If this is Perspex/Plexiglas, I've had great results with a good sharp
Forstner bit in my drill press at medium (say 750 RPM) speed and a
not-too aggressive feed.. No melting, just lots of crumbly shavings.
I've done this with sizes down to about 1/4", but no smaller. When
you're almost through the material, turn it over and complete the hole
from the back side. Very clean edges, with no chips at all.
