End Mill for Copper 2 flute flat end mill

Achieve Burr-Free Precision with SAMHO DLC-Coated 2-Flute Flat End Mills

Tackle sticky and ductile materials with ease using the SAMHO CGS4 Series. Specifically engineered for red copper, aluminum alloys, and resins, these 2-flute flat end mills feature an advanced DLC (Diamond-Like Carbon) coating. This technology provides a super-hard, low-friction surface that eliminates material smearing and built-up edge (BUE), ensuring consistent accuracy in high-speed CNC operations.

  • Anti-Adhesion: DLC coating prevents “gumming” in copper and soft plastics.

  • Mirror-Finish Flutes: Polished geometry for superior chip flow and surface quality.

  • Square Geometry: Ideal for precise slotting, shoulder milling, and flat-bottom cuts.

  • Wholesale Direct: High-performance non-ferrous tooling at competitive factory prices.

In the production of EDM electrodes and aluminum components, tool adhesion is the primary cause of poor surface finish and tool breakage. The SAMHO DLC-coated flat end mill combines a solid lubricant surface with high-rigidity carbide to deliver mirror-like finishes in non-ferrous machining.


Advanced Technical Features

  • DLC Coating for Ultra-Low Friction & Non-Stick Cutting
    The DLC coating provides exceptionally low friction and high surface hardness, essential when machining red copper and aluminum:
    • Resists Built-Up Edge (BUE): Prevents material from welding to the cutting edge
    • Reduces Cutting Heat: Allows higher speeds and feeds under dry or MQL conditions
  • Optimized 2-Flute Design for Rapid Chip Evacuation
    Ductile materials like pure copper and soft resins produce long, gummy chips. The open 2-flute geometry ensures:
    • Maximum Chip Space: Prevents clogging and chip recutting in deep slots
    • Clean Cutting Action: Burr-free edges and accurate vertical shoulders
  • Mirror-Polished Flutes for Superior Surface Finish
    Mirror-polished flute surfaces reduce friction during chip flow, ensuring:
    • Dimensional Accuracy: Minimizes tool deflection caused by radial forces
    • High Surface Quality: Delivers out-of-the-box mirror finishes on high-purity copper parts
  • Application-Specific Cutting Parameters
    SAMHO provides field-tested cutting data for copper, aluminum, and resins to optimize RPM, feed rates, and minimize setup time and tool failure risk

Target Applications & Industries

Applications:

  • EDM Electrode Machining: Precision milling of red copper and graphite-composite electrodes

Pro-Tips for Machining Ductile Materials

  • Coolant Strategy: Use MQL or high-pressure air blast to enhance chip removal and surface finish
  • High-Speed Stability: Ensure balanced tool holders (Shrink-fit or Hydraulic) to minimize runout
  • Tool Maintenance: Protect the ultra-sharp DLC edge with non-contact tool setters to prevent micro-chipping
