Yes, you can drill the plastics with a standard bit, but the pointier bits cut nicer and reduce the likelihood of cracking in plexiglass.

Question; Would not starting your hole with the smallest drill bit you have and working your way up to the hole size you want by redrilling with with the next size bit up also lessen the chance of cracking the Plexiglass ?
