Flexible hose systems connect to the coolant tank of a compatible machine to direct the flow of coolant close to where the tool and workpiece meet, which reduces wasted coolant and provides efficient lubrication and chip removal. The hose flexes for hassle-free positioning and resists vibration to stay in place. Flexible hose systems are modular and can be lengthened, shortened, or used to create branches in a lubrication system to fit a specific application.
