Review on 🔧 Adjustable Aluminum Alloy Cabinet Hardware Jig Power Tool Punch Locator - Wood Drilling Dowelling Guide for Effortless Door and Drawer Handle Knob Pull Installation by Brett Martinez

Available in mm and inches. Important because some don't and the hardware goes both ways. Hassle-free installation of about 65 3" center straight bar handles on drawers and cabinet doors. There may be issues with some decorative recessed or raised panels and drawers. I used the metal bushings to make the holes with a drill bit but then I drilled them free hand to avoid drilling out the bushings and once completed they showed no wear. Very pleased.
