Ahhh... forgot this little list:
Diamond Hole Saw size 60mm = 1.5 inch Bulkhead
Diamond Hole Saw size 45mm = 1.0 inch Bulkhead
Diamond Hole Saw size 38mm = 0.75 inch Bulkhead

Those listed are for standard sized bulkheads. There are some fancy heavy duty bulkheads that require a larger-sized hole in the glass tank. I am not sure the size Diamond Hole Saw required for those.
Use this conversion to determine what size you need. 25.4mm=1inch
MarineDepot lists a size 1 3/4 " hole for a size 1" Bulkhead. High School math will get you 1.75 x 25.4 = 44.45 That is the size in mm diamond hole saw that you need.
I hope that was easy to follow???
