Drilling tanks is easy. Just need a cordless drill, or one with good speed regulation, and a diamond hole saw. Start SLOW speed, using your hand to hold the bit steady, but at a slight angle untill it starts its groove. Then slowly tilt the drill perpenbdicular. Dont push on the drill, let the weight of it do the work. Ohh, water fro bit cooling too.
There are some great how to vids on youtube on drilling glass.
