Applications

This end mill is excellently suited for both roughing and finishing processes on a wide range of materials. Typical machining operations include face milling, shoulder milling, slot milling, drilling slots, ramping, and plunge milling. It is specifically designed to support efficient workflows when processing structural steel, tool steel, stainless steel, and cast iron.

Special features

Thanks to the advanced PVD-TiAlN coating (RT405), the cutting tool exhibits strong resistance against wear and thermal build-up. The unequal helix angle of 35°/38° minimizes vibrations, providing an excellent basis for smooth surface finishes. The integrated neck relief grants additional flexibility for machining deeper cavities. Available with either a cylindrical or Weldon shank, this cutter ensures a reliable grip in numerous tool holder systems.
