Production tool supply has a sale on Black&Decker Bi-metal hole saw's with shank. I bought them at one of there retail stores and they have a website www.pts-tools.com but they don't have them listed on the site, there phone# is 800-366-3600. The price on the 4 3/8" (112mm) is $13.90---4 1/2" is $16.40---3 3/8" (86mm) is $5.45, plus .70 for a 1/4" pilot drill for the hole saw. my local tool store wanted $37 for 4 3/8 and $25 for the 3 3/8.
I bought the 3 3/8 and the 4 3/8 to install 92 and 120mm fans. I auctually like to cut the hole a little smaller than what the fan size is cause it always turns out to be a little bigger.
I also see now they have a 12 piece black & decker set for $48.50 reg. $149.50 with the following hole saw's---4 1/2---4 3/8---4 1/4---4---3 7/8---3 3/4---3 5/8---3 3/8---3 1/8---2 3/4---2 5/8.
The part #for the 12 piece is is FZ51-SET2
These all come with a 3/8" shanks so they will fit in most drill's--some other brands of hole saw's come with a 1/2" shank and you need a 1/2" drill for those.
The website says free shipping.
