Some of this has been covered, but here goes anyhow.

Stick with the 1/8" drill.  It is slightly smaller than the rivet shank
and
so you will not run the risk of enlarging the hole.  Drill through the
factory head of the rivet only.  Use the shank of another drill or a 1/8"
punch to pop the head off then punch the shank out the back.  Supporting
the
material makes this easier sometimes.

Use what's called a "split point" bit.  It will not walk around like a
regular one.  Spin the drill one or 2 revolutions by hand to start it.  No
punching necessary.  If this does not work, get a rivet removal jig.
(Doesn't work for flush rivets.)

The real reason to use a #30 bit for new holes is that it's nearly
impossible
to ram a 0.125 rivit into a 0.125 hole.  Zero clearance and all that.  And
the shank swells when you drive the rivet.
