In regards to my question, I do believe I was in error with the
3/32"
measurement. The holes will end up being between 1/8" & 1/4".
I am not sure at this time since I have not as yet received the case
and some of the components.

Over the years I have had many occasions to drill Lucite or similar
materials. No problem drilling small holes in the material (1/8"
to
1/4") when in my drill press where I can drill slowly. However,
when I
drill the material and it is free standing, I have much trouble
with
the drill bit "grabbing" the material and causing small fractures.
The bits I have been using are just the ordinary HSS. I have a
project coming up where I will be drilling many 3/32" holes in an
acrylic computer case. It appears that I will not be able to use
my
drill press. Any suggestions as to technique or drill bits?

Thanks.

If you have a grinder, you can regrind the point angle for drilling
plastics. I can't recall offhand what the angle is. You can easily
find that on Google, or ask at rec.crafts.metalworking

I would rather purchase the correct drill bit rather than play around
with one of my good drill bits. Thanks .....
