A decent chain tool will push a rivet out without having to grind anything off. Trick is you need to get the pin on the tool dead straight on the rivet then nip it. Then gradually turn to free it. Try and do it nest the sprocket as you can use the sprocket to lever down on....failing that cut it off as said,thin blade angle grinder... 1sec later it's off
