drilling through a glass brick

gogwmosJanuary 20, 2012

How hard is it to drill a 5/8" hole in the bottom of a glass block? Can I use my regular drill or do I need a drill press? Also, what tips do you have while drilling? One thing I heard was to immerse the block in water while drilling but obviously don't let the drill get in the water.

Hi There! Welcome aboard the forum! What is your project gonna be? I have even used my tile saw to cut a hole in the glass blocks. Thus it has had water involved as water saves the glass drill bit/saw blade.

You need a drill bit for glass for your regular drill. It's a slow process, and you can put water on your little bit as you're slowly letting it do its thing. I've seen instructions that tell you to start w/a small hole first, then enlarging slowly, so you might need two or three drill bits.

I drill glass block and bottles to insert LED Christmas lights. Regular steel or carbide bits just chip the glass and break it. But it's a very simple task with a good diamond drill bit and some basic instructions.

With a good diamond drill bit and the right techniques it takes about a minute per hole. I've drilled hundreds and never broken one...
