Hitting with a hammer and punch inward may help loosen the brass. You will need to drill a hole anyway so no reason not to try a left handed drill bit. I have also used both allen drivers and regular screw drivers as an easyout. Just find a size that fits tight.
Inexpensive easyouts that are both hard and brittle are not the ones to use. The better extractors are more ductile and less likely to break.
