How to Drill a Hole in a Mason Jar

Glass is the most difficult material to make a hole in, because one wrong move can create a long hairline crack, or shatter your glass altogether. But with the right drill bit and a bit of extra care, you’ll be ready to pop holes in jars in no time.

The Tools

Already got an electric drill? Excellent. You’re halfway there already. Now you just need a specialty drill bit set meant for stone and tile. And of course, glass.

Those pictured are from HK, sold on Amazon. It’s much safer for both you and your equipment if you use the right drill bits for the job.

Liquid Cooling

Drilling through a jar is quite unlike drilling through a 2×4. For best results, you’ll want to keep your drill bit and the drilling area cool with water. A spray bottle set on “stream” is perfect here if you’ve got one.

Patience!

Depending on the thickness of your jar or bottle, it could take as few as 5 or as many as 20 minutes per hole! The faster you go, the more you risk making the sort of error that will cause a hairline fracture in your glass.

It’s a Little Bit Messy…

Drilling through glass creates a fine powder of, you guessed it, glass. It’s fine enough that it’s not going to cut you – but keep that stuff out of your eyes!

Best to use safety equipment like goggles, and to do this outside or in the workshop if you have one.
