These are pretty small, they are the size of a quarter, roughly.

As I recall..and I may well be wrong.....

They are the replacement ends for a larger group of units, boring bars,
boring heads and so forth.

They were commonly used in automated machining as "quick replacement"
heads. If you busted an insert..you simply replaced it with another very
quickly. The advantage was that each was exactly the same size as the
privious unit, so didnt need to retouch your tooling offsets

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost
