Helical Solutions’ new HEVR-5 and HEVR-RN-5 five-flute, variablepitch endmills are designed for roughing and finishing of steel and exotic materials with increased feed rates and reduced chatter, the company said. HEVR-5 and the longer-reach, reduced- neck HEVR-RN-5 tools are crafted of certified premium sub-micron grain carbide and feature geometries specifically engineered to cut ferrous material. The tools are available with an AlTiN (titanium aluminum nitride) coating for oxidation resistance and extreme hardness for slotting, peripheral milling, ramping and helical interpolation of Stainless and other steels, cast irons, titaniumalloys aswell as cobalt- nickel- and iron-based hightemperature alloys. The HEVR-5 tool series features corner radii for added strength and has a variable-pitch design for increased depth of cut, up to 1 times the diameter of the tool. The HEVR-RN-5 series is designed for applications requiring extended reach into pockets ormachining around obstructions. The stub flute length and a reduced neck contribute to rigidity. Speeds and feeds for the tools range from 80 to 250 SFM and 9 to 27 IPM for stainless, 60 to 125 SFM and 2 to 10 IPM for high-temperature alloys, 500 to 600 SFM and 23 to 76 IPM for steels, 400 to 600 SFMand 24 to 73 IPM for cast irons and 160 to 190 SFMand 7 to 15 IPM for titanium. These tools are available in 1/4 inch, 5/16 inch, 3/8 inch, 1/2 inch, 5/8 inch, 3/4 inch, 1 inch and 1-1/4inch diameters.
