Brief: Discover the Uncoated 3-Flute Step Forming Cutter with ultra-sharp carbide edges, designed for high-speed machining of non-ferrous materials. This custom end mill offers precision-ground tungsten carbide edges, exceptional surface finishes, and reduced cycle times with its unique 3-flute step geometry. Perfect for aerospace, electronics, automotive, and medical applications.
Related Product Features:
  • Uncoated carbide construction with micro-grain tungsten carbide for sharper cutting edges.
  • Optimized 3-flute design with balanced chip evacuation and 40° helix angle.
  • Step forming geometry with custom step heights and 90°/120° shoulder angles.
  • High-speed performance stable at 15,000-30,000 RPM, compatible with dry machining.
  • 50% longer tool life vs HSS in aluminum alloys and 30% higher feed rates achievable.
  • Burr-free edges reduce secondary finishing and OEM/ODM flexibility for custom geometries.
  • Precision-ground edges deliver exceptional surface finishes (Ra 0.2-0.8 μm).
  • Center-cutting capable for plunge milling and minimizes vibration with alternate tooth spacing.
Faqs:
  • What materials is this uncoated 3-flute step end mill suitable for?
    This end mill is optimized for non-ferrous materials like aluminum, copper, and plastics, including applications in aerospace (6061-T6, C17200 copper), electronics, automotive, and medical (Ti-6Al-4V).
  • What are the advantages of an uncoated carbide end mill?
    Uncoated carbide provides sharper cutting edges compared to coated tools, reducing material adhesion and delivering superior surface finishes. It also allows for higher feed rates and longer tool life in specific applications.
  • Can I request custom geometries for this end mill?
    Yes, OEM/ODM services are available, allowing for fully customizable geometries, including step heights (0.5-20mm), shoulder angles (90°/120°), and other specifications to meet your machining needs.
