The Brass ball adapter locks into any standard 14mm CNC machining lathe or mill via the locking screw like other Brass ball nozzles. The advantage of the Loc-Line ball adapter is that it connects with the original 1/4 inch modular coolant hose system and the unique Loc-Line high pressure turret (HPT) nozzles. The 14mm ball adapter brings the proven adaptability and versatility of Loc-Line to some machines like CNC lathes that only have screw locking spherical coolant nozzles. Using the ball adapter increases the coolant flow options.
