Helical Solution has launched the seven-flute HSF-7 end mill designed for finishing steel and exotic materials with increased feed rates, suitable for all finishing applications but especially useful for the demanding aerospace industry. The center-cutting HSF-7 is crafted of certified premium sub-micron grain carbide and feature geometries specifically engineered to cut difficult-to-machine materials. The tools are available with an AlTiN (titanium aluminum nitride) coating for oxidation resistance and extreme hardness for peripheral milling in steels, stainless steel, cast irons, titanium alloys as well as cobalt-, nickel- and iron-based high-temperature alloys.
