A common method of making holes in glass is with the help of a drilling machine. The thought of drilling holes in something as fragile as a glass bottle can be intimidating, but knowing a few tricks can get you off the ground.
The first step is to get to know your drill. When drilling through brittle materials like glass, it is best to use a diamond bit because it is precise and sharp. The next step is to protect yourself from glass shards by wearing gloves and eye protection. Work in a well-ventilated area, preferably outside, such as a backyard or garage.
Some important safety points when drilling glass.
Practice on some old bottles before processing your desired creation.
Be safe — wear safety goggles to keep glass shards from flying around.
Be safe — if your bottle cracks or shatters during drilling, wear protective gloves to protect against glass shards.
Be patient — don’t force the drill. Let the tools do the work.
Take your time – just a reminder to be patient.
