Or you can drill a template with plywood ... an then reuse for the tank...

The pro would be suction cup. I don’t know how I feel about cheap bits though.

$30 for the guide and 15 piece set of diamond hole saws? Good lord where are the cost savings... "Never Rust Carbon Steel" may be the first place, "High Quality Diamon" is the other

I like the kit I got at Home Depot in the tile aisle. It came with double sided adhesive and you adhere the guide to the glass and it provides a reservoir for water while cutting.

Does the one you linked have a way to hold water? Do you not need water for this? I thought it was necessary to keep the bit cool

The price and quantity of bits included seems surprisingly low.

Is there such thing as a quality diamond bit? I was under the impression you can drill a couple holes then need to trash the bit because the diamond coating wears out? I used a cheapo for a two hole project then tossed it.

for the same cost of this HDX one saw and kit, i'd rather get that amazon guide.

There’s such a thing as a bad epoxy. Those thing wont last cause cheap glue.

Diamond dust is cheap.

If you want any life out of your bit you're going to want water to keep it cool.

A ring of plumbers putty did the trick for me

I taped the garden hose to the tank next to the drilling spots... Plumbers putty seems like a better way.

Plywood, plastic really anything so the hole saw doesn’t “walk”. The bit in the middle is usually longer than the hole saw, so whatever you use for the template just make it’s depth is greater than that bit. Just clamp it on the tank.

I do a fair amount of woodworking and more times than not it’s all in the “jig” you buikd
Or buy to get consistent repeatable results.

... also what shortens the life of diamond hole saws is running them at high rpm with no cooling.

Go slow. ESP just before it breaks through.
Very light pressure and let the blade do the cutting.

Lots of cooking.

make sure you tape up the other side, so glass wont fall when the cutting is done. or you can just place a towel at the bottom, that will catch the glass.

Clamp a piece of piece wood to the bottom side so that it helps to prevent you pushing through with too much force and adding chips at the end.
