Even when removing the washer I can only fit up to 5/8 inch. I am noticing that most table saws come with a 5/8 arbor. Does the 5/8 arbor size indicate the dado capable width or is this the diameter size ?

5/8” typically is the diameter of the arbor.

Is this a benchtop saw? If so, it can probably only take 1/2” of a stacked dado by design.

Quite often, these saws are direct drive or have a motor that is too small to handle the load of a wider/heavier dado set so the manufacturer intentionally provides a shorter arbor.

the arbor diameter is 5/8” which is common on most 10” saws.

the max width of dado one can fit on the arbor varies between saws, and is usually stated on the specs of the saw. this depends on the LENGTH of the arbor, and not on it’s diameter.

I faught with that problem for years with my old saw, the only solution I could come up with was a new bigger, meaner saw.

Depending on your saw it is possible that you are not supposed to put a dado on it. My old mastercraft maximum did take a dado but max 6” blade with a max 1/2” stack. My buddies mastercraft (not labeled maximum but looks almost exactly the same) is not designed to take one although it has the same size arbor. I don’t have the saw anymore se we could not compare motor specs. Best thing is check the manual, if you don’t have that, I would not go over 1/2” just for safety reasons.

Thanks, everyone. Though I didn’t ask the question, dados were on my mind. I didn’t check any specs because I can’t afford a true shop saw yet, however, I do have a set of chippers (which I never used).

I have a craftsman 137.248880. I did find in the manuel where it shows a 1/2 ” dado on the spec sheet. I did remove the washer and fit a5/8 ” which I used on a sacrificial fence to cut a bout a 1/2 ’ dado for a toung and dado drawer .
