Diamond HOLE saws at Princess Auto
 

Just looking through their sale catalog, 5 pc diamond hole saw kit 3/4-1 5/8" ($29.99)

Need to measure those 1" bulkheads for the drill size.

I believe the 1" take 1-3/4

I looked at Princess Auto on the south side the other day. They didn't have any. That really sucks if they do now as I ordered some form China.

Last time I was in princess about diamond hole saws the clerk just stared at me. So grab'em , cheaper than EBay

sale starts July 15.

need to get there early as place fills up with farmers in no time.

I wouldn't waist your money, you're basically spending $30 on one hole saw as the only one you'll ever use is the 1 5/8" (42mm). I've drilled many, many holes the smallest one Ive ever used is 42mm and that was rare, 45mm is the standard for most 3/4" and some 1" bulkheads.

Rather buy exactly what you need from TKH Diamond Tools
Best deal I've ever found, and I can vouch for them, they work well.

Ebay... I bought a 65mm hole saw for a 2" bulkhead and landed on my doorstep about $25 for everything. If you want I can look up the name of the seller .. it was from Hong Kong, but really, seriously, it was like $15 for the bit and $10 for the postage.

And if ebay not really your thing, I believe mops.ca (based in Ontario) sells diamond hole saws in the $20-30 range.

You need a 1-3/4" hole for a 1" bulkhead. And that's assuming a sched40 bulkhead (black). Sched80 (grey I think?) is even thicker walled and will require a larger hole size for 1".

Oops. Well, I don't need to look up the name of the ebay vendor I used .. it's the same one spshelps has linked to. So basically I can vouch for that vendor as well.

I have used those vendors as well ...holesaws work just as well as the 50.00 ones

That's who I just bought mine from...

I bought them Monday and haven't heard a thing from them yet though.

like I did point out, wasn't sure of the bit size required.

Whats wrong with the ones from MOPS.ca ?
$14 for a 45mm with $6 for shipping http://www.mops.ca/cgi-bin/SoftCart....ss5122ff26fd26

I got mine from mops.ca. Worked well for me.
