I thought this subject was discussed already but can't find it. Maybe i was dreaming, so can you drill a hole in a ceramic magnet? I got a couple of cheap ones from PA and had a thought about some uses but need to attach them to wood. Glue might work but they will be outdoors so a stove bolt thru the middle would be the simplest solution. I could do a test i guess also, 5 bucks for 2 magnets is not going to break the bank if one shatters.

Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!
Can you drill a magnet?

Those magnets with hooks on them I think have a hole through - also inexpensive at PA.Please post if you can successfully drill.
I've used silicone for "glue" several times -- to glue house numbers onto a big rock outside our house -- 23 years and they're still there.
If there's some "stress" on them a more upscale silicone might be required -- "The right stuff" sticks like cat poo to a blanket.

Ali and Amazon sell magnets that are predrilled. They even sell predrilled neodymium.
150 pounds! Wow!
Nah, must be wrong units.

I've been looking for a water jet machine for a while now, PA seems to not be stocking those.

K&J Magnetics has a good article on gluing Neodymium magnets; should be applicable to Ceramic as well.
When drilling into hard brittle material, support is critical. You can get it by drilling a small hole far from the edge, or by adding confinement. In the same way that wrapping wood in cord or leather keeps it from splitting along the grain, some sort of clamping can make a big difference when drilling. It has to be tight and all the way around, so I'm not sure what to use for something so small. Maybe a cinch band

Maybe a hose clamp cold work.
I've had Lee Valley rare earth magnets split in two just sitting there minding their own business attached to a metal cabinet. I've also had them shed their nickel plating.
They are quite inexpensive but the magnetic strength varies. I had one in a study lamp that could barely keep it upright never mind at an angle. Probably cost you more to buy the right drill. I have some cheapo diamond encrusted annular (core) drills & they were very slow going in a 1/4" thick grinding wheel. I cant imagine the magnet would be smooth sailing.
Maybe another option is buy some 1/2" diameter (or whatever) neodymium's which are spit cheap & just arrange them in a radial pattern on a washer plate. Grout them in place with epoxy. I bet it would equate to the same result if not stronger.

Just buy them already round and already drilled. They are dirt cheap. They are even countersink to hide the screw or bolt head.
Drilling is a no go. Tried several types of drills but nothing. Just to hard, so i guess it's glue time.
Just buy them with the holes already there. They are cheap. See post #5 above. Next day delivery. Well..... maybe next week where you are......
