*  The general rule on drill bit sizes is 3.5mm for non-metal skis and 4.1 for metal. There are exceptions, such as a metal binding plate in a non-metal ski, carbon fiber top sheets, etc
    * By CE regulation, all current skis have the recommended drill size printed on the ski, either in the mounting area, on the adjacent sidewall or on the tail with the ski dimensions.
    * The minimum depth for a screw for a binding mount is 6mm/1/4". Measure the screw less the binding thickness will provide you minimum drill tip length.
    * Make sure this will not exceed the thickness of the ski or snow board.
    * The excess depth of a hole deeper than the length of screw will be filled with the glue.
