Armed with only our Concealed Hinge Drilling Guide and a hand drill, you can drill perfectly positioned cup holes for your concealed hinges. Since there’s no need for a drill press, you’ll save both money and space in your shop. Each guide now features an integral spring clamp that holds the guide in place as you drill. No adjustment is required for the clamp, but more importantly, the clamp also doubles as a foot. It is designed to rest on your benchtop (or the floor) and provide firm support as you apply downward pressure with the drill bit. To support the other end of the door, simply use scrap blocks or Bench Cookies (sold separately). A long shank Forstner bit (sold separately) to match your hinge cup size is required to use the jig. Carbide bits are recommended.
