What Die Grinder bit to use? Need to enlarge antenna hole in fender
I ended up using a double cut carbide burr 1/4” x 3/4. Worked like a charm with light gradual passes. I etched the paint first to creat a sharp edge to prevent excess chipping etc…
the metal stayed nice and cool. I think a stone/drum sander would have taken a long time and created a lot of heat. Made a little bed of tape, sticky side up, to catch chips and filings from going into the bottom of the fender.
