As one reviewer has already noted, the dial a width dado by Freud is a bit of a challenge to tighten on the Dewalt 746 hybrid saw. But it is worth the hassel. You cannot use the supplied wrench, and your saw wrench will not fit either. I found that a big ol craftsman combo wrench works just fine to tighten the nut. The "box" end grips just enough to allow you to tighten the nut perfectly. It is worth the extra effort. This is absolutely the best dado I have ever used. Even cuts across grain in veneer plywood are clean and have no tearout, and dadoes cut in hardwoods are things of beauty. Adjustment of the cut is fast and easy, and if you keep a "log" of settings, you can return to a particular cut with confidence that it will duplicate the last cut. Hard to do with shims.
