thanks in advance

Depends on the diam of the hole, if its for buttons, these are good for any material.

i suggest you to put a piece of wood under and make sure that the plexi you are drilling is not moving anywhere...i experienced that if you drill slowly you may crack them...also at the fast speeds the plexi becomes hot and makes it easier to drill and lowers the possibility to have crack...good luck...this is what i experienced...

Keep in mind that plexi tends to ball up around the edges when you drill as the plastic melts and cools.

You should put down masking tape on both sides then cut to keep scratches at a minimum too.
