Hi guys,
I recently purchased this table saw off of craigslist:

I am looking to add a dado set to my blade collection. I noticed that the manual says not to use a dado larger than 6”. Im assuming this is due to the power of the saw but wanted to ask if any one has had experience with larger dados on a saw similar to this one…

Be afraid. Be VERY afraid of a dado head larger than 6” on that saw.
6” is all I use on my G0444Z table saw. You’re spinnin’ a LOT of metal, so think of a fragmentation grenade on any bench top TS.

I have the same saw. The limitation per the manufacturers manual says Maximum dado width is 1/2 in. and do not use a dado with a diameter larger than 6 in. Having got that out of the way, as long as the hole is 5/8ths for the arbor you can put what ever you want. The logic to this is that in reality you won’t need in most cases a dado blade that is more than 6 in in dia. since you won’t be cutting extreme dado channels. I do know from my saw that the 1/2 thickness is for the dado stack is predicated on getting the nut to engage and have at least a thread showing. So the dado package that I bought at Sears I can’t use all the blades together because of the width restrction. But I have found a new use for my old circular saw blades. I have taken a couple so far and used them like a dado blade. I hope this helps!

My saw can spin an 8” and is limited to 13/16” width so I bought a full size set.
I feel I wasted money because the 6” set would have done any dadoes I want.
In fact, most of the time I just leave the combo blade in the saw and make multiple passes rather than fool with changing out blades.

I bought an 8” and it was a big mistake. Saw handles it OK, it’s just that I can’t imagine ever needing the extra 2”. (Never thought I’d ever say something like that)

Mee too Gene & Crank. After I got the 8” set I wondered why did I get that. I cant ever IMAGINE cutting a dado deeper than 1/2” anyway!

Unless you have a constant need for dadoes that are more than 3” deep , you’ll be wasting your money.
I would never put an 8” set on a benchtop saw due to its mass alone. I always felt that my benchtop Delta was nothing more than an upside down Skilsaw surrounded by plastic , and the throat plate was nothing but a piece of stamped tin at the time. Follow your owners manual : )

The safe bet is to follow the manual. I’d upgrade the regular blade while you’re at it….the saw’s performance is only as good as the blade, and it’s capable of better than what’s on there.

I have a 1998 model Jet 3hp cabinet saw and the owners manual says to use a 6” dado. The 6” is big enough for me although I have wondered why an 8” would be too much for this saw. Any thoughts.

I prefer 8” dados for one reason… SLEDS! Miter gauges suck… Most sleds of decent size have a 3/4” bottom, so, once you add the table thickness and sled floor, you sometimes need the extra wedding tackle to reach where you need to reach.

That said, I’d never put an 8” dado on that saw.

Thanks guys!
I will be purchasing the 6” dado, I really appreciate all of the advice.
Looks like I’ll save money not purchasing the 8” as well, nice bonus.

I have used the 8” nearly full height on a number of occasions, but I could see how someone could never need that much. Taking off that much material takes a lot of power, something a but lacking on these saws. I would agree that the 6” for that saw would cover your needs.

Have your say...
