How do I drill a hole in a magnet?

I often wonder how people come across threads this old. Were you searching the Dope for or “magnet drilling” or what? Curious minds (or at least one) want to know.

Hard drive magnets are steel backed rare earth magnets. I collect them for various purposes. Once you’ve used a wood chisel to knock them off their backing, they are quite brittle. If I wanted to drill a hole in one, I’d do it with a low speed diamond bit, with the magnet immersed in water to keep it cool. Small diamond bits aren’t all that expensive as jewelers use them. I’ve used them to drill holes in glass lenses as well as stones. The underwater bit is important. Heat buildup is not good for magnets or drill bits.

I wonder if the cat is still waiting?

It would be an unusal cat if it were still alive.

And possibly an unusable one :grinning:

I’ve had cats live to 18, though, so you never know.

I started reading this thread thinking it was current (like I always do :man_shrugging:) until a suggestion was made to try Radio Shack. THEN I looked at the date.

I too wonder how certain old threads get dredged up.

Yeah. Our current cat overlord is 17, bless her sweet teeny tiny gray head.

But it’s unusual.

I really wish @bat312 had told us why his cat wanted a hole in a magnet. I asked my cats if they could think of why some cat would want such a thing and the little girl smiled as if to say that she knew but wasn’t telling. Her brother just kept on washing his ear. He’s not the sharpest knife in the drawer, so he probably had no ideas on the subject.
