Drilling tiny holes in plexiglass. Any pointers?
« on: January 11, 2013, 03:39:23 AM »
I am trying to make a jig which requires me to drill a bunch of tiny holes (.009"/.25mm) in a piece of plexiglass. I am using a modified Proxxon drill press stand/compound table with a Foredom motor tool to give me the slow speed and control needed for this operation. So far it has resulted in me breaking two drill bits!  >:( I am drilling at low speed and backing out the bit frequently but still no success.

Does anyone have any pointers on how I can do this successfully?

Thanks in advance, Chuck.

As I mentioned on the other Forum, use a lubricant to keep the plastic
from becoming sticky. Keep in mind too that a drill is only efficient to 3-4
times it's diameter, if I remember correctly.
