Home Depot sells some little dinguses called “screw extractors”.
They are somewhat more robust than easy outs, which are very prone to breakage, especially in small sizes.
They are hex shanks, like a power screwdriver bit, with a short, tapered, left handed thread on the business end.
You really don’t want either a broken Easy Out or drilbit stuck in your hole!  
Some heat from a propane torch might help, if the location allows.
