Zusammenfassung:	A pneumatic spindle with coolant through to the cutting bit is described. The pneumatic spindle includes a shank with a shank first end (USMA). A rotary union housing that is adapted to rotatably couple to the shank. A floating rotary union seal is rotatably coupled to an internal passage of rotary union housing. The rotary union housing includes a second end formed with a threaded circular opening and the pneumatic spindle first end is threaded to rotatably join with the threaded circular opening of the rotary union housing. The floating rotary union seal includes a first end, a floating rotary union seal second end and a floating rotary union seal internal passage. The floating rotary union seal second end formed as a circular bearing surface, and the floating rotary union seal internal passage directs the coolant fluid between the floating rotary union seal first end and the floating rotary union seal second end.
