I'm sure there are numerous power tools for the purpose. I recently needed
to cut a circle and some other small cuts in 1/4" hardy board, and just used
a keyhole saw, which worked fine

*I first used a scoring tool with poor results. Then I tried my angle
grinder with a masonry blade. It cut nicely, but dust was everywhere. I
then tried a diamond blade in my angle grinder with similar results. Then I
used my little 3" battery powered Makita circular saw with a diamond blade
and had very little dust flying around.

Use a respirator when cutting this stuff.

If the only tool I had was jig saw, well I would try that.

A respirator is overkill - it's just a little dust, right? If you had
the little 3.375" Makita with the water drip bottle you wouldn't even
need the dust mask.

Do you mean Hardibacker? If so, they sell a carbide tipped scoring tool,
but a regular razor knife works fine, it just needs replacing fairly
often.

But the key is to bend it backwards of what you do for drywall. Score on
the line, then prop the Hardiboard on a 2x4 on the far side of the cut
and step on the cut to *close* the score, not open it up like drywall.
Then bend it back and it will snap.

*I have the drip bottle, but that dust is so fine that I was not going to
push my luck.

I used my carbide bladed circular saw. It did fine. It has a cheap HF
blade that holds up very well.

I used a 6 tooth Irwin I bought from the local hardware store for $15.00.
You can also get it at AMazon:

It wasn't as dusty as I thought it was going to be, but still wear a
respirator and do it outside.
