Re: [CAD_CAM_EDM_DRO] using a CNC mill to engrave metal

The biggest factors concerning what cutting tool to use would be the size of
the lettering and what sort of effect your trying to achieve with your
n"engraving". Since the depth of cut is only going to be a few thousandths,
you could do your engraving with a .005" (or so) diameter end mill. If you
wanted the lettering to look more like real engraving, you could you an end
mill with a tapered point.

BTW...if you use a .005 or a .010 dia. end mill for cutting the letters,
you'l have some really accurate letter shapes which can easily be converted
for gold/silver inlay work. Sounds like a great idea for doing lettering
inlay work on firearms.
