Actually, most engraving *is* done with a rotating bit, usually fixed,

stuff like anodized AL is also rotary cut (or lasered). Drag engraving
is the exception, not the norm.

Iggy will find a high speed spindle and a nice carbide rotary engraving
bit work nicely to engrave lettering and markings on aluminum or plastic
enclosures which can be paint filled for a very nice result.

Which brings up a question, how do you paint fill them? What paint etc

When I was doing engraving (Gorton, Hermes, Green 106), I would use an
Enamel Paint Stick (tradename: Engravocolor Sticks).

It fills in the engraved lines with a medium-soft enamel, that would
harden.
