Plastic Flexible Coolant Pipes have been primarily used to spray coolant or washing fluid for machine tools, especially in CNC cutting applications, to prevent damage to both material and bits. If coupled with a air compressor it can be used to clean flammable debris away from laser cutter/engraver marking point to achieve professional results. Another benefit is their articulation, they can be used in a multitude of different ways and angles as well. You can even use them as extra arms for a third hand.
