Integral metal ceramic ball blade milling with two edges and two edges, high hardness and high smoothness mirror steel parts R1-R8

High-hardness hardened steel and mold steel curve finishing requires ultra-high tool performance. Ordinary carbide end mills are prone to high-temperature chip adhesion, edge passivation and obvious tool marks, failing to achieve mirror finish. Made of premium integral metal ceramic, this cutter has lower friction coefficient, higher thermal stability and better oxidation resistance than traditional carbide tools, making it the best choice for mirror finishing of hard steel.

The exclusive 75° large-angle design greatly reduces cutting load and heat generation for hard steel machining. The precisely ground 2-flute arc structure with accurate and symmetrical radius is perfect for 3D profiling, curved surface and cavity machining. The full-body mirror polishing treatment eliminates built-up edges and tool scratches fundamentally.

With excellent high-temperature resistance and oxidation resistance, the metal ceramic material maintains long-term edge sharpness and machining consistency during continuous high-speed finishing. The finished curved surface is uniform, ripple-free and mark-free, achieving standard mirror gloss directly and saving manual polishing procedures.
