Key Features & Benefits
1. Ultra-Hard Carbide Substrate
Manufactured from micro-grain tungsten carbide for enhanced rigidity and fracture resistance.
Optimized for machining materials up to HRC56 hardness, including tool steels (D2, H13), stainless steels (304, 316), and high-temperature alloys.
2. Advanced Coating Technology
TiAlN (Titanium Aluminum Nitride) Coating - Provides excellent heat resistance (up to 900°C), reducing tool wear in high-temperature cutting.
AlTiN (Aluminum Titanium Nitride) Coating - Offers higher oxidation resistance and lubricity, ideal for dry machining and high-speed applications.
Nanocoatings - Some variants feature multilayer nano-coatings for extended tool life in extreme conditions.
3. Optimized Geometry for High Performance
Variable Helix & Uneven Flute Spacing - Reduces vibration and harmonics, ensuring smoother cuts and extended tool life.
High Shear Rake Angles - Enhances chip evacuation, preventing built-up edge (BUE) and reducing cutting forces.
Corner Strengthening - Reinforced corner designs (e.g., bull-nose or corner radius) minimize chipping in hardened materials.
4. Versatile Cutting Capabilities
Slotting, Plunging, and Contouring - Designed for full-depth slotting and high-efficiency ramping.
Wet & Dry Machining - Suitable for both coolant-assisted and dry cutting environments.
High-Speed Machining (HSM) Compatible - Engineered for high RPM operations with minimal deflection.
5. Extended Tool Life & Cost Efficiency
Reduced tool changes due to superior wear resistance.
Consistent performance in long-run production, lowering per-part machining costs.
