Best cutting disc for fibre cement corrugated sheets?

[steveR]

I am going to be fitting new steel box profile guttering on a workshop, clad with fibre cement corrugated sheets.

I need to cut out slots in-situ, to access the steel stanchions in 4 locations, to fit support brackets as I cannot take down the sheets easily. What is the 115mm best disc for the job? Stone abrasive cutting disc, or diamond tipped discs? Or summat else?

FC sheets. I put them up 20 odd years ago.

long time since ive done some stone disc would make sense, have used a 'dildo' saw (that's from @milkloss ) before as well iirc.

Hmmm, well I did ponder a reciprocating saw, but no room to use it. However, I will never look at one in the same light....

Will probably just pick up a pack of cheapie stone discs

Would a multi tool do it

Doubt it, it's very tough stuff!

I reckon a vibrator would do it with the right blade.

Diamond tipped discs stay same diameter all the time. Better cutting than abrasive ones that wear down.
Squirty spray of water to keep dust down, whatever it is.
