Key Features & Benefits
- Advanced Diamond Coating: Offers exceptional hardness (up to 10,000 HV) and low friction, ensuring superior wear resistance and extended operational life.
- Optimized 4-Flute Geometry: Designed for efficient chip evacuation and stability during deep groove milling, resulting in excellent surface finishes and dimensional accuracy.
- High Thermal Conductivity: The diamond layer effectively dissipates heat from the cutting zone, preventing tool degradation and maintaining workpiece integrity.
- Versatile Round Nose Design: Ideal for contouring, profiling, and 3D milling applications, providing smooth transitions and high-quality surface finishes.
- Premium Carbide Substrate: Manufactured from high-quality micro-grain carbide rods from Japan and Germany, ensuring maximum rigidity and tool strength.
Primary Applications
- Graphite Machining: Perfect for creating graphite electrodes for EDM processes, molds, and other high-temperature applications.
- Fiberglass & Composites: Reliably cuts through abrasive materials like fiberglass (GFRP), carbon fiber (CFRP), and other composites without causing delamination or excessive tool wear.
- Non-Ferrous Materials: Can also be effectively used on other abrasive non-ferrous materials where long tool life is critical.
