A precision drilling jig for installing concealed cabinet ('euro-style') hinges accurately and quickly. Features tool-free inset positioning for rapid setup and pilot hole guides to ensure perfect hinge alignment. For use with a standard Combi Drill. Includes 35mm TCT machine bit. Features include a Pilot Hole Plate for perfectly square hinge mounting, a Pin Guide System to minimize setup time and guarantee positional accuracy, and a Glass Fibre Reinforced Nylon Body for reduced weight and maintained strength. The Spring-Loaded Drill Guide prevents the machine bit from damaging door surfaces, and a large clamping area secures the jig during use.
