Like Larry said, it will reduce your depth of cut....about 3/4 of an inch. I doubt that you will see a difference from your old saw, as far as the cutting you do goes.
And I've always heard that the Hitachi 8 1/2" slider is a sweet saw too. Part of the reason I got my Hitachi 10" slider. But as long as the arbor size is the same, and I'd bet it is, you should be fine. Jim.

At a minimum, I'm Pentatoxic...but most likely, I'm a Pentaholic. There seems to be no known cure. Pentatonix, winners of The Sing Off, season 3
