Before I ruin this by experimenting I wondered if anyone here has drilled a hole in a magnet successfully. I need to put a 5/16" hole in this one and thought about starting with a small bit and incrementing my way up?
i had the same scenario u goin through i think. i had magnets come out of a $53 stabila torpedo . i tired to drill, but couldnt. ive seen torpedo magnets w/ holes through them though
Home Depot has some Neodymium magnets with the right size hole in them but they're too strong for what I need. Guess I'll just start with my smallest bit and work up.

Some magnets are Cobalt , now that would take some drilling .
Some however are iron .
There's some of those over at Home Depot with the right size hole in them. But they're too strong for what I need it for. Guess I'll just start with my smallest bit and gradually go up. Don't know what it's made of, just some cheap magnet so maybe iron.

When a magnet is too strong, I often coat it with a layer or two of duct tape.

A lot of the jewelry crowd uses micro core bits and other assorted diamond covered tooling. you could also rig up a redneck EM setup and bore through with electrical
Thinking about those ones that were available with the hole, but too strong. How about a variation on the duct tape idea, and coat them with fiberglass resin? Can't you weaken a magnet by dropping it? Not sure how many million drops that would take if you wanted it to happen though...

To drill a hole in a magnet, you will need to apply the tip of a power drill onto the surface of the magnet and gently push it down into the center. For the best results, you should proceed with frequent stops to flush the holes with a coolant solution to prevent adverse effects.
