A Through Hole refers to a hole that is reamed, drilled, milled etc., completely through the substrate. In other words, a through hole is a hole that goes all the way through something. This is to distinguish it from a Blind Hole, which does not go all the way through the substrate.

Examples to distinguish a through hole from a blind hole could be this example:
