Quoted from BlackCatBone:OK, drill it out it is. What size drill bit should I start with? I was thinking of starting with 1/8" and going up from there, but that is just a guess. I'd like to use as small a bit as I can get away with. Would appreciate hearing from anyone who has used the drill technique. Thanks.
Just use a decently sharp 1/4" bit and lubricate it as you go. I've been using Tri-Flow that I have in a squeeze bottle because it's handy and get through one in about 10 seconds.
