Glass Drilling

I think you need to get a battery or a new bit, it took me 2 or 3 minutes to drill each hole my 75 gallon tank.

 

this was using a diamond dremel bit in a cordless screwdriver, couldnt find a diamond hole saw at home depot

 

Oh, okay that makes sense. I got my bits off of ebay and they were pretty cheap too.

 

Thanks for the advise and re-assurance everyone. My plan at the moment is to just go ahead and do this cheap DIY overflow I found in the stickies. I just dont have the money to break this tank. I will end up drilling a tank for refugium purposes under the tank later though. I thought it would be fun to make stuff out of pvc anyways.

 

here are the minimum requirements in regards to distance for drilling glass

x = 1.5 t
y = 4 t
t = glass thickness

measurements are taken from the outer most edge of the hole closest to the edge of the glass.

single hole along side: x from edge

single hole near corner: x from first edge, y from second edge

holes next to each other: x from edge, 4t apart

holes next to each other next to edge: x from first edge, 4t apart, y from second edge
