The 10 Best Glass Drill Bits
This wiki has been updated 15 times since it was first published in January of 2018. Glass is difficult to drill into, so getting the job done usually requires a bit made of an extremely hard material, a steady hand, and some lubricant. The hardware we ranked varies considerably in size and function to suit different uses, but all should work without shattering your item to pieces. Remember: due to the intense heat produced, even the best options won't last very long. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki. If you'd like to contribute your own research to the Wiki, please get started by reviewing this introductory video.

Editor's Notes
February 01, 2021:
Without obvious need to remove or replace any of our previous picks, it was a fairly uneventful round of updates. We did, however, find room on our rankings for two new additions. The first option – the Johouse Professional – is a versatile, six-size set that, in addition to glass, can drill through everything from plastic and wood, to tile and masonry; the second option – the Celynd Hole Saw Set – caught our eye with its inclusion of a useful jig, to help prevent drift and keep your hole saws on track.
If you’re shopping in this category, chances are that you already own a drill, but if not, you might want to check out our list of Best Brushless Drills. And once you’ve gone down that road, you may want to check out our list of Best Drill Bit Sets, for less specialized applications.

During this update, we eliminated the Brackit 6-Piece, due to availability questions. At the same time, considering that this is a drill-bit category, we added two new drill-bit options – the Drilax Assorted Pack and the Homeidol Six-Piece Set – to supplement some of the excellent hole-saw-based options these rankings already included.
Something to consider while cruising through this category:
Read user reviews critically and, when it seems appropriate, take the with a grain of salt. As anybody with experience in the matter will tell you, drilling through glass is an arduous process requiring both an abundance of patience and technical proficiency. With such a stark contrast between user reviews in some cases – with positive reviewers gushing with praise while negative reviewers protest that they broke their bit the first time they used it – it’s tough not to wonder how much of this misfortune is resultant of human error.
Drilling through glass isn’t the same as blasting a quick hole through a 2x4. It takes a while (sometimes a matter of minutes). It requires consistent, gentle pressure. A cooling agent is ideal, and indeed often necessary to get the job done (water will usually do). Tempered glass is apt to shatter even if you check all those boxes. So, if that’s a job you’re considering, I suggest you go wide.
Remember the age-old maxim of glass drillers everywhere: be safe, be patient and have some fun. Pick one of these rankings, and get the job done!
