I didn't use the CNC of my machine with the 1/32" end mill. The operation I used one on was that "sight leaf" that I'd made for dallen, milling the graduations. While the end mill was cutting full width is was only .0075" (about 0,2mm) deep.

I fed it by hand on the job.

Ahhhh, OK. Still, you must have a very deft touch on the handles. 

I equate that to drilling a #80 sized hole on the mill using the quill feed. You certainly can't "feel" how much pressure you are putting on the drill with all that mass. (Thank goodness for sensitive drill chucks!)

Even at a .0075" DOC, it takes some real talent and experience to not have snapped such a tiny carbide tool.
Ditto on what David said about the job you did on his sight ladder. Excellent.
