ParticipantI recently bought a couple of adjustable bits and a 2-jaw brace. My first time trying it, and the larger bit is stuck. I can’t seem to free it even after removing the chuck from the brace. It’s almost like the shank fused onto the jaws.
Any suggestions? I think the bit might have been too big.

ParticipantTry some WD40 or other penetrating oil and let it work for a few minutes. If the bit is still stuck in the jaws grab it in your vice and try some hammer blows on the back side (the one in the third picture).
Be sensible with the hammer!
The idea is to remove the jaw cover and get access to the actual jaws in order to separate them from the bit.
Hopefully it will work.

ParticipantIf the collar is loose , reach inside with a screwdriver and tap gently on the ends of the inner jaws this should break it loose.

ParticipantIn one picture it looks like the flats of the bit are not on the chuck flats. You may need to rotate the bit to align them to open up the clearance.

ParticipantSometimes old brace-chucks and square-tapered bits from different manufacturers don’t mate well. Often it will work loose in use; more annoyingly as in your instance it jams tight.
Very often in cases like this where two dissimilar metals are melded together, an easy first approach is heat. It’s worth trying as a first approach.
I’m not advocating blasting the day-lights out of it with a blow-torch, simply the sort of heat that a moderate oven in your kitchen can provide…. say about 150 degrees for 20 minutes, possibly followed by a quick douche in cold water.
Both metals will expand/contract at different rates and will usually disengage after a smart clout with a wooden mallet.
If this doesn’t work…. go to stage 2…………… whatever that ma
