How to Drill Holes in Sea Glass – A Guide to Creating Stunning Jewelry

1. Choosing the Right Tools

Before starting any drilling work, choosing the right tools is important. The three tools you’ll need are a drill bit, a drill, and a clamp. The best drill bits for sea glass are diamond-tipped, as these are the only bits strong enough to cut through glass. A Dremel rotary tool is also great for precise and detailed drilling work. Make sure to choose a drill that can hold the diamond drill bit securely and a clamp to hold the glass in place while drilling securely.

2. Safety First

Glass can be dangerous to work with, so be sure always to wear safety glasses and gloves while drilling. A little water during the drilling process will also help keep the glass cool and prevent cracking or shattering.

3. Mark Your Spot

Before drilling, make sure to mark the spot where you want the hole to be. This will ensure that the hole is in the right place and that you achieve a clean and precise hole. Try using a permanent marker if you’re having trouble marking the glass.

4. Drilling

Once the glass is secured in the clamp, turn on the drill and slowly apply pressure. Start with a slower speed and gently move the drill around the marked spot to create a small guide hole.

Then gradually increase the speed until the drill bit starts to grind through the glass. Keep the drill at a right angle and apply firm yet gentle pressure with your fingers. 

Remember, it’s better to take your time and be careful rather than rushing the process and potentially shattering the glass.

5. Cooling the Glass

To prevent the glass from cracking or breaking, it’s important to keep it cool. Using a little water during the drilling process will help lubricate and cool the glass. Make sure not to use too much water, as this can cause the drill bit to slip out of place.

6. Finishing the Hole

Once the drill bit has reached the other side of the glass, slowly pull it out and inspect your work. If there are any jagged edges or burrs, use a piece of fine sandpaper to smooth them out.

7. Cleaning Up

When you’re finished drilling, make sure you clean up all of your tools and equipment. This will help extend your drill bit’s life and prevent any accidents or injuries in the future.

Following these simple tips will help you create perfect holes every time when drilling sea glass. With a little practice, you’ll be able to confidently tackle any project involving sea glass and make sure it looks great!

So why not take the plunge and start drilling now? You’ll be amazed at the beautiful pieces of jewelry you can create with your newfound skills!

5 Considerations Things When You Need to Drill Holes in Sea Glass

1. The Type of Sea Glass.

There are two types of sea glass- tumbled and frosted. The ocean has smoothed out tumbled glass over time, while frosted glass has a more matte finish. If you’re looking to drill holes in sea glass for jewelry, you’ll want to use tumbled glass as it’s less likely to crack.

2. The Size of The Hole.

The size of the hole you drill will depend on the type of jewelry you’re making. For example, if you’re making a pendant, you’ll want a smaller hole to attach the bail (the metal loop around the neck) securely. If you’re making earrings, you’ll want a slightly larger hole so that the ear wire can be inserted easily.

3. The Type of Drill Bit.

You’ll need to use a diamond drill bit to drill holes in sea glass. These bits are made specifically for drilling through hard materials like glass and ceramic. You can find diamond drill bits at most hardware stores or online.

4. The Type of Jewelry Finding.

When drilling holes in sea glass for jewelry, you’ll also need to decide what type of finding (or fastener) you want to use. The most common options are jump rings and eye pins. Jump rings are small metal loops that connect the sea glass to the bail or ear wire. Eye pins are straight pieces of metal with a loop at one end; they’re used to thread the sea glass onto a chain or cord to create a necklace or bracelet.

5. The Type of Adhesive.

If you’re going to be using jump rings or eye pins, you’ll need some sort of adhesive to keep them in place. Super glue works well for this purpose; just be sure to use a very small amount so that it doesn’t ooze out and ruin the look of your piece. 

Additionally, if you’re using a cord or chain for your jewelry, consider using jewelry glue to secure the ends. This will ensure that your piece lasts longer and looks great!

By following these five considerations when drilling holes in sea glass, you can create stunning jewelry pieces that all will surely admire. With a little patience and some practice, you’ll be able to turn your sea glass into beautiful works of art. So what are you waiting for? Get out there and start drilling!

Some Common Mistakes People Make When Trying to Drill Holes in Sea Glass

Sea glass is a beautiful material that is often used for crafts, jewelry, and home décor. However, drilling holes in sea glass can be tricky, and many people make common mistakes along the way. One common mistake is using the wrong drill bit. Sea glass is a delicate material and can shatter easily if the wrong bit is used. 

Another mistake is drilling too quickly. It’s important to take your time and drill slowly to avoid damaging the sea glass. Additionally, not using enough water to lubricate and cool the drill bit can cause the glass to overheat and break. By avoiding these mistakes and taking a cautious approach, you can easily drill holes in sea glass.


Drilling holes in sea glass with a little patience and the right tools is a fun and creative process that can result in beautiful jewelry pieces. Remember always to take safety precautions, mark the spot accurately, and drill slowly and steadily. No matter how long, the result will be worth it!
