Test # 2 : This time I tried a 1.750" bi-metal hole saw on the Chevy II dash. My angle of approach was approx 45 degrees on a section that has a large curve. (ie the leading edge from the driver's side). Drilled a .250" pilot and ran the saw in reverse as before using a small amount of dish soap as lube. The hole went perfectly until the teeth met a sheet metal reinforcing panel. Note: The pilot hole missed the sheet metal as the metal is only a narrow strip. This caused the hole saw to jump and that tore up the vinyl. Tried again stopping just as it met the steel and another perfect hole. I think even if the pilot hole went thru the steel, I would stop because more than likely the angle of attack would be something other than 90 degrees and it would be difficult to control. Can cut the metal from bottom side or reach in with a die grinder.
