R6 Radius 4 Flute DLC Coated Carbide Ball End Mill Specialized Aluminum CNC Milling Cutter

Introduction:

The R6 Radius 4-Flute DLC Coated Carbide Ball End Mill is engineered for high-performance aluminum machining, delivering exceptional finish quality and extended tool life in demanding CNC applications. Featuring a precision R6 ball nose radius (12mm diameter) and Diamond-Like Carbon (DLC) coating, this end mill prevents material adhesion while maintaining ultra-sharp cutting edges for superior 3D contouring results. The 4-flute high-helix design optimizes chip evacuation, making it ideal for aerospace components, automotive parts, and precision mold making.

Features:

✔ R6 Ball Nose Radius – Perfect for complex 3D surfaces and smooth radius machining

✔ DLC Coating Technology – Ultra-low friction surface prevents aluminum buildup (BUE)

✔ 4-Flute High Helix (45°) – Efficient chip evacuation at high RPM (up to 40,000)

✔ Solid Micro-Grain Carbide – Japanese-grade substrate for maximum rigidity & wear resistance

✔ Optimized for Aluminum – Special edge prep reduces cutting forces & improves finish

✔ Precision Ground Cutting Edges – ±0.01mm tolerance for consistent performance

Advantages Over Competitors

✅ 5-8X Longer Tool Life vs uncoated carbide in aluminum

✅ Mirror-Like Surface Finish (Ra 0.2-0.4μm achievable)

✅ Reduced Cutting Forces – Allows higher feed rates without vibration

✅ Non-Stick Performance – DLC coating repels material adhesion
