Important Tips to know before Drilling the Glass

5. How to Drill Through Glass

Place the point of the drill at the center of the marked point on the glass. Turn the drill to the lowest speed and apply only light pressure. If you push down too hard, you could crack the glass. The process takes some practice, so you may want to try it on some scrap glass first. If you have a full sheet, check the corners for a small stamp that indicates that the glass is tempered. When you look closely, you can see small imperfections in tempered glass.
