I was drilling some (13) holes is a 10mm titanium plate and everything was going fine and dandy until I wore out the last 4mm (.1575") 5% kobolt drill I had. I then switched to straight HSS. It broke in the first hole, about 1mm below the surface. The plate is on a fixture of aluminium and I "can't" remove it because I am pretty sure I can't get it back on with exactly the same rotation.
How do I remove the broken drill ?
I have 2 ideas:
1. Plunge 6mm carbide endcutting endmill on top of it and straight thru. The hole is going to be 8mm in the end so I have got room to spare.
2. Build a dam of model clay and use some kind of acid to remove the drill, but what acid ?
