We are in the middle of our home remodeling and we have just noticed that our ceiling seems to be a bit thicker than what the maximum our recessed lights allow for.
As shown within the picture link below, our ceiling is comprised of different layers (of different thicknesses):
- Lower layer: (visible from the room) made out of sheetrock (5/8in thickness)
- Mid layer: Plaster (3/4in thickness)
- Top layer: Lath (1/8in thickness)
The recessed light container we are using has adjustable clips for different ceiling thicknesses although we have just noticed that our ceiling is too think so the clips would not really sit on top of the ceiling but rather create resistance on the hole.
My question here is if there is some sort of drill bit that, after drilling the initial hole diameter where the container is going to fit in, could expand the hole diameter above the lower layer of sheetrock.
