I bought, over the Internet, a new 12" Freud blade to replace my Dewalt. Dewalt ought to be ashamed of themselves; the blade didn't cut properly when it was brand new, but that is off topic for today.
The Freud blade says it is for sliding miter saws. I have a non-slider (stationary?). Does it make a difference? I can't see why a slider would require a special blade, but what do I know.
