Your tools are dull. Alternatively, try a heated needle for a small
hole, a piece of hot metal tubing for something larger. Most plastics
are more or less machinable so your technique needs refining.
Are you attempting this with a hand drill or a drill press? How large is the
drill bit and how have you secured the glasses? Are these the 10-for-$1.99
"beach combers" that kids love? Are you using an old drill bit that might've
lost its cutting edge or a new out-of-the-package bit?
When I did this, I used a 1/32" bit, locked the entire package down on top
of my drill press, wood block underneath, and dropped it down SLOWLY. It
took several minutes of tedious work but I was able to do it. I first tried
it with my hand drill and quickly decided a drill press was the better tool.
If you have a plastics shop (TAP comes to mind but I haven't seen one in
years) near you, they might also offer some tools for "punching" the holes.
Without knowing exactly how you are trying and exactly what
you want, it is difficult to offer suggestions.
How big of a hole? Are you drilling slow or fast RPM? Are
you using little or a lot of pressure? In what way does it not seem
to work? What tool are you using? Are you holding the object and
tool securely (like a clamped part while using a drill press?
Thank you all for fine suggestions. The glasses are $1 type until I
find the best way to put a 3/4" hole in center. Please don't ask me
what for...I will have to kill you ;) but will reveal the reason
I'm inclined to try the heated points first then enlarge with tubing
until the right size is met.\\
This means a lot to me and I am grateful for you input. You all may be
participating in a major discovery.
