Designed for efficient stock removal on tough materials, this end mill delivers stable performance through a balanced combination of geometry and metallurgy. The 4-flute configuration provides a good balance between feed rate and surface finish, while the NRA asymmetrical coarse pitch supports effective chip control and reduced cutting forces. The powder-metallurgical HSS-E construction enhances wear resistance and hot hardness, helping extend tool life in demanding milling scenarios. A robust 16 mm Weldon shank ensures reliable clamping in standard holders, making it a dependable choice for precision roughing in steel, stainless steels, cast irons, and some high-temperature alloys.
