What the heck is that. I noticed that label today on a box of
inexpensive drill bits that I had thought were Tin coated.

Probably is, and either a Chinglish translation, or from some marketing
'whiz' that isn't very astute in technical matters. I have noticed
however that the TiN coating on inexpensive drills looks nowhere near as
good as on quality stuff. Assuming the cheap tools really do have a TiN
coating... Don't know if it's something else, a poor job of coating, or
just a very thin flash coating. Or some combination of the above.
