A cast then fully machined, fully Tungsten Carbide Nozzle.

• .4mm, .5mm orifice, spacers also available to use them with Volcano heatblocks. 
• V6 compatible. Will work in a Mk8 Creality machine I guess, but will be a bit long, so careful with your Z height.
• 7mm hex to be *incompatible* with the mosquito magnum+ heat shield.

0.5mm is preferred by some for hardened nozzles as some filaments may have say, carbon fibres longer than 0.4mm that will clog a 0.4mm. Obviously being TC, you can torch them clean.

V1 is not "high flow", and testing has shown it to be similar to a "normal" nozzle. It is still fully TC and will last, but is not "high flow".
