How to Drill Through Glass
- 1). Place the Styrofoam block in the bottom of the container and place the glass on the Styrofoam. The purpose of the Styrofoam block is to prevent the drill from punching through the container once it has gone completely through the glass.
- 2). Fill the container with just enough water to cover both the Styrofoam and the glass. The water acts as both a lubricant and a coolant. This greatly reduces the risk of the glass chipping or breaking during the drilling process.
- 3). Place the diamond bit into your drill press or power drill.
- 4). Place the tip of the drill bit on the glass and drill in bursts, using only slight pressure against the glass. If your drill is capable of variable RPM (rotations per minute) settings, it is best to start at a lower RPM. Too much pressure or too high of a RPM speed will shorten the life of the bit, and create excess friction and excess heat. These will all greatly increase the chances of breaking the glass.
- 5). Drill in short bursts until you drill completely through the glass. Once you have finished drilling, remove the glass from the container and dry it off. Use care when drying it in the event that any jagged edges remain.
