How to cut a hole through vinyl siding

vinyl-siding

I would like to ventilate my bathroom fan to the exterior of my attic and outside. We have vinyl siding. What is the proper way to cut a hole in the siding?

I have a 4" hole saw for the wood.

The hole saw will do the job. You don't need a perfectly clean cut here because your vent cover will hide the hole.

But - ideally - drill your pilot hole from inside, then drill thru from the outside with the hole saw.
