If you can't slow it enough, can you spray-cool when drilling plastic?
I forget if you'd want wood bit or metal bit for this ?

If this particular acrylic machines at all like Lucite™ (only acrylic
i've machined, in a prior century!), it also wants to be machined with
its protective adhesiver-paper cover still on, it helps prevents
chipping.  If you don't have a cover layer, shelf-paper or
packing-tape might temporarily replace it ?
