Don,

as you said, these type of drill bit is only for machine use. Meaning they are chucked in a drill which is mounted onto a drill press:

We had a Dremel drill press that would lock in a Dremel tool so they could drill hundreds of holes without losing a bit. Then when it came assembly time they might find a hole they missed and tried to drill it out holding the Dremel tool..... they had about a 20% success rate doing that Some of the boards we made were far too large to use the small drill press on (24" x 36"), and they'd try to chuck a small bit into the large press.
