Drilling through a magnet?

[nighterfighter]

The magnet is very hard,and black.

For the age of the radio- We aren't sure, it was lying in a pile of old stuff. I couldn't give you any estimation, other than 10+ years? :/

And the magnet- I'm at school now (my lunch hour) and have made some progress on the magnet. I used a 1/2 bit again, and have managed to make a small indentation. I didn't want to go to much, because the magnet was getting hot (still has it magnetism though!) so I am letting it cool down.

Thanks guys!
