Tungsten Carbide Sandblasting Nozzle If you are looking to save money on Sandblasting Nozzles, try one of these! I began sandblasting a few years ago and purchased what were sold to me as carbide nozzles. I paid $45.00 a piece. They would last me 1-2 months. A friend of mine works in a machine shop and said he could make those nozzles out of Tungsten Carbide. I ordered 10, 2 years ago. I have only used 4 so far and the one I'm using now is still in good shape. Try one of these for $33.00 and see if it doesn't outlast the others! Best part about it, it is "Made in the USA"! The cfm is approximately 10-15. It is 1/4" on the inside diameter of the smaller side and 3/8" diameter on the larger side. The outside diameter is 1/2". The length is 1 1/2".
