Heat.

I once had to replace a 1/2" chain plate bolt that was through the
stem of my sailboat. Wouldn't budge no way, no how even with a
sledge. Heating it with a propane torch freed it up. Heat your
little suckers red hot and they'll come out even if you have to char
the hole they are in slightly.
Alternatively, you might try sticking the mallet in a freezer for a
while.

Ditto. If in doubt, burn it out.

Years ago I built a woodworkers mallet from oak with some lead wool for mass.
Worked fine for years, cracked a glue joint some weeks ago.

So I'm gonna just drill some holes thru the head and insert a couple
screws/nuts to hold the head together better. Attempt a pilot hole
with a 1/16" bit going thru about 2" of oak, etc. Drill bit freezes,
slips in chuck, won't come out. I kinda doubt it's the lead wool thats
holding it.

Tried a second pilot hole with a 3/32" bit. Same thing.

I tried using pliers, vise, etc to extract frozen bits. Nothin' shakin'.
Eventually they break off.

I could jerry-rig something to drill around the embedded bits, but I'd
rather extract 'em.

Anybody know a good trick for such?

First, learn to drill. You can't just plunge through 2" of oak in one
big attack. You have to relieve the chips regularly.

I've never had a drill stuck so tight in wood that putting the drill
motor in reverse couldn't back it out. But if you do break it off, take
it to a machine shop and let them cut through the broken bit with a
carbide end mill.

If you don't care too much what it looks like, it might just be
easiest to pound the bits in a ways with a punch and work around them
(being careful not to break any more).

Heating sounds like a good idea, but if they're broken flush or below,
that might be tough given the size.

Might be able to heat up the bits, with the tip of a
soldering iron. Black char is a lot less adhesive than wood.

To add some clarity. When drilling deep holes, it's
necessary to keep the drill spinning, and pull the bit out,
frequently. In some cases, drilling as much as 1/4 inch of
new material requires that you pull the bit out, and get the
chips out of the "flutes" or grooves, in the bit.

I doubt many machine shops can end mill a 3/32 bit. Who
knows? Maybe.

Set fire to mallet, retrieve bits from resulting ashes?

Seriously, though... If they're broken flush with the mallet face, urgh.
You could chisel some wood out around them to expose enough end to get a
grip on, I suppose. Then heat them (as someone said), then tap the
exposed ends with a hammer a few times to try to loosen things up a bit
more, then get some pliers on the ends and try to twist them out.

I did. As much as practical.

Drill press had no reverse.

Turns out the damned thing is full of hardened epoxy. I didn't
realize it was that resistant to a small drill bit.
