I've ordered some 1/8" center drill bits and then some LH bits. I also have easy out's once I have the hole drilled.

Are there any other techniques other than:
1. Center drill
2. LH drill bit
3. Easy out

Heat the area around what's left or the bolt (called a Dutchman where I'm from) then use a small cold chisel to back the Dutchman out. Heat is your friend
