what s the right speed for drilling 1/2" acrylic? I need to drill a couple for my filter outputs. Also, what kind of bit, holesaw, boar, or spade bit?

I've used a hole saw (slowly----very slowly) and cooled it with water.

If you can- Start at the top and finish it from the inside. This will prevent it from splintering when it pops through.

I agree with rallysman, drill with a holesaw very very slowly and make sure the bit isn't blunt. To stop splitting or chipping I clamp a piece of wood on the opposite side to the drilling.

Slow speed and sharp bit. That clamping a pice of thin wood on the exit size works great!
