Trick to drilling a larger hole without damaging wiring

[jawdoc <drbrooks@xxxxxxxxx>]

I want to replace a recessed sensor that someone prior placed a non
metal contact in a metal door.
I need to drill out the hole bigger.  But I don't want to bugger up
the wire drilling.
Is there a special drill or a trick to do this?
I am scared in this particular door to push the wire up that I will
not be able to retrieve it.
Thanks in advance!
