Precision Super-hard Ceramic Ball-nose Milling Cutter with Cylindrical Shank for Aerospace and Auto Mold Machining

Bullet Points

1. Ultra-hard Wear-resistant Substrate：Nano-grade silicon nitride/alumina ceramic with HRA80-85 hardness, 5x higher wear resistance than carbide tools, 300%+ longer service life, greatly cutting tool change costs

2. Anti-chipping Ball-nose Design：Arc edge + gradient structure (hard outside & tough inside) disperses cutting force evenly, 40% lower chipping risk, ideal for 3D precision milling of complex aerospace mold surfaces

3. High-temperature Dry Cutting：Withstands 1200℃ high temperature, enables coolant-free machining, 2-3x faster cutting speed (up to 150-300m/min), eco-friendly & cost-saving

4. Micron-level Machining Accuracy：Cylindrical shank with ≤0.002mm concentricity, machining surface roughness as low as Ra0.1μm, meeting strict tolerance requirements of aerospace & auto mold industries

5. Ideal for Hard-to-machine Materials：Easily cuts nickel-based superalloys (e.g. Inconel 718), titanium alloys & composites, 80% less tool change frequency, significantly boosting productivity
