This was recommended to work with a see through janitor. The drill was not deep enough to go through the door and it took several cycles of drilling, then draining, and drilling again to complete the job. Because of this, it was far more likely that the opening was not perfectly orthogonal to the door, resulting in the viewer not being properly positioned. I had to fiddle with the handle to get the mount to work properly. It's not the right tool for drilling a hole in a door to precisely fit something like a peephole.
