The AlTiN-coated 3-flute carbide end mill is designed for optimal performance in high-temperature, high-feed environments.
Key features include:
• Material: Ultra-fine grain carbide substrate (92 HRA hardness) for exceptional wear resistance and edge stability.
• Coating: Multi-layer AlTiN PVD coating
(3-5um thickness) with oxidation resistance up to 900°C, outperforming traditional TiN and TiAIN coatings.
• Geometry: 45° helix angle and variable pitch design to minimize vibration and enhance chip evacuation during deep-pocket and contour milling.
• Applications: Ideal for hardened steels
(HRC50+), stainless steel (304/316), titanium alloys (Ti-6Al-4V), and Inconel
718.
Performance Advantages
✅ 3x Longer Tool Life
- The AlTiN coating’s superior thermal stability reduces flank wear by 40% in high-speed dry machining, extending tool lifespan to 3–4x versus uncoated counterparts. Rigorous testing on SKD11 mold steel (HRC52) demonstrated consistent performance at 220 m/min cutting speeds.
✅ High-Speed Machining Efficiency
- Optimized for dry cutting and MQL (Minimum Quantity Lubrication), the tool achieves feed rates up to 0.15mm/tooth while maintaining surface finishes as fine as Ra0.8μm in semi-finishing operations.
✅ Versatile Material Compatibility
- Engineered for challenging materials:
- Aerospace: Titanium alloys and Inconel components with reduced thermal deformation.
- Automotive: High-efficiency roughing of engine blocks and transmission housings.
- Mold Making: Precision finishing of hardened steel dies (e.g., S136, H13) with minimal tool deflection.
✅ Economic and Environmental Benefits
- Regrindable up to 5 times, reducing long-term tooling costs by 35% in high-volume production.
- RoHS-compliant coatings and compatibility with eco-friendly MQL systems align with sustainable manufacturing goals.
