Top Tips Before You Get Started
Our Top Tips To Remember For Drilling Sea Glass
Start at an angle: Begin drilling the sea glass at an angle and slowly tilt your drill bit upright to continue drilling - this will stop the drill bit from skidding out of position and potentially marking your glass.
Keep it slow and steady: Use at a slow speed with a light to medium pressure, allowing the diamond coated drill bit to go at its own speed.
Drill in water: Use plenty of lubrication by drilling your sea glass in water and rinse the sea glass regularly, ensuring that you are keeping the drill bit and glass cool throughout the drilling process. We recommend adding a piece of wood to the bottom of your container to act as a stopper once your drill bit goes through the sea glass.
Use a gentle pulsing movement: Gently and slowly lift the drill bit up and down while drilling, this will help prevent the glass and drill bit from overheating.
For thick pieces of sea glass: You can drill 3/4 of the way through, flip it over and drill from the other side for a more even hole.
Be patient: If you break a piece of sea glass or a drill bit, don't panic - assess your technique and try again.
Reasons Your Drill Bit Is Blunt Or Broken
When first practising your drilling technique, it's important to follow our advice to prolong the life of your drill bit and avoid damaging it.
The featured photo shows 2 diamond coated drill bits side by side, the right one is damaged and blunt and we share some of the possible reasons for this below.
Too much force was used: Using too much pressure or speed will cause your drill bit to become dull and ineffective. Always use light to medium pressure, allowing the drill bit to go at its own speed.
The sea glass or drill bit overheated as there wasn't enough lubrication: Drilling the hole underwater helps wash away debris and keep everything cool. Don't forget to keep rinsing the sea glass regularly as this will also prevent it from overheating. If the drill bit gets too hot, it will burn off the diamond coating so you with end up with a smooth and ineffective drill.
Your drill bit wasn't upright and steady: Once you've started drilling the hole, keep the drill upright and steady, do not roll it around as this will increase the chances of breaking the drill bit.

Place the wooden board into the tub with shallow water - the board is to stop the drill bit going through the tub. Place your sea glass on top and ensure that there is enough water to cover the board and sea glass. The sea glass needs to be drilled in water to avoid the sea glass and drill bit from overheating and to keep the hole clear.
Set the speed of the rotary tool to low, use your finger to hold the sea glass under the water. Begin drilling at an angle - this will stop the drill bit from skidding out of position). Then continue to drill vertically using light to medium pressure, allowing the drill bit to go at its own speed.
Use a pulsing technique to keep the sea glass and drill bit lubricated, allowing the water to reach the tip and wash away debris. Rinse the sea glass frequently to keep it cool. Using a good drilling technique and having lots of lubrication will improve the life-span of the drill bit quite considerably.
So you've drilled your piece of sea glass, now what? You can transform it into a pendant, charm or use for dangly earrings! The example we show is a simple necklace - it's so easy! Simply get the appropriate size jump ring for your sea glass to attach through the hole, take this into consideration when drilling the hole as the closer you are to the edge, the more room you will have for the jump ring - 7mm jump rings work well for this. In this project, we've used 1mm diamond coated drill bit and If your jump ring doesn't fit, you could also use a wire wrapping technique to form a loop - find step by step instructions here.
