I have read some threads with people saying when they drill out stock cans they needed a masonary bit to get through the ceramic inside. Well ive done the drilling and at least in my can there was no ceramic just one layer of tin. The masonary bit finally got through, burnt the crap out of it but got through. It would have been easier with a metal bit, but they are 5 times dearer.
