Drill Bits

[Jzhou]

What are your opinions on tungsted drill bits for cutting glass. Some of my larger bits are somewhat worn and I saw some at home depot for cutting ceramic. The guy said it could also be used to cut glass. Does anyone have any experience with them?

I've had good luck with the diamond hole bits sold on EBAY, they give you a circle. what size you need?

 

[Jzhou]

I normally get mine from ebay to, but since I saw some bits at home depot, Just wanted some insight on them.

 

[Alex]

Are you referring to the single bits or whole bits.

 

[Jzhou]

Whole.

 

[Alex]

no experience with these but i'd recommend you try it on a scrap.

I bought my set from glass hole.com but they are a little expensive. +1 on trying on scrap first

Don't forget to use enough water to keep the bit & glass cool and make sure you're no trying to drill through tempered glass.

What the best way to be 100% the glass is not tempered glass?

 

[Jzhou]

Tanks that are tempered normally have a label on the bottom that tells you to not cut or drill.

Not always. To be sure try to contact the manufacturer.

The tempered label can also be in a corner of the tank. You can also tell by the sound of the glass when you tap it with your fingers.
