22mm holes drilled using new Knopp Drill
Along with polishing glass and mirrors, drilling holes is a required process. We have invested in a Knopp double sided vertical glass drilling machine. This machine drills holes from both sides of the glass at the same time, achieving a perfect finish ready to be toughened.
We can drill holes ranging from 3mm through to 75mm
