HXF multiflute end mills from Helical enable higher feed rates for finishing difficult materials. The HXF and HXF-RN end mill series feature corner radii for added strength and high-helix-angle flutes for smoother cutting and a better finish. The tools are designed for small radial depths of cut up to 6% of cutter diameter and axial depths up to 1 to 1.5 times cutter diameter. The increased number of flutes, along with the proper use of radial chip thinning techniques, will enable enhanced finishing operations and reduced cycle times. The end mills are made of submicron-grain carbide and feature geometries engineered to cut difficult material. The tools come with an AlTiN coating for oxidation resistance and extreme hardness for slotting and peripheral-milling stainless and other steels, cast irons, titanium alloys, and cobalt-, nickel-, and iron-based high-temperature alloys.
