This is overkill. There is no need to file or Dremel the pin before removal. A decent chain tool will easily remove a riveted pin from any chain if used properly (i.e. aligned over the pin). I have a Park CT-3 that has cut dozens and dozens of chains to length over 25+ years and has never needed a new pin. I carry a very small chain tool on my bike but have only used it once and that was to help another rider who's chain was improperly installed initially.
Carry a quick link for when you really need a road-side chain repair.
