2 Flute Ball Nose End Mill For Copper Electrodes CrN Coated Carbide High Speed CNC Anti-Galling Design Precision EDM Mold Making 1mm-10mm

Introduction:

Our 2-flute ball nose end mill is precision-engineered for high-performance machining of copper electrodes, graphite, and non-ferrous alloys. Featuring a CrN (Chromium Nitride) coating and optimized ball nose geometry, it delivers superior wear resistance, reduced material adhesion, and exceptional surface finishes—ideal for EDM electrode manufacturing, mold making, and precision CNC applications.

Crafted from ultra-fine grain solid carbide, this tool outperforms standard end mills in tool life, cutting speed, and chip evacuation, especially in sticky materials like pure copper (C11000) and beryllium copper (C17200).

Features:

• ✔ 2-Flute Ball Nose Design – Optimized for smooth 3D contouring and fine-detail work.
  ✔ CrN Coating – Enhances hardness (2,200 HV) and prevents copper adhesion.
  ✔ High Helix Angle (35°) – Improves chip flow and reduces heat buildup.
  ✔ Precision Ground Edges – Ensures consistent radii (±0.005mm) for accuracy.
  ✔ Center Cutting – Allows plunge milling and slotting.
  ✔ Diameter Range – 1mm to 10mm (standard), with custom sizes available.

Advantages Over Competitors

✅ 50% Longer Tool Life – CrN coating resists wear and reduces galling.
✅ Mirror-Like Finishes (Ra < 0.2μm) – Minimizes post-EDM polishing.
✅ Higher Feed Rates – Efficient chip clearance enables faster machining.
✅ Stable Cutting – Reduced vibration in deep cavities and thin-wall geometries
