Are you referring to the shell, which is part of the frame, or the cups, which thread into the shell and hold the bearings? I suspect you mean "cups."
Do the "slots" in the cup look like this?
If so, the
Park HCW-11 is the proper tool for these. People do use a hammer and punch instead, but if you do, be careful. If you bugger the slots you're in for a world of hurt getting the cup out.
