Thank you. This looks like an excellent reference. From what I read so far, it would appear that what the previous owner told me is ass-backwards. But I need to investigate more, tomorrow.Does your machine use that grove to hold the tool? If so, you may have one of the other nm tapers. Cat, iso, and 10 million other names.

*EDIT:
It's also equally possible that I remembered his words ass-backwards. I am pretty sure though that he said anything I order must be "NMTB30" and not QC30 or any other 30 taper, because some might work and some might not, but NMTB was the only one guaranteed to work.
EDIT2:
Just realized I completely neglected to answer your question. YES. The groove is used to hold the tool.
