Sommerfeld's 3 Piece Tongue & Groove Cabinetmaking Set, 1/2-Inch Shank

Can these be used for making tongue and groove doors? Is this set supplied with different bearings?

Hey guys, does anyone know how this set compares with the new sommerfeld "made in america" version of the same bit set for $150? worth it?

I'm starting from scratch here, what should i look for in router / routing table compatibility? i know nothing. would the amazon suggested bosch fit?

It is not stated here, but the key to this is to keep the good face down. The tongue and groove leave you with a perfectly aligned front. Right?
