Phaetus PMK8 Hardened Steel Nozzle 1.75mm

In 3D printing filaments, composite consumables containing abrasive additives such as carbon fiber, steel, wood, boron carbide, tungsten and phosphorescent pigments are often very hard. The use of ordinary nozzle printing, will soon wear holes and inner diameter, destroying the original performance of the nozzle.
Mohs type hardness of the hardened steel nozzle is 7.8.

Hardness over HRC60 makes an minimum wear at the hole size after a long time printing with abrasive materials. Temperature resistance up to 450°C allows printing with special engineering plastics such as PEEK.
Special processing technology and post-treatment make the nozzle without burr at the edge of tip and without debris in the hole.
Inner hole roughness lower than Ra0.4; Higher smoothness and less adhesion.
Min. orifice diameter 0.1mm/±0.01mm to ensure high accuracy printing.

Features:

• Material: hardened steel
• Hardness: 60HRC
• Diameter tolerance of the nozzle bore: +/- 0.01mm
• Roundness tolerance: =0.02mm
• Filament diameter: 1.75mm
• Maximum printing temperature: 450 ° C

Compatible with MK8 style HotEnds
