Man, I know how much that must've hurt. It's pretty scary too when it all goes wrong at high speed....
Your tips apply to any large ended burr, not just core drills, but hollowing/coring out largish pieces of stone is definitely one of the most potentially dangerous situations. In fact, I think I posted on my own experiences earlier in the thread :blush:
Use a drill press whenever possible, and if you're trying to hollow/dish out a form, I highly recommend using the point carver with 6mm shank burrs which are pretty much unbendable. They also work in some handpieces (heavy duty dremel has a 6mm collet).
