Easily. I've drilled loads of holes with a 1" auger in a historic B&D drill. You do need 2 speed gearbox for that - 10mm ought to manage without though. And you need reverse to get it out again, or some tough gloves.
When I was drilling a lot in oak I took to removing or shortening the
pointy threaded tip sometimes. It pulled the drill in too strongly and
the process was much easier going with the pressure reduced, but ymmv.
A cheap drill went up in flames (literally) on one occasion, but yes is
the answer, with care.
Depending on what you are trying to do, I've had good success with
Forstner Auger bits in std drills:
I think I used one to chain-drill a line across a sub-terrain wood
gate post with the bit in a long extension and think it was probably
tougher than the alternatives.

If you need to reduce the "pull" of the worm drive on a one off basis
(rather than permanently by grinding the worm off/down) pre drill a
small (say 4mm) hole with a normal bit first. That will leave the worm
with far less material to engage with.
