Granted: Drill bits can work. However, they are inclined planes. Read, wedges. You force them into the material and as they turn they try to spread the material out as they cut.
A much better way to go: Check with shops that supply machinists tools and buy an End Mill of the appropriate size you can chuck into your drill.
End mills do not wedge. They have cutting surfaces across the entire end as well as sides. While they are more expensive, with proper care taken they will cut clean holes in even the most brittle plastics.
