Best Drill Bits For Glass – 2020 Ultimate Review

Glass is one of the most difficult materials to work with as it's fragile and more likely to shatter due to carelessness and negligence, or in some cases, the lack of the right tools. Fortunately, there are drill bits designed specifically for glass, and using those results in little or no cracks. 

This essentially means that you cannot use 'any' drill bit on the market when you are working with glass. Doing this increases the danger of the glass breaking. For this reason, there are specific drill bits that work better and without the glass shattering.

Moreover, the key to drilling glass is to use a material harder and stronger than the glass itself. If any drill bit is used, it won't do the job properly as compared to doing it with a drill bit designed specifically for glass.

How to Drill Glass

Drilling holes in hard and brittle stuff takes talent and skill. Using the wrong technique or tools can waste materials, time, and energy, and may lead to injuries. Fortunately, talent and skill can be acquired. Follow these tips and steps to make the most out of your drilling sessions.

  1. Acquire a carbide bit designed especially for tile and glass.
  2. Since glass is incredibly hard and smooth, the drill bit will start to wander once you begin drilling. To give a foothold to the bit, try taping a small piece of dense cardboard to the glass. This should be done at the place where you want to drill.
  3. Begin at a slow speed so that a dimple is created in the glass.
  4. After making the dimple, remove the piece of cardboard as you won't need it now and continue drilling at a higher speed than before. Make sure not to drill too hard or fast.
  5. Pour some water on the area you are drilling to lubricate the surface and make it easier to drill.
  6. Make sure to run the bit under running water to cool it off. Otherwise, overheating may cause the tips to get burned.
