Re: Adventures in Finding Small Files—an update

Bill, perhaps watchmakers use the terms differently but as a machinist, reamers and broaches work differently.
Both modify the size or shape of a hole but a reamer cuts with a rotary action. A broach is pushed or pulled
through a hole cutting in a linear fashion. 
At least this is true of all that I have used.  I now expect someone to come up with the exception.

As a bonus I have also seen some really small reamers or broaches using the term watchmakers use.
