Yep, it will do it with no sweat. Probably either a high-speed steel wood rasp or a carbide rasp used for cutting ceramic tile would do the trick. Just don't try to use a tiny Harbor Freight rotary tool, etc.I thought about a Dremel, but I assumed it wouldn't be powerful enough to bore through 1/2-5/8" of fiberglass. Will it? I don't have one, but I am sure I could borrow one.
Chuck the male end into your drill, put a hex-end drill bit in the female end of the flex drive. It lets you get the drill out of the way and align the drill bit very close to parallel with the green surface.
- I don't follow how a flex adapter would work for my situation?
