Compressed Fibre Cement Flooring

[jimc]

Has anyone played around with compressed fibre cement floor sheeting?
I understand to cut it needs a circular saw/angle grinder with a diamond blade but how would I put a 95mm circular hole in the middle of it?

I am doing my bathroom and have to replace the old floor....been too wet for too long and its turned to wet mushy baltic pine compost.

This is my favourite way to cut the hole:

using a masonry bit, progressively drill holes round the inside of your marked circle - the holes should be fairly closely spaced. Once round, tap out the waste and clean up the edges with a half-round file.

Tip: when drilling the sheet, make sure you have a block of waste wood under to prevent tearout.

Hi Jim,

If you go to the tile section of your local hardware store you can pick up a cheap hole saw designed for ceramic tiles. Basically just a pilot drill with a cutter bar adjustable to the arc of your choice, a bit easier than multiple holes and cheaper than a proper hole saw.

I have cut holes in cement sheet for years using a jigsaw with a metal cutting blade
