Whether you're making shelves or assembling a table, there all types of projects that require drilling holes through glass. Working with glass might seem intimidating, but the task is not too difficult. All it takes a standard power drill, drill bits and the proper technique to get the job done. Here are simple steps for drilling into glass.
What you'll need:
Step 1: Select the correct drill bits.
Both diamond-shaped or tungsten carbide drill bits can effectively drill through glass. Make sure you plan to use a few bits. One should be the size of the hole while the others should be a size or two smaller.
Step 2: Carefully measure the location of the holes.
Measure the location of the hole and mark your spot with the black marker. Avoid drilling within three-quarters of an inch from the edge of the glass.
Step 3: Place the glass on top of a cushioned surface.
Set the glass on top of corkboard or a rubber pad. Make sure this protective surface is on top of a flat tabletop or workbench.
Step 4: Spray the glass with water.
Before you begin drilling, make sure the glass is coated with water. Keeping the glass wet throughout the project helps limit stray pieces of drill bits and glass particles from flying up while you're drilling.
Step 5: Put on safety gear.
Before you start drilling, put on your safety glasses, gloves and dust mask. This gear should help keep glass particles away from your eyes, hands or mouth while you drill.
Step 6: Start drilling a pilot hole.
Use one of the small drill bits to start drilling a pilot hole about halfway through the glass. Apply constant pressure and try to maintain a slow and steady drilling speed.
Step 7: Turn the glass over to finish drilling.
Drilling all the way through the glass at once can cause chipping on the backside. Flip the glass over and finish drilling through it on the other side. Once you've drilled all the way through the glass with a small bit, use the large drill bit to go through again. Make sure to drill at a low and steady speed to finish the hole.
