What the Micro Swiss M2 hardened nozzle does

The Micro Swiss M2 Hardened High Speed Steel Nozzle is a RepRap-style M6 nozzle for 1.75mm filament that combines high-temperature capability, abrasion resistance, and non-stick performance. It is built for users who need a more wear-resistant nozzle than standard brass options while keeping a 0.4mm printing setup.

Key features of the hardened steel 0.4mm nozzle

• M2 high speed steel construction for high-temperature use and improved durability.
• Hardened and tempered to 68 HRC for a wear-resistant nozzle body.
• Electroless nickel plating to add surface protection and non-stick properties.
• 70-73 HRC plating hardness for a hard plated surface layer.
• WS2 coating to further reduce sticking during material flow.
• 0.035 coefficient of friction for low-friction material passage.
• 0.4mm orifice for standard-detail FDM printing with 1.75mm filament.
• Made in USA by Micro Swiss.
• Limited lifetime warranty against wear.

Where an M6 hardened nozzle is useful

This RepRap nozzle is well suited to printing jobs where nozzle wear, elevated temperatures, or material sticking are concerns. The hardened M2 steel body, electroless nickel plating, and WS2 coating make the Micro Swiss nozzle a practical choice for users looking for a longer-lasting 0.4mm M6 nozzle for regular 1.75mm filament printing.
