Short Nozzle with Small Hole Diameter (3mm)
The short nozzle with the smaller hole diameter (3mm) is mostly used for cutting materials that may create an excess amount of smoke, like wood. Due to the small opening, the concentrated airflow is directed into the kerf, blowing away any emerging smoke and cutting the gases, ultimately protecting your machine from damage. However, this nozzle is not suitable for dust-intensive materials, like plastic and rubber. The engraving dust tends to settle at the opening of the nozzle and has a bad habit of blocking it. This can then cause burn holes in the lens.
