Product Function

Designed specifically for precision machining of aluminum and non-ferrous metals, this Tungsten Carbide Micro End Mill features a Long Neck (Deep Reach) design. It is the ultimate solution for machining deep ribs, slots, and intricate pockets where standard end mills cannot reach without interference. The 3-flute geometry ensures a perfect balance between chip evacuation and surface finish, preventing chip packing in deep cavities.

Product Features

  • Specialized for Aluminum: The 3-flute design with high helix angle and polished flutes minimizes built-up edge (BUE) and ensures smooth chip removal, critical for aluminum alloys (6061, 7075, etc.).
  • Long Neck / Deep Reach: The reduced neck diameter allows for deep machining while maintaining high rigidity compared to standard long-flute tools, reducing chatter and deflection.
  • Micro Precision: Available in micro diameters (1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm) with a standard 4mm shank for high stability.
  • Premium Material: Made from Ultra-Fine Micro Grain Tungsten Carbide for exceptional wear resistance and tool life.
  • High Concentricity: High-precision grinding ensures tight tolerances, essential for micro-machining applications.

  • Coolant: Flood coolant or Oil mist is highly recommended to prevent aluminum adhesion.
  • Strategy: For deep ribs, use smaller step-downs (Ap) to reduce tool deflection.

FAQ

Q1: Is this tool suitable for steel machining? A1: No, this 3-flute geometry is optimized for Aluminum and non-ferrous metals. For steel, we recommend our 4-flute coated series.
Q2: What is the advantage of a "Long Neck" over a "Long Flute"? A2: A long neck tool has a relieved shank behind the cutting edge. This is much more rigid than a long flute tool, reducing vibration and breakage when reaching into deep cavities.
Q3: Do you offer coating for these tools? A3: Standard stock is uncoated (bright finish) which is often best for aluminum to keep the edge sharp. However, we can provide DLC (Diamond-Like Carbon) coating upon request for extended tool life.
Q4: What is the lead time? A4: For items in stock (like the specifications listed above), we ship within 24-48 hours.
Q5: Can I customize the effective length? A5: Yes, as a manufacturer, we can customize the neck length or cutter diameter to your specific requirements. Please contact sales for a quote.
