Even if you don't have a core drill, you can drill a φ100mm hole with a disc grinder. The stony imitation wood is about 30mm thick, but you have to open a clean cylinder. The holes are for recessed LED spotlights. Unfortunately, the spotlight holder needs to be embedded first, so it is necessary to adjust it with an offset spacer to attach the main body. Since there is no special spacer, we will use a vinyl chloride pipe for drainage and process it. For processing, you have to cut it with a grinder or heat it with a cassette torch to fit it to the object .
