Could you use a router at slow speed with a small 1/4" endmill on

1/4" spiral up carbide woodworking bit?

I have used a router on aluminium. But only to camfer edges. Works great
with woodworking carbide bits.
I wouldn't try it on steel.

If you intend to use it for engraving: Pay attention! The bits for handheld
routers do have a chip-limiter (right expression?) and you can't use normal
metalworking bits for that!
