Probably won't find a Q bit at the local autoparts HomeDepot or Lowes store. Try a real hardware store or industrial supplier. Or just buy the kit that comes with the bit. Oh and 8.5 MM is less than .003" larger than a Q drill so it should work also. http://www.csgnetwork.com/drillsizeconvert.html

thanks.



21/64" is .004" smaller and works. I've done it a number of times,especially on a low torque app like a carb mount flange
