OD of 4" schedule 80 pipe is 4.5", so that's what you'd need to cut out the stop and turn a regular coupling into a slip coupling, might get by with 4 3/16" as the hole saw can wobble a bit when you don't have a pilot hole. If you're unsure, just measure the OD of your pipe, as that is what will have to fit thru the coupling.
It should. I used a Dewalt mandrel. I think mandrels may be interchangeable.

It is not designed for ceramic cutting (eg a diamond cutting surface). This saw also lacks carbide tipped saw blades that can be used for cement boards. (e.g. as used in a table saw). Still, I would expect it to cut a few holes in cement siding before the blades become dull. If you only need to cut a few holes this might be the lowest cost solution.
Great quality and strength
