I was able to hold a much smaller one steady by the bell as I ground it on a plastic surface.

The smooth surface of the rotor where the brake pads hit measures 11.6 mm. The lip measures 11.8 mm. So there is a 0.2 mm difference or 0.1 mm on each side. It sure feels deeper than this but that is what it measures.
My biggest concern is that I was not able to get the brake pads out because they were getting hung up on the lip. I was not able to easily pull the caliper off either. I finally opened up the bleeder and pushed the pads back enough so they could clear the lip. I would rather not have to deal with this next time, when it will be a bit worse.
