...And adding my $0.15, don't blast your way thru a large hole in
a single shot. For even a 1/4 inch hole, especially in plastic,
start with an 1/8 inch drill. Drilling in steps becomes very important as the
size of the hole gets larger. A 1/2 inch drill has a lot of momentum and
messy things happen.
