Creality K1 Series / CR-M4 Nozzle Kit – Copper Alloy & Hardened Steel

Creality nozzle kit for K1 series and CR-M4 3D printers. Includes both copper alloy nozzles for standard filaments and hardened steel nozzles for abrasive materials. Multiple sizes for versatile printing options.

Kit Contents: Copper alloy nozzles (0.4mm x2, 0.6mm x1, 0.8mm x1) + hardened steel nozzles (0.4mm x2, 0.6mm x1, 0.8mm x1)

Note: Same length as volcano nozzle but with slightly longer head. May not be compatible with BLTouch or similar auto-leveling sensors.

Maintenance Tip: For best results, use the copper nozzles for standard filaments and switch to hardened steel when printing abrasive materials (CF/GF filled) to reduce wear.
