Does anyone know what drill bit size spot weld cutter is for removing spot welds on mustang floor supports?

The gold colored titanium coated bits as seen in the link above are my favorites.

I got my spot weld cutter from Eastwood years ago and it works GREAT ! A 3/8 drill bit will work but you lose the metal in the second layer of sheet metal. The cutter is well worth getting (get extra cutter heads too just in case you dull the first one).
