Hello to everyone and Happy Holidays! I have a Grizzly G0691 table saw which has a 5/8” arbor bolt. I have no problems sliding 10” saw blades, regardless of manufacturer on and off of the arbor bolt but I do have problems with stacked dado sets. My first stacked dado set was a Freud Diablo set purchased at HD and the blades and chippers were so difficult to put on and off of the arbor bolt that I began wondering if during manufacturing of the set, the 5/8” hole in the blades, cutters and shims were a fraction too small. I then bought a cheap dado set just to see if those blades would go on and off of the arbor bolt easier. I had the same issue. I just watched a video clip of a guy putting a stacked dado set onto his table saw and it went on smoothly, just like a normal saw blade does. My question is, is this normal for all dado sets, is it the arbor bolt or is this typical only with lower end dado sets? Thanks in advance for your replies. Rob

I would use a set of calipers and see what’s what.

Freud and Grizzly are held in high regard, this should be interesting.

I have a Ridgid saw, and 2 dado sets. The cheap Mibro set slides right on and off. The Forrest set, is a bear to get off. I feel your pain. Seems like the arbor hole might be too small on some blades, would be my guess.

If a number of sets are not going on easily, odds are the saw arbour shaft is a tad too big. I would use a quality calliper/micrometer and check. If so, I would simply run the saw with NO blade on and use some emery cloth to take a tiny bit off. It shouldn’t take much.

Might also just be a tiny burr on the shaft.

Thanks for the replies. I did some additional research and read many posts about how tight dado sets fit and found out that it’s a good thing. Good sets are made that way to provide a flat bottom. Sets that go on and off as easily as a normal blade would have too much slop and create an inferior bottom. I guess on the cheap set I bought, I got a fairly decent dado set because they go on and off with just as much difficulty as the Freud set!

I have a Ridgid R4511 saw and a Freud dado set. I’ve also found that the regular saw blades go on and off rather easily, but the dado blades are a bit tighter. Not sure how that helps your situation, but it seems like a typical problem with dado sets.

I’ll just offer that you want a tight fit. a chipper or blade floating around on the arbor (even a little) is going to make you a very unhappy camper in the results. with time the holes will wear to the point where mounting/removing will get easier. several people have posted here about speeding that process up with careful filing/reaming…I would not attempt it because I lack the equipment to make sure the holes stay centered.

On occasion, I’ve had some single 10” blades, including a stacked dado set that was more difficult to get on & off than others. It’s likely just a random thing, but some are definitely tight. You can hit it lightly with some fine sandpaper to help it fit more easily if it’s super tight, but don’t over do it.

The arbor on my 30 year saw measures 0.6233 inch. Freud saw blade hole measures 0.6254.
Dado set hole measures 0.6246.

I agree with others, no slop in the dado blade.
