Features: 100% brand new and high quality With removable pointed Stainless Steel tips.Its easy to change nozzle tips in time when the filment block it. The 3D printer extruder nozzles has impressive toughness and hardness, suitable for common 1.75 mm. 3D printer filaments. The inner wall of the nozzle is smooth and has no burrs, its viscosity coefficient is small, and extruder nozzle diameter error is less than 0.02 mm, providing you an accurate and smooth extrusion A torque wrench is required during the installation of the nozzle. Facilitate your timely replacement, achieving quality printing A big problem with small, hot and slow prints is the heatradiation of the hotend and nozzle itself. To get as little as possible heat into the print, the nozzle needs to be as long and pointy as possible. The longer the nozzle, the bigger the distance between heaterblock and the print. And the more pointy it is, the less heat radiation can affect the print.
