Drilling out is likely to heat up anyway in a less controllable way. If
you
do drill out use a left hand drill bit (if unavailable from an
engineering
supplier then regrind a normal one with the other set/rake) and left
hand
action drill




Yep, left hand drill bit was the plan.

The final assault is the Dremmel and small .5mm disc to cut a slot. I
reatain these worn down discs precisely for this purpose. Undoubtably you
cut into the surrounding material but keep the orientations the same also
balanced and neat cut either side it does not necessarily look too out of
place. If it does look bad then cut a strip of craft-shop metalised film
around the mic and it can look totally in keeping.
