  • INDUSTRY-GRADE CARBIDE PERFORMANCE: Micrograin tungsten carbide construction delivers 3X longer tool life than standard end mills, withstanding temperatures up to 1000°C for precision machining of hardened steels, alloys, and composites.
  • NANO BLUE COATING TECHNOLOGY: Advanced heat-resistant coating outperforms TiAlN/TiCN in thermal stability, reducing friction by 40% while maintaining cutting edge sharpness for mirror-finish results on copper, magnesium, and high-silicon aluminum.
  • PRO-GRADE TOLERANCE CONTROL: ±0.02mm (±20μm) runout tolerance ensures CNC-level accuracy for deep cavity milling applications in mold making and aerospace components.
  • MULTI-MATERIAL VERSATILITY: 4-flute design optimized for steel, cast iron, and non-ferrous metals - includes pre-hardened steel machining capability with built-in chip breakers for clean swarf removal.
