On the subject of cut offs I use Dewalts and sure they work but in each case as I use them they never last long .A wile back i found a used cut off the arbor size was to large for my chop but i aliened it and it worked and worked and i have lost count how many cuts i made and still have it. i sure wish i knew the company who made it . I think it was a worn down king size cut off as i found it in a utility company trash container.
