Could you mean etching?

I suspect a language barrier-drill means to make a hole, etch is to remove metal with a chemical, mill is to cut away metal with a spinning tool, engrave is to remove metal with a non-spinning tool.

You mention draw or write-If you are trying to make a pattern on metal, you want to look for etching or milling.

I suspect you are looking for something like this?
