I spotted a link to a video from a link someone posted recently, and that
began a series of interesting discoveries of other drill sharpening machines
and methods

Kaindl a German company

Viel a Canadian company, but a location in the USA

You might notice that both of the above methods utilize a segmented chuck?
holder for the drills.
A similar type holder is used for the TDR SRD drill sharpening machines

The segmented drill holder makes it easy for the operator to flip the holder
over and have the 2 drill point sharpening positions indexed 180 degrees
apart (without remounting the drill in the holder).
