High-Performance Solid Carbide HPC Mill for Deep Contours
This four-flute solid carbide HPC end mill in the long version is precisely designed for machining demanding cavities and deep-lying form elements. By combining a Weldon shank with a specific neck relief, clearance contours are easily navigated. The cutting tool features an unequally pitched helix, which promotes smooth operation. Thanks to the RT405 PVD-TiAlN coating, users benefit from reliable wear protection, making this end mill a solid choice for modern roughing and finishing applications.

Applications
This end mill is specifically designed for machining structural steel, tempered steel, tool steel, stainless steel, and cast iron. The extended design and integrated neck relief show their strengths especially when milling deep slots, pockets, and complex component contours. In addition to classic operations like shoulder and face milling, the tool is also suited for ramping and plunge milling due to its center-cutting capabilities.
Special features
A key feature of this tool is its vibration-reducing design. The unequal helix angle of 35°/38° counteracts harmonic oscillations and creates favorable conditions for excellent surface finishes on the workpiece. The combination of a tough solid carbide substrate and a robust TiAlN coating supports efficient machining processes with consistent results.
