Hey Mr. Itchy!
Ok, I'm a dremel guy but I hear you on the fiber glass. When you go to drill the hole for the fuel dot? If thats what you are using, have you ever tried a uni bit? Pre drill with a small drill like a 1/8" and take her up from there. Since there is no spiral it tends not to pull on the fiberglass and try to crack it. I actually use them on my wood too where I can.
I like these things for the dremel, to cool! Come in a few shapes.
