What's the best Dremel bit for engraving aluminum? Answered

I want to engrave a design into a block of aluminum with my Dremel. It needs to be about 1/16" deep and 1/16" wide and consists of curves and lines. What is the best bit to use?

I would use a steel tapered cutting bit with either mineral oil or sewing machine oil to lube the bit.

Something with fairly coarse teeth. Lubricate the metal with kerosene, mixed with enough clean engine oil to thicken it a bit. This'll stop the metal clogging your cutter.
