Also used in residential construction and reno's. When you build a wall, you frame your wall on a deck, rack it and sheath it. If that wall has a window or door, then after it is nailed to the framing, then you go back and cut out the doors and windows, before you stand the wall up...
So one of several ways to quickly do that is with a panel router bit. Punch through, Use the framing, as a guide to cut it out.
Also to cut out lower cabinets and vanities, used with a template... to cut out for a sink.
The only size I used to have was 1/2" panel plunge bits.They are handy, utility type of solution of what would otherwise take a few tools or multiple bits., but I never thought of them as a finishing type of bit.
"Don't worry, I saw this work in a cartoon once."
"Usually learning skills and tooling involves a progression of logical steps."
