Source for inexpensive glass hole saws.
Hi Tech Glazing
#210 13060 80th Ave Surrey, BC (604) 501-1212 About 4 years ago I bought a hole saw from these guys and got about a half pound of cutting compound (grit) the hole saw is 1 1/4in and worked great. I've drilled probably 30 holes with it and just found the company again today. They are getting out of the cheap ($25) saws but will order them in for people but you may have to pay a shipping charge. If a few people wanted to order them together you'd save that charge. The only downside to these is that you NEED a drill press and a bit of patience. To drill 1/4 inch glass took me about 5 minutes per hole but on a 10-15 gallon tank the holes took about 2 minutes. The saws wear out but mine still has about 3/4 left so like they said at the shop the saw should last about 100 holes give or take a few. Doug

My understanding though is the diamond chips are glued on so the bit only lasts a couple holes. Granted if you are just drilling your own aquarium that would do but if you are drilling a few here and there....
