I've seen references to designators like "CCMT 06" inserts, but I don't
know what the specs on those are, or what particular metals/operations

If possible stick with the TPU/TPG holders.

TPU/TPG inserts are dirt cheap. Unless you are in high volume
production using exotic materials the other inserts will not be
cost effective. Coatings are also marginal for home shop use.
Use C6 grade for steel and C2 for everything else. You can even
get mill cutters that will use the TPU/TPG [u = unground, G =
ground] inserts.

One place to start is

Excellent post.

This assumes his machine can take a cut heavy enough to justify

Good point. Big benefit for the newby is this eliminates the
need to grind your own HSS tools, which for home shop use are
most likely an even better choice.
