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.
