As noted, it does work on flush rivets. The serrated nose piece bites in well, just place it firmly before you start the drill. The more expensive tool that ACS sells comes with the serrated tips; I’m not sure about the less expensive one.
It makes easy work of removing rivets; while solid flush rivets do come with a drill punch, I still use this tool to ensure the bit stays centered and no more elongated holes.
