I use this set from Drilax. I think anything smaller would be useless for drainage. I borrow my boyfriend's drill. Watch YouTube videos on how to do it, but essentially you want to squirt some water at the drill site, having it wet constantly so it doesn't overheat. You don't need to put all your weight on it, but you will need at least a little pressure. What helps me is putting pressure only on one side of the bit (it's a miniscule slight angle) whenever drilling, and switching/rocking occasionally from different sides. It really helps deepen the cuts. This also helps when you're starting to drill (keeping it on an edge rather than directly flat down), otherwise your bit will bounce all around the bottom of the pot (you'll still need your other hand to steady the drill for the beginning cut... Maybe even your feet to stabilize the pot, lol).
I know when I'm about to break through, because the water I squirted onto the pot will suddenly run through. And because I'm drilling at a very slight angle, I only have a semicircle hole, and I just have to rotate my pressure on the other side now. It's a rather gentle finish and I've never broken a pot!
I hope some of that made sense. Sorry for the wall of text. Good luck! It's super fun!
I use this set of drill bits I saw suggested on this subreddit. I have used them for several pots with no issues or breaks so far. https://www.amazon.com/dp/B00DRRDFXC

Depending on the size hole you want to cut, get this type: https://www.amazon.com/Diamond-Hole-Drill-Granite-Glass/dp/B00DRRDFXC/ref=pd_lpo_469_bs_lp_img_2?ie=UTF8&psc=1&refRID=GEGR9BY5JSS4KGAVHABX
Most glass cutting bits will be diamond coated, and they aren't expensive. I got a 1/2 inch size bit for cutting holes in bottles, and the type I linked handled that far better than the normal style bits (also diamond coated) without cracking or chipping the glass.
The important thing is to take it slow, and don't press too hard on the glass, let the bit do all the work, and have it supported underneath to avoid cracking and chipping.
