NukaTap Mini - Wall Mount Shank Kit (duotight 8mm 5/16)

Unlike other long shank kits this kit doesn't require large 22mm hole saw to be used to drill through the wall. As no shank is required only a hole large enough to accommodate the beer line is required. As a result only an 8mm conventional drill bit is all that is necessary and this makes the installation easier. If however you are concerned about the small amount of beer sitting in the beer line in the wall not being refrigerated you can also shell out a larger diameter of foam on the inside of the wall to allow cold air to circulate around the beer line thus reducing the non-refrigerated beer in the line even more. If you wanted to do this the Step Drill Bit is the best tool for the job.
