I have used the this ( to remove thinset, mastic and paint from concrete and it worked pretty well. You will want to have some dust collection on the angle grinder and wear a respirator too.

I tried concrete polishing and grinding discs but they did not work well to just get off what was on the concrete, they either did very little or dug in to much.

these do work best on smooth hard concrete, if the concrete is rough or soft, it will dig in if you are not careful. Also a variable speed angle grinder seemed to work best at slower speeds and the blades lasted longer too.
