What the Micro Swiss M2 nozzle is for

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 improved non-stick performance. The 0.8mm orifice supports higher-flow printing while using a hardened steel construction built for demanding materials and longer service life.

Key features of the hardened steel nozzle

• M2 high speed steel construction: The nozzle is machined from M2 high speed steel for durability in higher-wear printing environments.
• Hardened and tempered body: The nozzle is hardened and tempered to 68 HRC.
• Electroless Nickel plating: The plated surface adds protection, with a stated plating hardness of 70-73 HRC.
• WS2 coating: The WS2 coating is used to improve surface performance and support superior non-stick properties.
• Low friction surface: The stated coefficient of friction is 0.035.
• 0.8mm nozzle diameter: The larger orifice size is suited to applications where increased extrusion volume is needed.
• Made in USA: Manufactured by Micro Swiss in the USA.
• Wear coverage: Includes a limited lifetime warranty against wear.

Where a 0.8mm hardened nozzle makes sense

This 0.8mm Micro Swiss nozzle is suited to users who need a larger nozzle opening with a durable, wear-resistant material path. It fits applications where abrasion resistance, high-temperature operation, and reduced sticking at the nozzle surface are important to the print process.

The M6-thread RepRap format also makes the nozzle relevant for compatible 1.75mm hotend setups that require a hardened alternative to standard brass nozzles.
