Hi, I have a diamond glass drill for 3/4 " bulkheads and it is for glass, well it also works fantastic on drilling a bulkhead hole on my acrylic sump. I did not get any burn or stuck plastic to bit and the hole itself was quite clean. In the past I used those cheap hole saws and they were never great and always had to clean the hole from melted plastic. Learned something new today.
