Just putting this out there so people are aware. I saw this photo on Amazon included in an ad for a tongue and groove router bit set. The photo shows the bit able to make smooth bottom plunge cuts. This is not possible with this bit. It also shows it able to be used in a drill to do this. I’m not 100% sure a router bit couldn’t be used in a drill for some things but I don’t see this one doing it. Drills do not have the RPM’s that a router has even on its slowest speed. Having not tried this, and knowing that a tongue and groove bit is designed to contact wood from the side I could see this particular bit acting more like a wheel and skipping along the surface at drill RPM’s.
