One hardened steel SwiftTool Carbon0.6 for use with all kinds of filaments including abrasive filaments like proCarbon™ and proGlass™. The Carbon0.6 is marked by a black cable, so you easily can separate them from the other sizes.
This is an upgraded version that is moulded with a Silicone shell to lessen the material sticking to the hot end and also protect the delicate cable for longer life. You find the old type ZX726 SwiftTool™ Carbon, 0.6 mm hardened steel nozzle.
The Silicone shell will normally wear down by time, depending on handling and use, but it will still work.
