What tooling are you guys using to engrave text into a part on a VMC?

for small stuff I use a #2 center drill about .005 - .010 deep

for larger stuff I use a .125 ball nose EM. about .010 - .030 deep all depending on pref.

I find that the center drill will leave a small rough edge.  I like using a 5/32 ball nose endmill .003 to .005 deep. Depending on how wide you need the engraving.

1/32 ball nose or a half round depending on line width. The part #'s we engrave are pretty small.
 
Recently a customer wanted us to mill .200 high characters with .020 line width .040 deep so he could fill them with paint....... In a sheet metal panel that wasn't real flat.......... I did it, but I'm pretty sure he won't be doing that again after what we charged him........
