Can Durarock be scored/cut with a blade. I need to take a section out that is already installed (no tile yet) and replace it with sheetrock (it is going to be a painted surface. I do not want to kick up a lot of dust with a diamond blade if at all possible.
Thanks,
David

Scoring only works if you can bend it so it will snap and break on the score line. What you are trying to do is cut a hole. You can try a drywall/keyhole saw after punching a couple small holes in the corner of the cutout but this will pretty much spell the end of your saw. If I'm allowed to back up a bit, I would not suggest putting a piece of dry wall in the middle of your concrete board. The reason for concrete board is because it is highly resistant to water. This is not true at all for drywall. It will desolve. If it is just because you want to paint it, use a paint that will hold up in wet conditions. Remember that water will be coming at it from both directions.

Not sure where the idea of a hole came from, I didn't see that in your post. If you are just trying to cut a section off or out of an installed sheet, you could probably drill a series of holes on a line you mark, then knock it out with a hammer or use a jab saw. A small masonry bit would last longer, unless you have a bunch of old ones you don't care about. You'll still have to trim the mesh after the cement material is broken, and it's won't be a super clean cut, but since you'll be butting up to it and taping, will that matter?
