20mm 12 Flutes End Mills For Finishing Operations In Hardened Metals

This 20mm diameter, 12-flute carbide end mill is a precision cutting tool optimized for finishing operations in hardened metals (e.g., tool steels, D2, H13, stainless steel, and heat-treated alloys up to ~60 HRC). Its high flute count ensures a superior surface finish while maintaining efficiency in high-speed machining (HSM) applications.

• Material: Solid carbide (ultra-fine grain) for extreme hardness & wear resistance.
• 12 Flutes: Maximizes edge contact for smoother finishes in finishing passes.
• Optimized Geometry:
  • High helix angle (~35°-45°) for better shearing & reduced cutting forces
  • Variable pitch (if available) to minimize harmonics & vibration
• Advanced Coatings:
  • TiAlN/AlTiN - Best for high-heat resistance in hardened steels
  • Diamond-like coatings (DLC) - For non-ferrous or abrasive composites
• Short-to-medium length (reduces deflection for precision in hard metals)

• Finishing molds & dies (e.g., injection molds, stamping dies)
• Aerospace components (hardened alloys, turbine parts)
• Medical implants & precision tooling (where surface finish is critical)
• High-speed CNC machining (finishing passes at high RPMs)
