I have used the special tool available through the various suppliers with excellent success. This tool allows you to center the rivet accuratly with a 3/16" drill bit.
You only then need to drill into the rivet about 1/4" or less. Using a heavy chisel and heavy hammer, with vise grips holding the chisel, you should be able to knock the rivet head off. Wear leather gloves and safety glasses. Remainder of rivet can then be driven out with a set punch.
