I have a pair of CJ turn signals I'm going to add the grill of the TJ. I like the looks, only reason. Well another reason is because I can. I have to cut a 3.5 inch hole in the grill for the lights to recess/fit. Here is the question I'm pondering. As it requires I buy a tool to do a clean job, which to buy? The $290.00 Makita cordless nibbler or the $110.00 carbide hole saw? The nibblers cut up to 16 gauge which should do the trick and the tool would be a good weapon to have in my arsenal. The carbide hole saw may be a simpler endeavor, but doubt I'd ever use it again. Thoughts? Other options?
