One had to ask,you never know
Very true
One had to ask,you never know
stand corrected trepanning tools do go that big but it will be still messy using it on a ceiling I use a plastic chinamans hat with cutters on the celling to collect the dust
Drill pilots from below, 2nd person stands up ladder holding cardboard box pressed against ceiling, drill from above - no mess.
Mines bigger than yours.

Trepan was my first thought too.
400-600 centers these days.@printcom whats the ceiling joist spacing 285mm holes if standard 450mm centres is a big hole
I'd use a combination of both.I once borrowed one similar to that from a site sparkie to cut holes for ceiling speakers, they do work well until you hit a bit of top hat when they grab and make a right mess, I think I did two or three 180mm ish holes before I gave it back and returned to using a pad saw.
It was a health club in a hotel on Park Lane, must have been thirty speakers of various sizes, after a while you get quite quick with the pad saw.
Best to avoid the really aggressive ones like the Fat Max and get one with smaller teeth, to begin with they are slower but much less tiring.
I'd use a combination of both.
Use the trepan to mark and part cut the holes and finish with a padsaw
It says Silverline so might require 1 per hole
yea its lifetime one day if your lucky"Lifetime Guarantee"

What on the packaging?
The router comment jogged my mind, I forgot I had this, did a great job I just measured and cut the holes before putting the board up. Its easy with a board lifter.View attachment 196958
You'd be lucky to miss joistsI need to make around 40 285mm holes in 12.5mm plasterboard for some lights. I cant seem to find a hole saw that size that doesn't make me wince. Any suggestions?
