| Hello, I'm planning to cut into my aluminum hood to install some vents to channel air to the turbos. The GTR hood scoops appear to fit the bill. It's an experimental project and if it fails, I will get a new hood. I need to know what type of cutting wheel (or disc) to specifically use for the aluminum. My Black and Decker rotary is this (and it fits a varitey of Dremel grommets): [ http://www.blackanddecker.com/ProductGuide/CategoryOverview.aspx?cPath=1496.1508 ] I see a variety of discs made out of diamonds, carbide, etc., and am confused. Thanks in advance. Jack
