Designed for blasting the inside of pipes, the ConeBlast will blast pipes from 50mm up to 300mm. Abrasive is fed through the center of the tool and deflected outward by a tungsten carbide tip after exiting. For successful operation, you will require 1-1/2″ blast hose and 250 cfm of compressed air. Has high spare parts consumption rate. Allow extra spare parts cost when pricing project that requires internal pipe blasting. Rotating head type pipe blasters also available. See us for internal pipe painting systems as well.
