Tungsten Carbide angle nozzles for sandblasting are available with one, two or three exit ports. Generally, the two and three port angle nozzles are used for blast cleaning inside tubes or U-shaped forms, where abrasive can only be aimed at side walls with an angle nozzle. Another area where carbide angle nozzles are useful is in getting behind angles on bridge work. Some jobs may need a combination of nozzles to reach inside tight angles or partially enclosed areas. Angle Nozzles are available with forward shooting exit ports at approx. 45 degrees, sideways shooting at 90 degrees and reverse angle nozzles with a port that shoots abrasive at approx. 135 degrees.
