You can also use them to install hinges or handles on glass doors, or to create intricate patterns for decorative purposes.


  • Automotive Glass - The automotive industry uses glass drilling machines primarily for mounting attachments and sensors to mirrors. You will also see them being used to attach wiper mechanisms to the windshield or attaching sunroofs to the vehicle body.


  • Electronics - Electronics manufacturers often need to drill highly precise holes into glass components such as touchscreens or to install camera lenses and light sensors.


  • Decorative Glass - Fabricators who work with glass art and custom glassware will often use a glass drilling machine to create intricate patterns or to install hardware that holds multiple glass pieces together. The ability to drill small and precise holes into custom glass pieces can open up a whole world of creative opportunities for glass workers.


Types of Glass Drilling Machines

There are several different types of glass drilling machines available on the market and each one is tailored toward specific applications and production needs. Recent innovations, such as CNC drilling machines, have even made it possible to automate complex drilling patterns that were previously unattainable.


Let’s take a look at some of the different machines that are currently available on today’s market:


  • Vertical glass drilling machines have upper and lower drilling bits that drill vertically into glass sheets that are laid on a horizontal surface. These are commonly used when it is necessary to drill from the edge of the glass.


  • Horizontal glass drilling machines are used to drill horizontally into glass sheets. They are most commonly used for heavy duty industrial purposes like creating glass doors or facades.


  • CNC glass drilling machines utilize computer software to automate the drilling process with high precision. They are most useful in applications that involve a high level mass production and mass customization.

Choosing a glass drilling machine

Each type of glass drilling machine offers distinct advantages. When you’re choosing between the different products, you’ll want to evaluate each one based the following factors:
