You should use a carbide abrasive hole saw for any cement board. Trying to use a standard bi-metal hole saw will only work once, maybe twice. As a plumber, I have to drill through cement board all the time. IMO it's worth it to go to Lowes or Depot to get the right hole saw for the job.

Not a good idea unless it want to ruin the hole saw in record time. Unless you have a carbide or diamond hole saw, hammer drill a series of small holes around the perimeter. Save the bimetal for drilling the wood band board.

I'd use a metal cutting hole saw because it will only slightly dull the cutting tips, not enough to ruin it for future cutting of steel in the future! when ever using metal hole saws on steel always run the drill as slow as possible & use plenty of cutting fluid. Cutting cement board then use no cutting fluid at all! But one word of caution; wear safety glasses & a face mask. Cheers!
