The improved blast nozzle comprises an inlet portion, an outlet portion and a square venturi orifice connecting the inlet and outlet portions. The inlet portion includes a square inlet for receiving the air and abrasive particle mixture with a pair of opposing flat top and bottom walls and a pair of opposing flat lateral walls. The opposing flat top and bottom walls and opposing flat lateral walls form a four sided pyramidal shape which converges to the square venturi. The outlet portion is similarly shaped and includes a pair of opposing flat top and bottom walls and a pair of opposing flat lateral walls. The opposing flat top and bottom walls and the opposing flat lateral walls form a four sided pyramidal shape also which diverges from the square venturi to a square outlet for directing the air and abrasive particle mixture. The nozzle body is typically constructed of an abrasion resistant material such as tungsten carbide. The nozzle body is then placed within an outer metal shell and a shock absorbing elastomeric material such as urethane is then cast between the nozzle body and outer metal shell to form a protective layer. The outer metal shell has threads formed on the inlet end of the nozzle to allow connection to a standard air supply line.
