a venturi nozzle is more eficient than the strait ones. they use less air and have a higher velocity and theres a wider spread of media. a decent carbide 6.0mm nozzle will cost about £75.oo ish. theres tungsten carbide and boron carbide boron carbide lasts 3 times longer than tungsten but for home use tungsten will last yearsHi, can anyone point me in the right direction for a 6mm tungsten carbide nozzle, for the right money?
Also whats the diff between a straight and venturi nozzle?
