Does anyone have a good technique for redrilling, slightly larger, previous
holes from which old bungs have been removed.? Often when bungs are removed
the surrounding wood gets chipped.
To make a clean appearance the hole needs to enlarged to the next biggest
bung size. But an ordinary drill will usually just chip more wood from the
periphery of the hole. Any suggestions?

Resizing a bung hole was the last thing I wanted to do on my teak decks with
hundreds (maybe a thousand) of bungs.  In my case (a wooden boat) the
fasteners were bronze boat nails; so there was not going to be any
unscrewing going on.  If your fasteners are not some sort of steel, you can
do as I did which was to use a spot weld cutter (auto body repair shops are
familiar with them).  If a bung had popped out due to thinning teak (we are
talking a forty year old boat), I centered the pilot of the cutter on the
nail head and drilled down until the nail head had been cut away and a
sufficient overall depth had been achieved for the bung.  To refasten, I
used short stainless deck screws with square drive heads (guaranteed ability
to back out if ever the need arose) driven down at a slight angle alongside
the remaining shank of the boat nail.  Then the original sized bung cut with
a tapered plug cutter out of scrap teak went back in.  The weld cutter
always cut a nice clean hole.  Whatever you are using to cut the teak with
is clearly the wrong tool.
