This is a new Kennametal HARVI solid carbide end mill, part number HA3R6RA0625R125HAR030, in KCSM15A grade — a PVD TiN-family (gold-colored) AlTiN-based coating optimized for high-performance milling of steels, stainless steels, and high-temperature alloys. The tool features a 5/8 in (0.625 in) cutting diameter, 6 flutes, a 0.030 in corner radius, 1 in length of cut, 5/8 in shank diameter, and 3-1/2 in overall length, as decoded from the part number and confirmed on the label. The HARVI series geometry employs variable helix and variable pitch flute spacing to suppress chatter and enable aggressive material removal rates in demanding aerospace, die/mold, and general steel milling applications. Compatible with standard 5/8 in straight-shank toolholders including ER, Weldon, and hydraulic chucks. Made in USA.
