Side grinder with grinding wheel works great. Think the couple I bought were made for concrete. Worked like a champ.

Thanks. I actually did use a grinder with a diamond cup wheel for the areas where I had to grind away portions of the original slab and when I had to remove a lot of the self-leveling concrete, rather than just small ridges and bumps. Diamond wheel definitely does the job, it’s just harder to get a nice flat surface, usually had to come back and skim coat it afterwards. Plus the dust collection is zero, so I’d get about 2 seconds of visibility before I was grinding blind.
