2 Flute Ball Nose End Mills 1mm - 10mm Milling Cutter For Copper Electrodes

Our precision-engineered 2-flute ball nose end mill is specifically designed 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).

• 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

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

• EDM Electrodes - Copper and graphite electrodes for aerospace/medical molds
• 3D Profiling - Complex contours in molds, dies, and prototypes
• High-Speed CNC - Aluminum, brass, and soft alloy machining
• Micro-Milling - Precision details (
