Re: Drilling through a magnet?

We do this at work, it's not that hard if you have a significant investment in the right equipment....

The right equipment being diamond tooling for processing ceramics.....

As someone has noted, the magnet from a radio is most likely a ferrite type material (blackish), which is a high temp fired ceramic. The stuff is hard.

Also, you need to use liquid cooling, magnets do not like to be heated up. They tend to become ceramic paperweights. Google "Curie Temperature".
