Many of us have magnetic tool bits. Sometimes you need to demagnetize a driver or a bit though to say keep it from attracting metal filings for example. Drill bits sometimes need this.

You need one of these ceramic magnets. You can order one from a magnet company, or if you have an old microwave laying around, you can scam two out of the magnitron. (Please short across the capacitor first before touching anything, it’s the silver canister looking thing with wires on spade terminals on the top). Just use an insulated screw driver and touch both ends of the terminals and maybe you’ll get a pop out of it.

Anyway the point is that with this magnet you can demagnetize your tool as well as re-magnetize them.
To de-magnetize a driver, simply pass it into the middle of the hole of the magnet, and without touching the magnet at all, withdraw it. Presto, normal screw driver. To re-magnetize, rub it on the magnet.

I know this is basic to a lot of you, but we got some young guys here who probably never heard of it.

Good tip…never knew about the microwave magnets : )

They’re very strong and will pinch you, so be careful.
