Kink.com comes to mind.They used to have a rough gangbang series, that has sadly retired for the most part I think. Check out the one with Jessie Rogers, for example. That's quite rough.
Outside of that, Angelo Godshack's videos he puts "domination" or "humiliation" in title are pretty brutal/manhandle-ish. Check out Nela Decker or Sasha Beart scenes for example, like where they get tossed around, and a baseball bat.
Then there's a few one off girls that do pissing/slapping/getting roughed up a little more extreme than the average actress. For example, like Anastasia Mistress.
