Applications

This ball nose cutter is specifically designed for medium machining and finishing of three-dimensional contours. The tool supports efficient workflows during profile milling, shoulder milling, and copy milling of steel, stainless steel, and cast iron. The geometry also allows for direct plunging (ramping), providing significant flexibility for machining cavities and complex shapes.
Special features
The high-performance PVD-TiAlN coating of the RT405 grade protects the solid carbide substrate from premature wear and improves thermal stability during the cutting process. This creates excellent conditions for achieving high surface qualities. Additionally, the 4-flute, centre-cutting design ensures smooth operation and high dimensional accuracy on complex workpiece geometries.
