The 8 Best Glass Drill Bits
This wiki has been updated 11 times since it was first published in January of 2018. Glass is difficult to drill into, so getting the job done 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.

Editor's Notes
October 17, 2019:
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!
