No, it does not remove the crimp but it is robust enough to punch primers out without the decapping pin needing constant replacement.
I've never tried 5.56 on a regular decap setuo, but the milsurp .30-06 cases would break numerous decap pins.
God forbid a Berdan-primed case...
I remove the crimp with a chamfer tool, but enough people talk about the Super-Swager that it's something I might think about, 'specially in auto-eject.
