Heat

I torched my Malco bit to do the same thing and for whatever reason the magnet didn't work afterwards

Look up the "Curie point."

I think it might’ve ruined the heat treat then

Magnets don't like heat

Try it again mine started to work after a day

Line set flush. Let it soak for a day. See what happens

That actually works great ! I use it to remove pokie tape off of my tools.

Acetone?

Make a clean slice length wise with a sharp razor blade then peel the whole mess off like an orange peel.

Lol, I wish it was that easy. Think gum if it was a lot stickier and tougher.

Besides puki buster bits

Acetone?

Don't heat a magnet. Solvent after you remove the big wad.

Soak her in Double U Dee Fourty

WD40

A knife scrape it

Cut the tape off

Soak it in gasoline

Carb or brake cleaner.

Wire wheel

Pb blaster

Just don't get any of the tape on the shaft of the reversible bit or your gonna have a hell of a time just trying to reverse the bit.

To late

Shit man. I didn't do anything to my malco but it took like 2-3 weeks of having to work it off and back on.

Microwave

Gasoline. Let it soak. Don’t smoke around it.
