To determine the size hole to drill, check the requirements of the screw or bolt you're using. For precise drilling, refer to a drill bit size chart, which matches the screw diameter with the correct drill bit size. If handling wood, ensure the bit is slightly smaller than the screw's shank. In metalwork, the bit should match the screw's diameter exactly.
