Tools and Materials Needed

The main tool you will need is a rotary tool, such as a Dremel. You will also need diamond drill bits specially designed for drilling into glass.

The size of the drill bit will depend on the size of the hole you want to drill. I like to have a few sizes in my toolkit to match different projects.

You will also need a shallow dish filled with water to keep the drill bit and glass cool during the drilling process. You should wear safety goggles and a mask to help protect yourself from dust and glass particles when you are drilling.

I also like to use a piece of wood as a platform to rest my sea glass when I’m drilling.

How to Drill Holes in Sea Glass: Step-by-Step Guide

Once you have got things ready, it’s time to start drilling. Follow my step-by-step instructions below to successfully drill holes in sea glass. And don’t worry, like most things in life, practice makes perfect. So if you do break a couple of drill bits in the beginning, it’s perfectly normal.

  1. Step 1: Prepare your work area by placing a shallow dish filled with water on a stable surface. This will help keep the glass and drill bit cool during the drilling process.
  2. Step 2: Put on your safety goggles and mask to protect your eyes and lungs.

  4. Step 4: Choose the appropriate size diamond drill bit.
  5. Step 5: Hold the drill tip under the water so that it is touching the piece of sea glass.
  6. Step 6: Hold the drill at a slight angle and start drilling at a slow speed. Let the drill bit do the work and avoid forcing it through the glass.
  7. Step 7: As the drill bit starts to etch the surface of the seaglass, slowly raise the drill to decrease the angle of it.
  8. Step 8: Now slowly rotate the drill and move it in a circular direction. I like to rotate it clockwise and then anti-clockwise. There is no set rule here, but you are allowing water to flow into the hole. This helps to cool down the glass and prevent cracks or fractures.
  9. Step 9: As you get further through the glass, make the rotations smaller and smaller. If you are working with a bigger piece of sea glass, take breaks if needed to prevent overheating and allow the glass to cool down.
  10. Step 10: Once a clear hole starts to form and you can see the glass dust from the drilling under the water, hold the drill straight and continue.
  11. Step 11: You’ll know you have been successful when you feel the piece of sea glass “snag” or “bite” as you complete the hole.

Remember to work slowly, be patient, and take your time, learning the right technique will help you drill your sea glass with ease.

Common Mistakes to Avoid: Tips for Success:
  • Rushing, which can lead to cracking or shattering of the glass or breaking your drill bit.
  • Not using proper safety gear.
  • Applying excessive pressure.
  • Not using enough water to cool the drill bit and glass.
  • Start with small drill bits and gradually increase the size to minimize the risk of cracking.
  • Wear safety goggles and a mask to protect yourself from glass shards.
  • Use a gentle, steady pressure to avoid breaking the glass.
  • Keep the drill bit and glass wet throughout.

By following these tips, you’ll be able to safely and successfully drill holes in sea glass.
