, and the assortment of chipper thicknesses will let you get pretty close to most needed sizes. JMHO.

Yes, apparently anyone waiting for a Jet is going to be waiting awhile. I did check out the Forrest dado set you mentioned. The reviews were great also, but the “batman ears” on the dado cut is what swayed me to the other set. Thank you for the info though.

Have your say...
