The MH(350) 2 Flute Ball Nose End Mill combines ultra-fine grain carbide with AlCrN PVD coating for high-speed and dry machining. It is designed for hardened steel up to 52 HRC, stainless steel, copper, titanium alloys, and other difficult materials.
The MH(350) 2 Flute Ball Nose End Mill is a solid carbide tool designed for 3D contouring, curved-surface machining, profiling, and finishing.
It features a 0.3–0.4 μm ultra-fine grain carbide substrate with a high-performance AlCrN PVD coating for wear resistance and stable cutting performance.
The AlCrN coating provides excellent oxidation resistance and hot hardness, with high-temperature performance of approximately 1000°C.
Its strong resistance to material adhesion also helps reduce built-up edge (BUE) when machining stainless steel.
Key Features & Benefits
0.3–0.4 μm Ultra-Fine Grain Carbide
The ultra-fine grain carbide substrate provides a stable and wear-resistant cutting edge.
It is well suited to high-speed machining and applications where edge stability is important.
AlCrN PVD Coating
The AlCrN PVD coating offers excellent oxidation resistance and hot hardness.
Its high-temperature performance helps maintain cutting stability under demanding machining conditions.
2-Flute Ball Nose Geometry
The 2-flute ball nose design is suitable for 3D contouring, curved surfaces, profiling, and finishing.
It provides a practical balance between cutting stability and chip evacuation for demanding milling applications.
Strong Resistance to Material Adhesion
Stainless steel can cause material buildup and built-up edge during machining.
The MH(350) is designed to reduce adhesion and help maintain a cleaner, more stable cutting edge.
High-Speed and Dry Machining
The MH(350) is designed for high-speed cutting and dry machining, where heat generation can affect tool life and cutting stability.
It can also be used with coolant when required by the machining process.
