I've had some downlights fitted but to cut a long story short, they're the wrong ones.
As the ceiling is on a slope I need adjustable downlights, however the hole for them needs to be 85mm instead of the existing 72mm
What's the best way to enlarge the hole? Will I be able to use a hole saw as there won't be anything for the arbor bit to grip into in the middle?
Thanks
