Can I put a 8" Dado set on a 8.5" Dewalt RAS?

[Wade Lippman]

All I want a RAS for is to cut dados. There is a really cheap one, rather rusty, available; but it can be locked at 90* and goes up and down, then who cares. But will the dado set fit?

[Matt Day]

Not sure I totally understand, but yes, an 8” dado can go on an “8.5” RAS - likely really a 9”. Might be underpowered.

[Warren Lake]

they have negative hook dadoes, would work better not pull and cut cleaner

[David Kumm]

Is the arbor long enough and does the spindle seem tight? How wide and deep do you intend to go? A 5/8" arbor has limits. Dave

Another thing to check is clearance of the blade guard, may not be able to get a full 3/4" width with an 8" dado stack. If not, would it work with a 6" stack? Or is there a dado guard available.

Are we talking an old MBF? I wouldn't sling an 8" on there, but it should spin up a 6" dado stack. The arbor and the power are going to have their limits.
