Glass cutting bit

i know its over your 1 1/2 inch request but i have a 48mm one you can borrow? its for installing a 1” BULKHEAD SCHEDULE 80
 
Whats the difference between these?

45mm Glass Drill bit works with our 1" ABS Bulkheads.

48mm Glass Drill bit works with our 1" heavy duty SCH 80 Bulkheads.

I got a 45mm and now I'm wondering if the Bulkhead I have will fit it.
