I just ran across a most interesting handbook that now sits next to Machinery's Handbook.
that may be of use to some of brethren on this site:
Engineers Black Book, 3d Edition (inches) - Pat Rapp Western Australia
Crossroad Distributor source.
Credit goes to my often visits to great YouTube machining tutorials by ABOM79.
In particular I have finally learned how to correctly identify the correct replacement
for carbide threading inserts for my tool holders.
Learning never stops.
Best
