Re: Drilling through a magnet?
I just want to add a point about possibly using a plasma cutter. If you get the magnet too hot it will start to lose its magnetism. Think of it as being lots of miniature magnets all facing one direction, but when you heat it up, the particles shift and they won't all be facing the same direction. They will be slightly off parallel and the overall field will be weaker.
I know this doesn't help with cutting. I have no experience with hardness and such, I can just tell you heat is bad for a magnet.
