I've done it many times, especially in drivers that initially accepted long shaft bits only. Using several magnets superglued to each other to build up the space, I could then use shorter 25 mm bits instead.

I love that idea!!

If you already have a bit with a magnet glued to it, why not keep using it to check the polarity of the magnets in other bit drivers? Then just test the orientation of the new magnet you need with the "test bit".

That’s some good thinking

And if you make a mistake and the magnet goes in on its own, why keep using new bits with superglue to extract the magnet, rather than just add a dab of glue to one you used before? Sure, you can end up with your extraction bit having multiple magnets stuck on the end, but far better than wasting several bits.

Why not just drill out the old magnets and replace them altogether? Sure maybe some of the bit holders have plenty of room for bits and multiple magnets but others can be somewhat shallow and need all the room they can get, especially for power bits that can wobble when they're not seated far enough in.

@@AnthonyLauder superglue/CA glue does not have a lot of resistant to shearing force. Doc should be able to easily twist the magnet off the bit.

Content like this is what I like most

Use a short demagnitized 1/4 bit with a flat end (e.g. non-security 5mm or 1/4 hex) in order to "extend" the extisting magnetic field beyond the walls of the bit holder. Then use this setup to determine polarity of new magnet.

What if you really need to replace a magnet vs. simply add a new one (because of depth limitations)? Have you looked into how to remove an existing magnet?

A trick, use a smaller magnet when checking polarity, easier to pop out.

Or just leave it in there. It’s probably not sticking to your bit more than another magnet.

I'm confused. If you add a magnet and it doesn't come off with the bit, doesn't that mean you don't need the superglue? That mag ain't going anywhere. Just leave it in there.

Even the ones he glued on to take out acting like the bit and the magnet are now no good, just break the magnet off. Its superglue, on metal, not permabond. Itll break right off w pliers. Chuck the bit up ina vice, grab the magnet w pliers and twist.

Sent here by Gar's Tips & Tools

Aside from the other suggestions already posted for testing the polarity of the existing magnet inside of the tool (using the same bit with the glued on magnet, making two test bits - one of each polarity, using a shorter 1/4 hex bit/ extension bit to extend the magnetic field to the tip of the extension, etc) here are a few more methods to try: You could simply use a basic 3mm-6mm telescopic magnetic pickup tool if you have one (which is essentially what you're making by gluing those magnets onto the ends of those bits if they're oriented the right way). Or, if you don't have a magnetic pickup tool (or one with a small enough head to fit into the 1/4" slot), and you don't want to bother making a makeshift pickup tool by gluing a magnet onto the end of a bit or the end of a thin dowel or the end of a typical yellow HB pencil with its eraser and ferrule removed... You could simply place the magnet onto the center of a small piece of thin plastic film (doubled up plastic food wrap, a piece of a grocery bag or a ziplock bag or related) or a piece of slightly thicker plastic film of some kind (20 mil vapor barrier or related). Then wrap the magnet in the plastic making a sort of tear-drop shaped pouch or an upside down parachute that you can use to hold the end of to lower the magnet down into the slot then pull out again (the 4mm diameter magnets would make this easier/ allow you to use thicker plastic).

Why are people making this more difficult than it really is. Just take the glued on magnet off the bit and flip it around. Its super glue, not permabond. Pair or pliers or chuck it up ina vice and itll break right off.

Have two test pieces. One hex bit with a glued on north to south mag and a second bit with a south to north mag.

Thanks Doc, I had to do this a couple of months ago and it works great.

Great idea Doc 💡 👍

Would it be best to first take out the old magnet?

Since you alread now have multiple bits with magnets glued to them, you can just use one of those to check the polarity needed, no need to loose more magnets that you need to glue to new bits :)

@@jacksmith2315 never said it's permanent, but when you first have a magnet on a stick, then it's much easier to use that to test if the magnet is rejected or attracted to the one inside, and thus much faster to know the polarity on the one you want to glue inside there. What whatever fits you.

If you can’t get the magnet out after accidentally dropping it in, isn’t that “mission accomplished”?

If you create a "test bit" that is an old bit cut so both ends are flat. Then prior to testing mark one side of the magnet with a sharpie, you put the magnet on one end of the test bit and using the bit turn it over and see if it is attracted or repels the internal magnet. If it repels then the facing end of the magnet is your glue side. And visa versa.

Great idea! I don’t see why not.

What make is the bit holder at 2:24 which looks like the key for a drill chuck?

The bits that have the magnet glued to them, put them in a vice, grab the magnet w pliers and twist, will break the magnet right off. Also, if the magnet stays in the bit holder, thats what you want, just leave it in there. Will still hold the bit in the bit holder just fine. Idk why made this so much more complicated

👍

I think you should invest in some CA Glue .... It is like crazy glue but it actually works on just about any type of material .. Crazy glue is garbage which i would think you know cause it looks like you are using Gorilla glue...BUT CA Glue is soooo much stickier and dries super fast and you do not need as much as you were putting on the magnets. Just my 2 cents ...give it a shot !

Have you ever looked at the egamaster range of tools? About the most expensive specialist hand tools you can buy.

This ain't a bad idea at all.
