X21 Cutting nozzle A 311-2 10 pack

HA 311 is a 3-cone sealed cutting nozzle, exactly the same as COOLEX® A 311 but without a cooling flow. The nozzle has a cylindrical cutting duct and six heating flames, except for the largest nozzle, 300–500 mm, which has nine heating flames. It is forged from a piece of copper over polished steel mandrels, which produces an even, turbulence-free flame. The smallest nozzle is known as a thin sheet metal nozzle, 1–3 mm, and is characterised by minimal heat spread and consequently little deformation of the workpiece. HA 311 has a large cutting range – a series of eight cutting nozzles for material thickness ranging from 1–500 mm.
