Plastered Ceiling

[aarondiyer]

Hi - I have just had ceiling plastered - I have never cut holes in plaster before but am not to bad on diy. The ceiling was overboarded so I have cut bigger holes out of the lath plaster and measured with laser. I can also access from ceiling.

I want to know if I drill from the loft downwards to make a pilot hole is that ok to do - then I planned to buy one of those hole cutters. I do not have a speed controlled drill and the teeth on the hole cutters I have seen look really jagged - will they not wreck the plaster? When I look it up on line all the videos are cutting holes using these tools are on non plastered ceilings and just plain old plasterboard. What happens if I use a whole cutter on my drill with the ceiling plastered?

I am thinking of doing the holes with either this:

or one of these (but the teeth look like they would shred the plaster.... has anyone experience of using these on a plastered ceiling please?)

I am guessing this is for downlights? Just use a hole saw.. It will go through plaster and create a clean finish. Tip is go backwards on the drill at the end, that way you are less likely to cut any cables above..

As above, you'll be fine with a hole saw.

Make sure you know where the joists are so you don't cut into them.

and any small chips in the plaster will be covered by the downlight's bezel.

A brand new decent hole saw will go through plasterboard like a warm knife through butter

and get yourself one of these, saves you getting a face full of dust and detritus.

Wouldn't drill from the loft downwards as there'd be an increased risk of bigger chunks breaking off on the edges of the ceiling surface as the hole saw breaks through. A pilot hole from above would work though.

I use one of those, but you have to remember to lower the drill vertically from the ceiling or all the debris falls out onto the floor, done that more than once.
