I ordered a metal engraving bit.

I was surprised when I opened the bit. I sell these. The manufacturer states that it will cut Al but I have never tried nor suggested anyone to use it for that.

Let’s see if this is going to teach me something.

Have you tryed them yet?

I did, these will more etch a sheet of Al. Not so much on the engraving end…
