I'm trying to cut a 3/4 inch hole in the side of my RV.
The siding is light gauge tin, or perhaps aluminum, and behind it is pink insulation, so a standard drill bit will not work very well....
I think the right Dremel cutting bit will work well for this but I'd be happy for your suggestion.
I figure to draw the hole onto the tin and then drill a small pilot or starter hole. Then with the right cutter bit, I should be able to cut along the drawn hole and produce an accurate and smooth hole.
Ideas? Suggestions?
Thanks

Ok, maybe I should have checked this our first. I saw the big chart of the different accessories and it looks like the cutters 9901 - 9904 might do the job.
Does that sound right?
Thanks

| My recollection is that the cutters 9901-9904 can leave kind of a rough edge. You might want to try them on an aluminum can etc before tackling the good stuff. I've used the 409 15/16" cut off wheel for similar projects. After marking out the hole with pencil, I started cutting several pie or wedge shaped pieces across the hole from line to line. By then, the cut off wheel has worn down considerably. When it is 1/2" or smaller I use it to make a small cut on the line itself and the wedge piece drops off. For my projects the final cut edge was covered so I wasn't overly concerned from a "looks" standpoint. Good Luck!
