This end mill is crafted for deep profiling where accuracy and surface finish matter. The long-series geometry provides extended reach for cutting deeper features without compromising rigidity, while the four flutes balance efficient material removal with smooth chip evacuation. The 30° helix and 12° rake angle optimize cutting action in the specified workpiece materials, helping to reduce rubbing and improve surface quality. The powder-metallurgical HSS-E base offers enhanced wear resistance and toughness compared to conventional high-speed steels, delivering longer tool life in repetitive milling cycles. The DIN 844 L standard ensures compatibility with common tool holders, simplifying setup and interchangeability in professional shop environments.
