What size hole should I drill in order to recess the 12V Puck Lights?
Hey buddy , at first you need to choose a good quality drill . I advice you compact drill for example 2702-20 hammer drill by Milwaukee, from https://toolsduty.com very good thing for housework. Everything else is a matter of technique , try to start with a small size drill. And keep doing that until you get the right hole size. That’s all you need to know. I always do that when I don’t know what size to choose.
