Can you drill holes in glass? Can you drill holes in glass that I bring in?

We can drill a variety of hole sizes in annealed and laminated glass, and can also fabricate square holes to accommodate outlets and cut inside corners.  We are happy to drill holes in your glass, but cannot guarantee breakage will not occur, since we do not have control over the glass quality. We will not replace glass if it breaks while we are drilling holes or doing any other fabrication.

Because it cannot be modified, tempered glass needs to have holes drilled in it before going through the tempering process.
