It really was that simple.. honestly. If you happen to have a piece of glass your not using then practice on it first so you get a feel for it. Like an old tank lit or something like that. You may even be able to get Lowes or Home Depot to give you a scrap piece for just a couple bucks. I had an old lid in my garage so I hit it first and once I seen how easy it was I just laughed at myself for being so nervous. Just keep a good water flow on the bit and go slow and steady. Don't push the drill, just let gravity do the work. The hardest part for me was just making sure that the glass wasn't tempered beforehand. Once I knew it wasn't it was smooth sailing.was it really that easy??? ive watched a tone of how to vids, also have brought the diamond drill bits. but still nervous as hell about attempting it lol
