I have been asked about putting in a couple of network cables that need to go through the internal walls of a building. It appears to be constructed of large prefab concrete slabs, I guess they might have rebar in them but no one knows for sure. I have reasonable access to both sides once the false ceiling panels are moved.
Any advice on how best to drill something like a 10-20mm hole for the cable(s) to pass through?
