You drill a pilot hole then use a step bit to drill the holes for the pass through fittings. The ekwb pass through fittings I used had a 20mm outer diameter so I just stopped drilling once the 20mm step was through. A tip is to use painters tape to mark the bit where you need to stop in order to prevent over drilling. I used a drill/tap combo bit and some m3 screws and nuts to drill and tap the screws for the res mounts on the mounting plate.
