size bit for bulkhead??

I have a quick question guys. What size bit do I use to drill for a 1 1/2 bulkhead and a 2 inch bulkhead? Is it a 40mm and a 60mm?

1-1/2" bulkhead usually needs 2-3/8 (60mm) hole
2" bulkhead usually needs 3" (76mm) hole

It depends on the brand of bulkhead. You need to find the manufacturers recomendations as they are all different.
