I use my dremel to grind down the riveted part and knock the pins out with a punch. Been doing it like that for over 45 years which is how many years I been working on motorcycles as a living.
Careful though, some of those cheapos wont even break a bicycle chain. I went through a couple before I decided to spend a little more on a park tool chain breaker and I've been usin that for years now. For the 415 chain I use this one http://www.ebay.com/itm/Motorcycle-...297561?hash=item4aec418819:g:wfgAAOSwxp9W8eI4. This does the job, but there are better ones.
