For a 1" bulkhead you need a hole 1-3/4" to 2-1/4". I use a 2" hole saw for mine.

thnx jayray I have a 1 3/4"!!

[thejuggernaut]

it depends on the bulkhead. Do you have the smaller black plastic ones or the gray SCH 80 Hayward bulkheads

Another tip, I find that a electric drill is more suited for drilling glass. They do not have as much torque in comparison to a cordless in my experience.

Is there a certain type of drillbit to use for acrylic?

I use 1 5/8" or 1 3/4" or 45 mm

A standard wood hole saw bit will work great
