Makehole-no "through"option

I am trying to punch a hole through a poly surface and can’t find the through command, also the holes that i am managing to create have very ragged edges, file uploaded for anyone who can help me.

At the command prompt, when asking for the Depth point, you can hit Enter to have the hole go through the object. If you join your surfaces into one object, Rhino will be able to figure out how far it has to extrude the hole to get to the back side of the plate.

As for ragged edges, you can control those in the mesh setting under the Document Properties.
