Euro/cup cabinet door hinge boring patternsOne thing most concealed euro/cup hinges have in common is that they require a large cup hole and two smaller holes for either screws or some sort of insert. It is possible to drill the large hole on a standard drill press, and then use a drill guide like a VIX-bit. The hinge itself can be used as a template for drilling the screw holes. These hinges require that all three holes be precisely drilled, so a dedicated drill press which is designed for drilling these three holes simultaneously is ideal.
Here is an overview of some cup hinge boring hole patterns in the USA. Note: Hinge boring diagrams are not to scale.
