An inspection hole will allow you to see where pipes and wires are located behind the wall. A cleanly cut inspection hole can easily be patched once your work in the wall is complete, or if it turns out that you don't want to make an opening there after all. When you have identified and marked the boundaries of your inspection hole with a pencil, cut along the lines using a drywall or wallboard saw, which has a very sharp tip. Twisting and pushing the saw allows that tip to penetrate the wallboard when you make your first cut. Hold the saw at a 45-degree angle, as in the diagram, to create a clean beveled cut. Using smooth, even strokes, saw along one of the vertical sides. At the bottom, pull the blade most of the way out, twist it 90 degrees, and begin cutting the next side. Repeat the process on the remaining sides, making sure to maintain the bevel by keeping the saw at a 45-degree angle. Before you cut along the final side, mark the top of the square you are cutting with an arrow inside the square, so you can orient the piece correctly later. A benefit of the bevel is that it will prevent the piece from falling into the wall when it's time to push it back into place.
