Despite the German name, this set is (obviously) made in China. My first use of the kit was to realign bolts after plugging old holes in door hinges. Without this tool, it is common for the pilot holes to be off center. This does not happen with a self-centering drill. The set is good, not sure if the polish will rust or not as often happens with cheap tools. The box is ok but it would be better if the material was stronger and the cutout was the right size. Maybe I'll try to make it out of wood on the CNC.
