SwivelJet makes flexible coolant delivery lines and nozzles for CNC grinding and machining, developed over two years in close consultation with machine operators. Its solid-brass lines combine adjustable positioning with a rigid hold, while coherent-jet technology directs coolant to the work area and can reduce cycle time and heat during grinding. Based in St. Henry, Ohio, the company also introduced its hand-tightened knurled system in 2010.
