I learned the hard way, but this blade is not actually 10", it's undersized by 3/16 of an inch. What that means on a sliding miter saw(or at least my saw) is it won't cut thru a 2x4 without moving the saw fence toward the user AND using the slide.  Every saw I've ever used will cut through a 2x4 just by bringing the blade down while the slide is locked. I called Freud and they admit the blade is "metric" and slightly undersized but have never heard of the situation I described.  Oh well, returned the blade.
