Congratulations Scap. I have a number of Sommerfeld bits and I really like them. Freud also makes good bits. The tongue and groove bit can also be used to cut grooves on both sides of the joint, then use a fitted piece of wood as a "spline", which makes a really great joint, very strong if the grain goes crosswise to the grooves.
When you get a chance, go look up Marc's videos on using his bits. He was a cabinet maker before offering tools, and his technique is very simple and extremely good. I bought his full video set early on and love to watch them, especiaially before I do a project he's covered.
Routing on a table is far safer, and of course you should never use a large bit freehand.
Don't you love the wooden bit cases? Don't forget to put the half inch grommet into the collet for matched bit sets.
The more I do, the less I accomplish.
