Matching a drill bit to a screw size: Choose a drill bit that matches the diameter of the screw’s shank (excluding the threads). For wood screws, align the drill bit with the screw; it should be about the same width as the narrow core of the screw. For metal screws, use a drill bit slightly smaller than the screw diameter to ensure a tight fit. Always test on a scrap material to ensure accuracy.
