I am looking for a comprehensive tap and drill chart that covers both US and
metric. I ran into a situation at work where a part was purchased that had
a metric thread pitch that none of the crappy charts showed. Looking
further into this, I realized there are a lot more thread pitches for metric
sizes than I previously knew about.
If you have any internet resources or books that have this, please let me
Thanks for any pointers.
