I am looking for an 8” dado stack for my TS and was wondering what you guys might recommend?

I bought an inexpensive CMT 12 tooth set at Lowe’s a week or so ago that was on clearance for $76, but when I got home and checked their website for reviews most said that their set had an oversized chipper that left a groove.

I think I will return it unused and look for a higher quality set.

As I don’t do a ton of work at this point requiring dadoes I would like to be more in the $100 range.

Any help would be appreciated.

Knotscott you out there?

I bought the Freud SD508 8” Dado Set about 12 years ago, it was pricey but well worth it!

I’m very happy with the Delta 8”. Bought it through Amazon for about $100 with free shipping.

Cato, I have the cheap HF and I am very satisfied with it. It cuts clean and flat bottom.
You could try it and return it if you do not like it.
I also have another more expensive set bought on Amazon, which in opinion is not working any better.

Hi Cato – At the high end, the Infinity Dadonator is the best set I’ve used to date….very impressive….I’ve literally struggled to tell the entry from the exit on several occasions. I’m sure other precision sets like the Forrest Dado King, Ridge Carbide Dado Master, or Freud SD508 are excellent too, but of the precision sets, only the Dadonator offers 6-tooth chippers. Number of teeth isn’t the only factor that influences cut quality, but I can’t help but think that 50% more teeth on the chippers of the Forrest, Ridge Carbide, or 508 would help them cut cleaner too. (Save $10 With Any Purchase Over $125 – Use Promo Code ”WINTER12” Today!)

For under $100, the Delta/DeWalt 7670 set gives a taste of the high end sets for half the cost….has a similar design to the Forrest. Nice carrying case, nice shim stock, well designed, well made, but is made in China.

I went with the oshlun, about $75 or so on amazon. I think it does a great job for the price. Its gotten good reviews on here as well. The box it comes in isnt a nice wood or plastic, its cardboard but I dont care. Its held up and if need be I can make a wood box for it. It makes a nice flat bottom and the ears are very hard to see on the outside of the cuts. Again for the money I think its a better set then the frued for about the same price. The delta/dewalt I havent used but its about $30-40 more and it doesnt do that much better from what Ive read. Good luck on finding a dado set.

I’ve been using a Delta set for several years and have no complaints. It came with an extra “under-sized” chipper to accommodate undersized plywood and several cardboard shims that allow for fine-tuning. I suppose that is standard in any brand now but I don’t know since I haven’t shopped for one recently. Very important to have though since most 3/4” ply is no longer 3/4”, 1/2” no longer 1/2”, etc.

You know you can get a router bit with a bearing that cleans
out and flattens dado bottoms. See you’ll have a hard time
pressing a board perfectly flat on your TS so the depth of
the dado will generally vary a bit anyway. Would you rather
have the edges of your dado be a bit deeper or the center?
If you say “neither” you may be chasing a costly ideal.

For truly flat-bottomed, consistently depthed dados
shops that do a lot of dados often turn to a panel router.

But in any case, the Forrest is probably in the top class
and Freud cutters and blades are always a good value in
my experience.

Do you really need an 8” dado? 6” dados work just as well and are cheaper. I don’t use dados often, so I have the HF set. It’s cheap and works for me.

I have the Systi-Matic set and got a set of magnetic shims for fine tuning the setup – although my last few projects have all used full 3/4” sheet goods. I really like the magnetic shims because they don’t try to drop slightly into the arbor threads during setup and foul things up.

I always wonder why people are so adamant about flat bottoms. One of my chippers is slightly off and I get a slight (~1/64”) groove in my dados. So what?? I use dados for carcass construction and then add faceframes. That tiny groove never sees the light of day, anyway. Even if it wasn’t hidden, it takes a very close inspection to see it.

sawkerf…magnetic shims??? the cardboard ones I got with my Delta set are about the thickness of a 12 pack beer box and the center hole is tight on the arbor (hint there for anybody wanting to make their own)...I use the same material for shimming door hinges when somebody has a problem…add as many or few as you need…

I’ve never seen a “groove” but from time to time I’ll see a “ridge” (at the location of the cardboard spacers which I could easily remove with a finger nail).

“Groove” in your range underestimates the power of today’s glues (not that you even need that excuse with 1/64” which nobody would notice with or without a face frame). Ridge is easily handled with a chisel (and I do that anyway…a pass takes all of 20 seconds or so).

I use an Amana for doing cabinetry and fine finish work and I have another set on my RAS that I bought used from a shop I used to work at when they closed up shop. I wish I could find the brand cause it’s been a real bruiser for over 18 years.
