Drill a hole through a ferrite magnet?

[atgcpaul]

Have some small round (1/2" diameter) and rectangular (1"x2") ferrite magnets I want to drill a hole through. I think they are ceramic. Are these just going to shatter if I try to drill them with my regular wood bits?

Long story:

My house rises/falls every winter and this prevents the shower door from staying shut. There's a magnetic strip that runs the length of the door and the frame but it's not doing its job. I wanted to supplement it with these stronger magnets. Maybe someone else has a suggestion. Right now we use an inverted clothespin to hold the door shut while we're in there. As you can imagine, neither of us are a fan.

Don't know about drilling them, but I would bet that they would fall apart into pieces. I've broken a few just dropping them on a hard surface.

Might check out some of the cupped rare earth magnets:

or the ringed ones:

Can't drill - they will shatter.

Glue magnets on the surface as needed.

Glue magnets on the surface as needed.

Or buy magnets that already have holes in them.

Use double faced tape.

I think they'd shatter as everyone said. YOu can buy very strong neodymium magnets, round or square in various sizes on ebay with straight holes or countersunk holes of various sizes.

Do they still make the magnet tape on a roll with psa on one side? That might solve your problem.

Got an old/dead computer hard disk drive? There will be a few thin but strong magnets inside it, usually with teeny screw holes.

drill a hole in a magnet?

Someone else suggested gluing them on, you could adhere them with a spot
of liquid nails or some other strong construction adhesive, that stuff works when
other things won't!

Hot melt glue works pretty good.

here is a thread on gluing Neodymium (ND) magnets
I didn't have much luck with hot melt glue.

There are different types of hot melt glue sticks. They aren't all the same. Your wood may have been oily, or like you said you didn't let it cool enough. Like I suggested in your thread either a two part epoxy or CA may work.

You might also try GE silicone II. I use that to assemble aquariums, and it seems to stick pretty good to most clean surfaces. It's tough to clean up. Once dry it can be razor bladed off. I haven't found a chemical that will dissolve it when it has cured.

I already had the ferrite magnets from HF. When I'm in the shower, I can put one on the inside of the door frame and the other on the outside of the shower door opposite from each other. There is enough attractive force to keep the door closed. I just have to remember not to push the door open before I remove the magnets or they'll fall to the ground.

I decided to double stick tape them (just need to find it in my garage mess) to the door. If the tape doesn't work out, I've got two part epoxy.

Yes, it's ugly but it's temporary until we remodel our bathroom.
