LF 4" diamond glass holesaw. Calgary
 

I am looking for a 4" diamond holesaw to make a hole in a sump part for a filter sock. anyone have one I can buy/borrow?

I see new ones for $50-$60 but I only forsee ever using it for 1 hole.
Other options could be use acrylic(but bonds poor to glass with silicone) or have a go with the waterjet table at work but it etches the glass and makes it real hard to clean algae off of it.

what are you using a 4" hole saw for?

Have you tried any local glass shops?
Without a tripod your going to have a really hard time trying to drill through. I just drilled one of my tanks with my dad and we used a toothless bit and silicone carbide with diamond dust in it. Might work out cheaper if u can just find a glass shop to do it for you.https://uploads.tapatalk-cdn.com/201...89972ac696.jpghttps://uploads.tapatalk-cdn.com/201...f4d7fed547.jpghttps://uploads.tapatalk-cdn.com/201...a8c8003319.jpg

Glass is very easy to drill actually if you keep it cool, slight trickle of water. But yeah what aree you using a 4" hole for? That's a pretty large hole to drill.

Cut my glass
 

The 4" hole is for a filter sock..... I don't feel there is an issue with it being difficult or not its just a matter of finding a holesaw.

clamping a piece of plywood with the same size hole as your a cutting to the glass as a jig is the easiest way not to skip off your mark and scratch up your glass. ive also seen the diamond jigsaw blades. maybe drill a bunch of holes and cut out whats left after.

I have called a few glass shops and they all have retarded answers and finally admit they don't even have that size and don't have anyone skilled enough to cut it with a scribe wheel. Glass experts my ass More like order and markup experts

Tried asking Concept if they'll do it?

yup they said the glass would have to be 1" thick and they don't have that size saw. Companies don't want to help you out and cut a hole for $20 they want to sell you a huge aquarium for $5000

Why not just go with acrylic?

You can get around the bonding problem by creating a ledge for the acrylic to sit on.

A few small pieces of glass siliconed in place around the space.

Then you can put the acrylic piece in and just use silicone to seal it in.

That's the way my sump was build and hasn't been an issue.

I could go acrylic but im kinda OCD with stuff and would like glass. Heck if i could afford i would build everything from stainless steel.
