Collection: Diamond Drill Bits for Glass Art

We offer a wide range of diamond drill bits for drilling holes in glass. Our Diamond Core Drills and Small Diamond Core Drills allow good circulation of water and will stay cooler whilst drilling. Our Bottle Neck Core Drills have a 2.35mm shank.  Our Small Diamond Drill Bits have a solid end and therefore a wider surface area.  Whether you are drilling holes in glass bottles, fused glass, sea glass, stained glass, cast glass, cold glass or de-misting windows, we have a glass drill bit for you. These are premium quality glass drill bits, do not be fooled by cheaper imitations. If you're looking for a glass drill bit, Eternal Tools has the right diamond drill bit for you.
