What this hardened RepRap nozzle is for

The Micro Swiss M2 Hardened High Speed Steel Nozzle is an M6-thread nozzle for 1.75mm filament that delivers high-temperature performance, abrasion resistance, and low-friction material flow through a 0.6mm orifice.

This nozzle is machined from M2 high speed steel, then hardened and tempered to 68 HRC. It is further finished with electroless nickel plating and a WS2 coating to improve surface performance and non-stick behaviour.

Key features of the Micro Swiss M2 nozzle

• M2 hardened high speed steel construction: machined from M2 high speed steel and hardened to 68 HRC.
• Built for high temperatures: designed for high-temperature printing applications.
• Abrasion-resistant nozzle body: intended for demanding printing conditions where wear resistance matters.
• Electroless nickel plating: adds a plated surface layer with a hardness of 70-73 HRC.
• WS2 coating: provides superior non-stick properties.
• Low friction surface: coefficient of friction is 0.035.
• 0.6mm nozzle size: suitable for users who want a larger nozzle diameter than standard fine-detail sizes.
• Made in USA by Micro Swiss: country of manufacture is specified by the manufacturer.
• Limited lifetime warranty against wear: included manufacturer wear coverage.

Where a 0.6mm hardened M6 nozzle fits best

This 0.6mm RepRap nozzle is suited to users who need a durable M6 replacement nozzle for 1.75mm filament setups. The hardened M2 steel body, nickel plating, and WS2 coating make it a practical choice where heat resistance, abrasion resistance, and reduced sticking are important.

The larger 0.6mm orifice can also be useful for prints that benefit from broader extrusion paths. For users searching for a hardened M6 nozzle for 1.75mm filament with non-stick coating, this Micro Swiss nozzle combines the specified material hardness, plated surface hardness, and low-friction coating in one part.
