Thakns to all. I fixed it. I took the cover off and blew out
accumulated carbon crud. It made a little cloud, I tried not to
breathe and walked out of the garage for a little while to let it
settle.

After that, the drill runs (as it did before), but it no longer trips
the same GFCI breaker. I tried starting and stopping it many times,
shook it while running etc, but the breaker would not break. I made
some pictures, but I doubt anyone would be interested -- just brushes
touching the rotor.

I want to say big thanks to all people who gave me good suggestions!
It was the easiest fix of my life.

I also tested hot to ground with a multimeter, no obvious leaks (I did
not use a megger, but I used the 1M setting of the multimeter).

For the record, I used rubber boots and gloves while I was trying the
drill.

Indeed, there is a big threaded hole on top of the drill, for
inserting a big handle. Maybe it is even meant to be held by 2
people with a big handle.

The problem was the carbon dust, since its conductive.

I have to remember this!!!!

Yep sure is. Commonly known in Australia as a
"belly buster". Get the bit jammed some time when
you're using it and you'll find out why!
