I have been cleaning out a box of reamers, I must have 50 reamers that are
..381 to the best of my measuring, all look new with protective coating. It's
possible that some company had a use for these that wasn't to common but
they all look new, is there some standard use for this size?

Clearance for a 3/8" bolt or pin?

This sounds like an oversized reamer for 3/8. Usually, however,
oversize reamers are only 2-3 thou over, in this case this would be
..378 or so. It is possible it could also be a 10 mm undersized reamer.
Is the shaft size metric or standard? This might indicate whether it
is the standard or metric reamer.

its a MT1 shank, not sure how to read the #s on the them
