E3D Nozzle X 1,75mm

This is the original, not a china copy. 

V6 nozzles are designed for use with the E3D V6 heater block. Modify your HotEnd to be able to print with small nozzle orifices to achieve fine details or larger nozzle orifice sizes for more substantial, stronger prints. 1.75mm V6 nozzles are fully compatible with the Prusa 3D printers.

Nozzle X is the last nozzle your 3D printer will ever need. Made from a hardened tool-steel base, they are then Nickel plated to maintain hardness at elevated temperatures, and have a WS2 coating applied to provide the nozzle with reduced stick properties. Rated to a maximum temperature of 500°C, Nozzle X prints every printable material*, from PLA all the way to Carbon Fibre-filled PEEK without wearing.
