Default Drilling in glass

How would one make a whole in glass, such as a jar? I would think a drill bit would shatter the glass. Would a small grinding bit on the end or an air tool or dremel work?

I believe you can get bits for drilling glass. I don't know if the grinding bit would work.

Your best bet would be a Diamond or Carbide burr used in Dremel or anything with a high RPM (30,000 and up).

I just saw those at a tool store near me, I never even thought about how to drill glass until I saw them a couple days ago.

I've actually done it with a sandblaster before. Not sure if its the best way but it does work. I guess it depends on how accurate you have to be and how clean you want the hole.

Yep and I would use a slow feed into it.

There are special spear-point bits for drilling into glass. Use a lubricant such as WD-40 or Antifreeze while drilling.

Thanks guys. I bought a smaller test bit at Home depot. .125 inches. I put it on my dremel and spun it up to max speed and it drilled fairly easy (not putting any weight on it). I kept spraying WD40 along the way. I'm going to go get the bigger bit that I need now. I'll also post pics when I get a chance.
