Hi. I ordered mine from Ebay just the other day. For a one inch bulk head on the Jl aquatics site it said you need a 1 3/4inch hole, which = 45mm so on ebay i googles diamond drill 45mm and lots came up. If you scroll down theirs a set for $12, it comes with 2 different sizes, a 45mm (perfect for one inch) and 38mm and 28mm, with shipping it came to $20 Canadian with shipping, and it came within a few days, they worked great, its called thk Diamond tools, just thought id mention it, ps when calling stored some placed call them whole saws and some people call them drill bits, seemed to make a big difference depending who i called
