1mm - 12mm High Precision End Mill 4 Flute End Mill For Copper Electrodes

4 Flute Solid Carbide End Mill for Copper Electrodes High Precision EDM Graphite Copper Cutting CNC Machining

Introduction:

Our premium 4-flute solid carbide end mill is specifically engineered for precision machining of copper electrodes, graphite, and other non-ferrous materials used in EDM (Electrical Discharge Machining) applications. Designed with specialized geometry and advanced materials, this end mill delivers exceptional surface finish quality while maintaining high metal removal rates in CNC machining operations.

Features:

• 4-flute design optimized for copper and graphite machining

• Manufactured from ultra-fine grain solid carbide substrate

• Special edge preparation to prevent material adhesion

• High helix angle (45°) for efficient chip evacuation

• Precision ground cutting edges for consistent performance

• Available with optional anti-adhesion coatings

• Center cutting capability for plunge milling operations

Advantages Over Competitors

• Superior surface finish on copper electrodes (Ra < 0.4μm achievable)

• Reduced tool wear compared to standard end mills

• 30% higher feed rates enabled by optimized flute geometry

• Excellent chip clearance prevents material buildup

• Extended tool life in abrasive graphite materials

• Stable cutting performance with minimal vibration

.
