cutting cement board - Cooler - 03-16-2020
I am installing a new bathtub surround. I will be using cement board. I will only need to make a few cuts so I do not want to invest heavily in new equipment. I am hoping I will only need a special blade for one of my existing saws.
I have available:
Circular saw
Jig saw
Sawzall saw
4½" hand held grinder
Multi-tool
Carbide hand scoring knife (originally purchased to size formica)
Suggestions will prove helpful.

I've only done it a few times. As I recall, all it required was to simply score it with a common utility knife and then snap it off. Scoring on both sides might result in a cleaner break. A little clean-up might be needed.

You can score it several times with just a utility knife and break like drywall or a carbide toothed wood blade in the circular saw will work but very dusty, outside only.
Any of the tools you listed will work fine for a few cuts ,but will ruin the blade so don't use a good blade. Roly

Yes most carpenters will use standard utility knives. Any use I have used a carbide tipped utility knife blade. Just lasts a little longer.

As said above just scribe on both sides and snap like drywall. They do make a special blade for cutting cement siding that works well, it has only 4 carbide teeth. Use only outside and with a dust mask, lots of silica dust.

Thanks guys. I bought a box of 100 utility knife blades a while back, so I am set for the straight cuts.
I guess I use a ceramic cutting blade for my 4½" angle grinder for cutting notches, etc. Please correct me if I am wrong.

I lay it flat and lay a 4ft level on it. Stand on the level and score along the edge. Wear Shoes!

Since you already have the angle grinder with a ceramic cutting blade, I would use that. It will make a lot of dust, but will be much easier.
