I suspect it would depend on type of material, type of paint,
condition of both, etc. but have always assumed applying some kind
of tape--electrical, masking, etc.--over and under--if the
underneath is painted, too--the area to be drilled is about all you
can do to prevent chipping. Make sure you use a sharp bit, and a
variable speed drill so you can start slow to drill through the
paint.<br>
<br>
Begs the question: do you use a punch to 'prime' the hole--with or
without tape--before drilling?<br>
