Cement fiber siding (CFS) can be drilled, nailed and cut much like wood. Since it is more abrasive than wood, carbide or diamond blades are best for cutting. Holes are easy to make with an electric drill and a carbide tip drill bit. As with any project, good eye protection is recommended. If you are sensitive to dust, wearing a dust mask or respirator is also a good idea, depending on how much drilling or cutting you plan to do.
