Drilling a hole for a bulkhead fitting in acrylic is pretty straightforward, but drilling glass is a little trickier. It can be done by anyone with patience as long as you follow our easy steps. Drilling tanks is an easy way to make some extra cash by drilling tanks for friends. To save $$$ a club could purchase a hole saw for its members. You will need a diamond tipped hole saw, drill, drill ring or modeling clay, sandpaper and saw lubricant.

Make sure the glass you will be drilling is NOT tempered. Tempered glass will shatter on contact.
Figure out where you need the hole and mark with a magic marker.
Using the drill ring or modeling clay, make a small dam about 1" bigger than the hole to be cut, about 1/4" high.
Drill. The easiest way to do this is using a variable speed rechargeable drill. This way, you can start slow and then speed up. Start slowly, allowing the hole saw to scribe the hole that you want without walking all over the glass. Drill slowly like this until the scribe is about 1/16" deep.
Put a few ounces of the lubricant into the ring or the well that you made with the putty. You can now speed up on the drill. DO NOT apply a lot of pressure. Let the saw do the cutting. Rock the drill slightly so the drill does not bind while it cuts. Keep the saw wet. When the saw starts to break through the opposite side, back off the pressure and let the saw cut through. Place a piece of cardboard or a towel under the hole so the cut glass does not drop onto the other side glass. When through drilling, use a small piece of sandpaper to dress the hole to avoid stress cracks. Wash the tank out to remove the lubricant. Remember the saw "dust" you see is actually ground glass.

LIMITED USE HOLE SAWS The hole saws above, under optimum conditions, should be able to drill 100-150 holes before wearing out. The limited use saws below are made to produce 4-6 holes. Perfect when you aren't going to need a lot of holes.

Instead of having to fool around with putty or clay, simply use this 3" drill ring.

Use this handy Suction Base Ring for drilling glass whenever you use coolant. Made of a special rubber compound Dual Durometer rubber which is harder up top to retain its shape, and very soft on the bottom for the suction lip to create a vacuum. A nice feature of this drill ring is it won't break the glass if dropped on it accidentally because of the material it is made from. Easy to use: just wet the base with coolant or glass cleaner and press onto the glass. Fill with coolant and start drilling.
